MEF advances its LSO architecture with 2 new specifications

MEF published two new specifications advancing the orchestration of MEF 3.0 connectivity services over multiple network layers, including the optical domain. Both standards were developed within MEF’s LSO (Lifecycle Service Orchestration) Reference Architecture.

Network Resource Management (NRM) – Information Model (MEF 59) -- defines the information model to facilitate the orchestration of Carrier Ethernet connectivity services through WAN SDN controllers, OTN subnetwork managers, and legacy network management systems. The MEF NRM model is specified in Papyrus UML and is based on current and developing best network management solutions by ITU-T, ONF, and TM Forum to allow for wider interoperability across multi-vendor and multi-technology platforms. This approach also facilitates upcoming work on OAM and OTN.

Along with the LSO RA, the MEF NRM serves as a basis for the new MEF 60 specification and thus supports the LSO Presto interface.

“MEF is playing a leading role to deliver the seamless management of services and resources in a multi-carrier, multi-vendor, multi-technology environment,” said Andrea Mazzini, editor of MEF 59 and Senior Systems Engineer, Nokia. “Interoperable network management models are a fundamental part of the picture and play a key role in the standardization of agile, assured, and orchestrated end-to-end connectivity.”

CenturyLink, Ciena, Cisco, Coriant, Ericsson, Huawei, Infinera, NEC, and RAD joined Nokia in contributing to MEF 59.

Network Resource Provisioning – Interface Profile Specification (MEF 60) -- provides an abstracted, intent-based solution for activation of – as well as topology retrieval of – network resources in support of MEF-defined services. The specification is complemented by an enhanced LSO Presto SDK (software development kit) that has been made available to the MEF Developer Community on the MEF GitHub.

"The CenturyLink-led MEF 60 provides an essential solution in the overall development of the MEF LSO portfolio of APIs,” said Jack Pugaczewski, editor of MEF 60 and Distinguished Architect, CenturyLink. “This development effort is a great example of a traditional standards development and open source hybrid, which resulted in a quality, expedited specification alongside the release of a corresponding API and SDK."

“MEF 60 is an excellent illustration of standards collaboration between industry organizations,” said Pascal Menezes, CTO, MEF. “Specifically, MEF 60 leverages ONF’s TAPI model for network resource activation and topology. The LSO Presto NRP API already is integrated into an OpenDaylight SDN controller plug-in, created by the MEF Developer Community working alongside the ODL UNI Manager project. And LSO Presto NRP service provisioning scenarios will be tested as part of the OIF 2018 SDN Transport API Interop Demo.”

CenturyLink, Amartus, Ciena, Cisco, Coriant, Ericsson, Huawei, Infinera, Iometrix, NEC, Nokia, and RAD contributed to MEF 60.

“MEF members have been working diligently to develop and demonstrate model-driven ‘North-South’ intra-provider LSO APIs and ‘East-West’ inter-provider LSO APIs that are required to orchestrate MEF 3.0 services,” said Nan Chen, President, MEF. “The new specifications enable us to define the critical LSO Presto NRP (Network Resource Provisioning) API for orchestrating services over a mix of underlying network technologies. We thank the LSO project teams for their diligent work and look forward to also sharing more good news related to inter-provider orchestration in the coming months.”

This week at OFC in San Diego, the Optical Internetworking Forum (OIF) is conducting a series of multi-vendor interoperability demonstrations showFlexE), 112 Gbps per lane live electrical signaling and end-to-end optical links using CEI-56G-VSR electrical interfaces.
casing three significant technologies; Flex Ethernet (

There are 14 participating companies including Amphenol, Credo Semiconductor, Fiberhome Telecommunications Technologies Co., Ltd., Finisar, Huawei Technologies Co., Inphi, Keysight Technologies, Molex, TE Connectivity, Tektronix, VIAVI Solutions, Xilinx, Yamaichi Electronics, and ZTE Corporation.

Flex Ethernet Demo -- the FlexE technology from the OIF extends standard Ethernet with bonding, subrating, and channelization features and is defined in the FlexE v1.0 Implementation Agreement. The demo features interoperability among member companies using combinations of these three features over multiple types of 100 GbE.

56 Gbps Demo -- this demo features multiple silicon suppliers operating over a 56 Gbps PAM4 VSR (chip to module) link reflecting the recently published CEI 4.0 document that includes this 56 Gbps PAM4 channel definition. The 56 Gbps demo will electrically drive interoperating optical modules, interconnected with fiber, showing a full multi-vendor electrical-optical-electrical link from host-to-host. The broad range of technologies and suppliers participating in the demo indicates the maturing industry ecosystem around 56 Gbps signaling.

112 Gbps Demo -- the OIF recently began new projects to define 112 Gbps per lane interoperable serial electrical channel definitions. As part of that effort, the OIF will be presenting two 112 Gbps serial electrical demos at OFC 2018. The first demo will include a silicon chip driving a VSR (chip to module) channel and the second will have a silicon chip driving a direct attach copper cable assembly. 112 Gbps electrical signaling is regarded as a necessary technology to enable future signaling bandwidth requirements.

“The OIF continues to test and validate the implementation agreements the forum is working on or has recently completed,” said Steve Sekel of Keysight Technologies, Inc. and the OIF’s Physical and Link Layer Interoperability Working Group Chair. “The OIF recently published both CEI revision 4.0 which includes CEI-56 Gbps requirements and the FlexE revision 1.0 specification. The forum also started work on four CEI-112 Gbps projects so this demo provides important insight into the potential technical solutions.”

OIF advances Common Electrical I/O for 56 Gbps

The OIF has published “Common Electrical (I/O) CEI 4.0” with a focus on Serdes standards for 56 Gbps.

The result is a number of carefully optimized channel definitions, paving the way for a range of interoperable solutions at 56 Gbps data rates. Key to this effort was aiming for the lowest possible power dissipation for each application while balancing link budget and latency. At this time the OIF is releasing CEI 4.0 with the following new clauses:


  • CEI-56G-USR-NRZ: Ultra Short Reach, die-to-die inside muti-chip-modules, NRZ modulation
  • CEI-56G-XSR-NRZ: Extra Short Reach, chip-to-driver, NRZ modulation
  • CEI-56G-VSR-PAM4: Very Short Reach, chip-to-module, PAM-4 modulation
  • CEI-56G-MR-PAM4: Medium Reach, chip-to-chip, one connector, PAM-4 modulation
  • CEI-56G-LR-PAM4: Long Reach, chip-to-chip, two connectors over backplane, PAM-4 modulation
  • CEI-56G-LR-ENRZ: Long Reach, chip-to-chip, two connectors over backplane, ENRZ modulation

“The industry continues to face challenges for diverging requirements regarding link latency and concerns with power consumption at the higher data rates,” said Klaus-Holger Otto of Nokia and the OIF Technical Committee Chair.  “Documenting channel definitions in more granular reaches and multiple  modulation schemes allows for the optimization of silicon chip designs, channel architectures and network operator use cases. These parameters for 56 Gbps will be used as building blocks for protocol specifications written by other organizations across the industry so the forum wanted to provide definitions that met their unique needs.”

Acacia ships pluggable coherent CFP2-DCO module for 100/200G

Acacia Communications has begun commercial shipment of a new pluggable coherent CFP2-DCO module supporting 100 Gbps and 200 Gbps transmission in a range of network applications such as including data center interconnect, metro access, metro core, long-haul, as well as emerging applications including remote PHY and client optical interfaces up to 80 km. 

The CFP2-DCO supports four times the faceplate density of the CFP-DCO.  Acacia’s CFP2-DCO incorporates its Meru DSP ASIC, based on 16nm CMOS technology, and its silicon photonic integrated circuit. Internal layer 1 encryption can be enabled for enhanced security applications. The technology was first sampled in 2016.

Acacia said these CFP2-DCO modules help to simplify network management and reduce operations costs for providers. The believes that these compact pluggable modules will allow its customers to offer some of the lowest power solutions available in the optical transport industry. 

Key advantages of the CFP2-DCO form factor compared to alternative coherent architecture:

  • Pay-as-you-grow deployment model – Defers the deployment cost, including that of the digital signal processor (DSP), of additional ports until additional bandwidth is needed.
  • Digital host interface – Streamlines integration into existing network equipment and supports field plugability without the need for complex calibration.   The use of pluggable optics means that a failure in a single module will affect only the module's port, not the entire line card.
  • Flexible modulation – 100 Gbps transmission using QPSK modulation for metro-core and long-haul applications and 200 Gbps for metro-access applications using either 16QAM for backward compatibility or 8QAM for greater reach and fewer regeneration stages.

“Our team has done a great job to develop this low power solution, while maintaining high performance. With the Optical Internetworking Forum (OIF) developing a CFP2-DCO Implementation Agreement, the form factor is positioned for wide adoption in the optical networking industry and with support for up to 400 Gbps, the CFP2-DCO form factor can offer network operators a long-term return on investment,” said Benny Mikkelsen, Founder and Chief Technology Officer of Acacia Communications.

OIF starts work on long reach and medium reach CEI-112G

The Optical Internetworking Forum (OIF) has begun work on long reach (LR) and medium reach (MR) CEI-112G. The goal is to define an interface to enable high-loss 112G backplane channels. This project will also facilitate direct attach copper (DAC) cable channel links at 112G. The CEI-112G-MR project will develop specifications for a chip-to-chip (c2c) interface which can also be used to support applications of 112Gx2 (224G), and 112Gx4 (448G) with reduced power, complexity, and enhanced density.

The CEI-112G-LR project builds upon two existing 100G serial electrical link projects.

“These projects build upon the relevant and foundational 56G and 112G CEI roadmap the OIF has established,” said Nathan Tracy of TE Connectivity and OIF vice president of marketing.  “The industry continues to look to the OIF to deliver interoperable implementation agreements that will drive adoption of both 100 Gb/s serial applications and the interfaces needed to address higher bandwidth.”

OIF Updates Micro Intradyne Coherent Receiver IA for 400G

Optical Internetworking Forum (OIF) announced updates to its Micro Intradyne Coherent Receiver implementation agreement. The IA introduces three classes of receivers, distinguished by their RF frequency response, to support Flex Coherent DWDM transmission to 400G and beyond.

The OIF said it continues its efforts to look beyond 100G by selecting a 400G implementation technology option. The newly published Flex Coherent DWDM Transmission framework document specifies a single technical approach for diverse network applications, including long-haul (LH), metro and data center inter-connection (DCI). One of the objectives of this work is to provide direction on the technical developments required by system and component providers.

“Our system vendor members continue to flow down future system requirements so that component suppliers can be ready with products to support their designs,” said Karl Gass of Qorvo and the OIF’s Physical and Link Layer Working Group – Optical Vice Chair.

The OIF is currently planning its next global transport SDN Interop demo and seeking input from the service provider community, including those that have not participated in past interop demonstrations.

In addition, the following officers were re-elected to one-year terms:
Klaus-Holger Otto of Nokia - Technical Committee, Chair; Ed Frlan of Semtech - Technical Committee, Vice Chair; Lyndon Ong of Ciena - MA&E Committee Co-Chair, Networking; Brian Holden of Kandou Bus - MA&E Committee Co-Chair, Physical & Link Layer.

OIF approves virtual transport network service IA

The Optical Internetworking Forum (OIF), which met recently in Ljubljana, Slovenia for a quarterly technical committee conference, announced that it has approved an implementation agreement (IA) for an optical virtual transport network service (VTNS) and also made progress on the 400G-ZR project.

VTNS IA

A virtual transport network service (VTNS) constitutes the creation and delivery of a virtual network (VN) by a provider to a user based on the virtualisation of transport network resources. VNs can be dynamically created, deleted or modified, while users are able to perform connection management, monitoring and protection within the VN.

In specifying the new VTNS IA, OIF aims to identify the requirements and characteristics of different virtual network service types, such as dynamic and static behaviours. The new IA is also intended to define the attributes and parameters required for these service types and the requirements for support of service recovery and OAM.

The OIF noted that different types of VTNS could be associated with operators offering, for example, bandwidth-on-demand (BoD) services, network-as-a-service (NaaS) or network slicing for 5G networking.

400G-ZR update

The OIF's 400G-ZR interoperability project, launched in November 2016, was formed to address both 400 Gbit/s ZR and short-reach DWDM multi-vendor interoperability requirements, such as might be required for cloud-scale data centre interconnect (DCI) applications. It noted that the project has now received 10 technical contributions relating to areas including power consumption of DSP, FEC proposals, and experimental demonstrations.

In addition, it was announced that at the recent quarterly meeting the OIF elected Tad Hofmeister of Google to its board of directors, filling a vacant seat on the board.

NEC/Netcracker partners with Infinera and Juniper on Transport SDN

NEC and its subsidiary Netcracker Technology, a provider of OSS/BSS and service orchestration solutions, announced that, in partnership with Infinera and Juniper Networks, they have released a new Transport SDN solution designed to transform how networks are managed and controlled.

Combining Infinera's expertise in building Intelligent Transport Networks, Juniper's capabilities in IP/MPLS, physical/virtual network functionality and domain orchestration, and NEC/Netcracker's multi-layer control and service orchestration expertise, including NEC's advanced network transport products, the partnership is intended to deliver a compelling new Transport SDN solution.

The integrated solution provides functionality spanning visibility across all IP, optical and microwave domains, including SDN and traditional network environments, optimises network utilisation and automates service provisioning and path restoration.

The solution is designed to equip service providers to implement network transformations that can intelligently adapt to the dynamic requirements of end users, with the ability to provide network slices for specific services end-to-end cross the network. This capability allows providers to accommodate changing traffic patterns and on-demand customer requests and improve quality of services for customers, as well as enabling cost savings by optimising capacity usage.

The solution additionally allows service providers to automate the network service infrastructure, thereby enabling them to focus resources on addressing new revenue opportunities and optimising service costs.

NEC/Netcracker, Infinera and Juniper Networks noted that they joined to demonstrate the combined solution as part of the Optical Interworking Forum (OIF)/Open Networking Foundation (ONF) Transport API project earlier this year. Participants in the project executed a multi-domain path selection and recovery test plan with intra-lab and inter-lab testing across multiple global carrier labs, including those of Verizon and Telefónica.

During the demonstration, NEC/Netcracker's Multilayer SDN Controller used the new Transport API defined by the ONF to communicate with Juniper's NorthStar Controller at Verizon's lab and the Infinera Xceed optical SDN domain controllers at Telefónica's lab. As part of the event, NEC/Netcracker's Service Orchestration solution successfully created and managed Ethernet point-to-point private services across multiple vendor and multiple operator domains.

An Ecosystem Forms to Drive 400G Forward

The next big step on the relentless march forward for Ethernet is 400 Gbit/s. This week's OFC in Los Angeles brought a flurry of activity around 400 Gbit/s and finally we are seeing efforts come together from across a broad ecosystem of module vendors, chip suppliers, test and measurement companies, network equipment suppliers, telecom companies and Internet content providers. As with previous generations, the 400 Gigabit Ethernet will appear in next-generation switches and routers used in high-density cloud data centres and in the core of carrier networks. Meanwhile, work continues on 200 Gbit/s as an interface speed for optical transport, especially in data centre interconnect (DCI) and metro networks, but the building momentum behind 400 Gbit/s seems likely to assure its place as the 'new 100 Gbit/s' as the common denominator for high-speed networks.

While there are always prototype implementations of any new technology years before a standard is ready, this time it looks as if legitimate 400 Gbit/s transceivers will hit the market this year, and switch designs capable of driving this bandwidth may soon follow. The recent Ethernet Switch - Data Centre 5-year forecast report from Dell'Oro predicts that cloud data centres will drive the transition toward 400 Gbit/s by 2019. However, it must first be shown that 400 Gbit/s works as specified, that multi-vendor interoperability is ensured, and that the famous Ethernet price curve is maintained.

Where the technology stands today

At this year's OFC, the first-generation of 400 Gigabit Ethernet pluggable transceiver modules, offered in the MSA based CFP8 form-factor, were shown. Some designs are sampling and some promise to do so soon. Testing tools for 400 Gbit/s developers are on the market and specification work has progressed and MSAs are being completed, while multi-vendor interoperability events are being held, and even the first carrier field trials are occurring.

In February, the Optical Internetworking Forum (OIF) approved an Implementation Agreement (IA) for an optical integrated polarisation multiplexed (PM) quadrature modulator for coherent applications with nominal symbol rates up to 64 Gbaud. The agreement supports the 16QAM modulation format for 400 Gbit/s applications.

In March, a new MSA group released a specification for a new quad small form factor pluggable double density (QSFP-DD), which is a next generation high-density, high-speed pluggable module with a QSFP28-compatible double-density interface. QSFP-DD pluggable modules can quadruple the bandwidth of networking equipment while remaining backwards compatible with existing QSFP form factors used across Ethernet, Fibre Channel and InfiniBand for 40 and 100 Gbit/s network applications. To have significant market impact, the 400 Gbit/s transceiver will need to plug into switches and routers that are 400 Gbit/s ready, and this requires switching silicon ready to support these rates.

AT&T has announced that it completed the first of a multi-phase trial testing 400 Gigabit Ethernet data speeds, using optical gear from Coriant to carry a true 400 Gigabit Ethernet service across a long-distance span of AT&T global backbone from New York to Washington. This demonstrated that AT&T's nationwide software-centric network is 400 Gbit/s-ready. A second phase of the trial will carry 400 Gigabit Ethernet on a single wavelength across its OpenROADM metro network. This phase is expected to use optical gear from Ciena. A third phase is expected to test the first instance of a 400 Gigabit Ethenet open router platform. The 'disaggregated router' platform uses merchant silicon and open source software and is expected to be another industry first.

In a post deadline paper at OFC, researchers at AT&T Labs described the trial, which encompassed an end-to-end 400 Gigabit Ethernet circuit, inclusive of 400 Gbit/s client cards with a CPF8 interface and dual-carrier 16QAM line-side. The trial demonstrated the feasibility of SDN-enabled creation, deletion and re-routing of the 400 Gbit/s service.

In addition, the Ethernet Alliance conducted a live 400 Gbit/s demo carrying traffic from its stand to four additional company booths on the show floor, namely Finisar, Xilinx, Broadcom and Viavi. All the connections were made with LR8 CFP8 transceivers over single mode fibre using 8 x 50 Gbit/s PAM4. Notably, three test equipment companies also participated - Ixia, Spirent and Viavi.

Other 400 Gbit/s announcements from OFC

Broadcom announced a comprehensive portfolio of N x 56 Gbit/s PAM4 PHY devices enabling 50, 100, 200 and 400 Gigabit Ethernet. The new 16 nm N x 56 Gbit/s PAM4 PHY enables low power PAM4 PHYs with high performance DSP-based equalisation to address both copper and optical cabling systems, including multi-mode fibre (MMF) and single-mode fibre (SMF). The PHYs are protocol agnostic to support various interconnect interfaces, including IEEE 802.3bs/cd 50/100/200/400 Gigabit Ethernet for backplane and copper cabling, CDAUI-8 chip-to-module and chip-to-chip, and OIF 56G-LR-PAM-4 for PCB and cabled backplanes.

Inphi introduced the Polaris 16 nm PAM4 DSP PHY ICs, which provide a full bi-directional interface with host ASICs that have 28 GBaud PAM4 and NRZ electrical interfaces and support bridging to 28 Gbaud PAM4 optics. The products also support retiming and gearbox functionality. The line-up includes: Polaris-400G, 8 x 56 Gbit/s PAM4, 16 x 28 Gbit/s NRZ gearbox for CFP8; and Polaris-400G (NG), 8 x 56 Gbit/s, 8 x 56 Gbit/s PAM4 retiming for OSFP/QSFP-DD.

Ixia, Cisco and Foxconn Interconnect Technology (FIT) demonstrated 400 Gigabit Ethernet traffic with QSFP-DD via PAM4 electrical lanes, and Lumentum showcased several 400 Gbit/s transceivers, including QSFP-DD FR4, DR4 and OSFP FR4. The QSFP-DD and OSFP transceivers comply with the recently announced QSFP-DD MSA and OSFP MSA, respectively. Lumentum was an early participant and contributor to both MSAs. The new transceivers use the company’s high-performance EML (electro-absorption modulator laser) technology.

MACOM announced a complete PAM4 technology chipset for 100 Gbit/s data rates over a single wavelength enabling single fibre and four-lane parallel fibre connectivity for 100, 200 and 400 Gigabit Ethernet applications. The chipset features a new TIA, transmit and receive clock and data recovery (CDR) devices and linear EML driver module.

In addition, NeoPhotonics demonstrated a pluggable coherent CFP2-ACO module for 400 Gbit/s over data centre interconnect and metro/regional distances. The ClearLight CFP2-ACO platform uses the company's high bandwidth Class 40 coherent receiver, capable of 64 Gbaud with 16QAM to 64QAM modulation.

Oclaro announced sampling of its 400 Gbit/s CFP8 transceiver for core routers/transport applications. The CFP8 leverages Oclaro's EML laser and receiver technology and is compliant with 400GBASE-LR8 optical and 400GAUI-16 electrical interface specifications under final standardisation by the IEEE 802.3bs task force. Oclaro expects commercial production in the second half of 2017.

Finally, Viavi Solutions showcased its ONT-600 400 Gbit/s test platform, which aims to accelerate 400G deployment, from the early stages of developing and validating CFP8 FR8/LR8 modules to fully comprehensive Ethernet performance needed for system level and service validation. The company said it has recently released several applications, including enhanced FEC testing, enabling validation of performance of 400 Gbit/s elements against IEEE P802.3 bs (draft) FEC. Viavi also announced new advanced error analysis applications: all types of errors including bursts, individual bit errors and slips are characterized to quickly establish the root cause.

Watch for bigger switching silicon

One further area to keep an eye on is the progression of terabit-class switching silicon. Broadcom dominates in switching silicon but several start-ups are looking at this next step function in Ethernet bandwidth as the ideal opportunity to make a market entrance.  One such upstart is San Jose-based Innovium, which has unveiled its 12.8 Tbit/s TERALYNX scalable Ethernet silicon for data centre switches. The design is powerful enough to deliver 128 ports of 100 Gigabit Ethernet, 64 ports of 200 Gigabit Ethernet or 32 ports of 400 Gigabit Ethernet in a single device. Innovium, in partnership with Inphi, has already produced a single switch chip-based reference design for a platform supporting 12.8 Tbit/s (128 x 100 Gigabit Ethernet) QSFP28 deployments. The reference design uses Innovium's 12.8Tbit/s TERALYNX Ethernet switch silicon and Inphi's PAM4 chipset. Versions with 400 Gbit/s ports should be just over the horizon.

Picometrix to supply 100G Coherent Receivers to Chinese Vendor

Luna Innovations, a developer and supplier of fibre optic sensing and T&M products, announced that its Picometrix division has entered into a vendor managed inventory (VMI) agreement with a major Chinese provider of telecoms equipment and network solutions.

Under the agreement, Picometrix's technology will be more closely integrated into the customer's supply chain and manufacturing processes. As part of the deal, Picometrix will maintain in Hong Kong a dedicated inventory of 100 Gbit/s integrated coherent receivers and other future approved products that the customer will be able to incorporate into its manufacturing operation on a just-in-time basis.

Following the execution of the new VMI agreement, Picometrix has received an order for the supply of coherent receivers for 100 Gbit/s optical transport network equipment. The order is valued at approximately $1.4 million and scheduled to be delivered by June 2017.

Under the agreement, Picometrix expects to supply both its first generation CR-100D product and its next generation, Gen 2, CR-100F coherent receivers. The CR-100F device is the company's latest generation 100 Gbit/s coherent receiver that is compliant with the Optical Internetworking Forum (OIF) Implementation Agreement (IA) for integrated dual polarisation micro-intradyne coherent receivers (ICRs).

Picometrix noted that the Gen 2 CR-100F product is approximately one-quarter the size of its first generation CR-100D and also offers additional features including signal detect and a variable optical attenuator. The customer will deploy the CR-100F for long-haul and metro applications as an upgrade to support increasing bandwidth demand.

Previously, in October 2016 Luna Innovations announced that Picometrix had received a $2.8 million follow-on order from a leading telecoms company for its 100 Gbit/s ICR for applications in long-haul and metro networks.

OIF Completes SDN Transport Application Programming Interface (T-API) Testing

The Optical Internetworking Forum (OIF) conducted a six-week long global testing of the Transport Application Programming Interface (T-API) standard from the Open Networking Foundation (ONF) with intra-lab and inter-lab testing across five carrier labs: China Telecom, China Unicom, SK Telecom, Telefonica and Verizon.

“As operators move from SDN PoCs and lab trials into commercial deployments, lack of interoperability between the SDN controllers and the orchestration layer above has quickly become the biggest technical barrier for many operators,” said Sterling Perrin, principal analyst, Heavy Reading. “Building a standardized northbound interface and successfully testing interoperability across different vendors and different networks – as the OIF has demonstrated – is a major step forward in addressing the northbound interface challenge and bringing SDN architectures to wide-scale commercial use.”

Thes testing included multi-domain orchestration of services delivered through Ethernet, OTN and optical switching. Carriers and vendors demonstrated how Virtual Network Functions (VNF) and SDN configured connectivity are combined to deliver service life cycle management.

Participating vendors include ADVA Optical Networking, Ciena, Coriant, Huawei Technologies Co., Ltd., Infinera, Juniper Networks, NEC Corporation, Sedona Systems, and SM Optics. Consulting carriers include Orange and TELUS. Academic and/or research institution participants include China Academy of Telecommunication Research (CATR) and Centre Tecnològic de Telecomunicacions de Catalunya (CTTC).

Participants also submitted a proof of concept demo proposal to ETSI NFV called “Mapping ETSI-NFV onto Multi-Vendor, Multi-Domain Transport SDN”.

A technical white paper on the demonstration is available to download.

OIF Approves Polarized Multiplexed Quadrature Modulator for 400G

The Optical Internetworking Forum (OIF) approved an Implementation Agreement (IA) for an optical integrated Polarization Multiplexed (PM) quadrature modulator for coherent applications with nominal symbol rates up to 64GBaud. The agreement supports the 16QAM modulation format for 400G applications.

“As we go to higher data rates, we need higher performing optical components that maintain a reasonable level of complexity,” said Karl Gass of Qorvo and the OIF’s PLL Working Group – Optical Vice Chair. “These components are targeted for 400G applications. RF bandwidth is the highest priority for this project.”

The forum members also started the CEI-112G in MCM project to support interconnect within Multi-Chip-Modules (MCMs). In addition to the CEI-112G-VSR specification that is being developed, there is a need to support high rate interconnect amongst large logic devices as well as to small driver devices within an MCM.

Members have also started a maintenance project to produce amendments to the User Network Interface (UNI) 2.0 and External Network to Network Interface (E-NNI) 2.0 specification documenting the extensions for support of OTN rates higher than 100G. Adding these extensions to UNI 2.0 and E-NNI 2.0 will facilitate vendor interoperability. The project seeks to assist the IETF as it develops the required routing and signaling extension by providing a description of the Byond100G data-plane and the operations to be controlled by GMPLS.

OIF Begins Work on Two FlexE Projects

The Optical Internetworking Forum has started work on two new FlexE projects.

“The datacenter and communications industries are demanding a solution for flexible deployment and provisioning of Ethernet bandwidth,” said Scott Irwin of MoSys and the OIF’s Physical and Link Layer (PLL) Working Group protocol vice chair. “Building on its first generation of FlexE, the OIF has started a new project to support the next generation of Ethernet PHY rates currently under development within the IEEE 802.3 Working Group. Because of the large industry interest in FlexE, the OIF is also hosting a workshop on the topic which allows non-members to learn about the work first hand.”

The FlexE 1.0 implementation agreement, completed in March of this year, provides a mechanism to map one or more FlexE clients over a group of 100 Gb/s Ethernet PHYs. The client rates supported are 10G, 40G, and n×25G. The new FlexE 2.0 project will add the ability to create FlexE groups of 200 Gb/s and 400 Gb/s Ethernet PHYs and to consider several other feature additions.

FlexE 1.0 and ongoing revision enable 802.1 LLDP over management channels for FlexE Connectivity Verification. However, FlexE capabilities discovery is still required to facilitate the setup of FlexE Group(s) and Clients. The new FlexE Neighbor Discovery project will introduce some OIF organizational specific FlexE Extension to LLDP for FlexE capabilities discovery.

The OIF will host a workshop titled, FlexE Today and Tomorrow, in San Jose on January 20th.

OIF Commences Work on Four New Project

Following its Q4 meeting this month in Auckland, New Zealand, The Optical Internetworking Forum announced four new projects:

  • 400ZR Interoperability Project -- will develop an implementation agreement for 400G ZR and short-reach DWDM multi-vendor interoperability.  It is relevant for router-to-router interconnect use cases and is targeted at (passive) single channel and amplified DWDM applications with distances up to 120 km. This project should ensure a cost-effective and long-term relevant implementation using single-carrier 400G, coherent detection and advanced DSP/FEC algorithms.  
  • Common ACO Electrical I/O Project -- will define the ACO electrical I/O independent of the choice of form factor and optical carrier count for 45 Gbaud and 64 Gbaud per-carrier applications. This project would build upon the success of the CFP2-ACO but is form factor agnostic so that it could be applied to multiple applications such as  CFP4, CFP8, QSFP, micro QSFP and OFSP.
  • Coherent Modem Management Interface Project -- members have requested that the industry combine the coherent modem management interface specifications [4"x5" LH MSA, CFP2-ACO, CFP2-DCO, Flex-Coherent, etc.] into a standalone document.  OIF leadership, working in conjunction with the CFP MSA group, is inviting companies to participate in creating a complementary Normative document.
  • High Baud Rate Coherent Modulation Function Project -- will define a small form factor component implementation agreement that combines the high baud-rate PMQ (HB-PMQ) modulator plus the RF drive functions into a single component. This new component will be used in conjunction with a high baud Integrated Coherent Receiver (ICR), a micro Integrable Tunable Laser Assembly (ITLA) and a coherent DSP, to implement a high performance coherent modem.

“The OIF continues to work with other standards bodies and the industry to identify a wide range of technology needs that cross the entire optical and electrical ecosystem,” said Karl Gass of Qorvo and the OIF’s Physical Link Layer working group optical vice-chair.  “The OIF remains committed to providing technology direction that provides a path to interoperability in a pre-competitive environment. The projects started during the Q4 meeting demonstrate the OIF’s  commitment to work with other standards bodies in the industry.”

In addition, OIF announced the following election results: Dave Brown of Nokia was re-elected to the Board for a two-year term and appointed as president.  Re-elected to one-year terms were Junjie Li of China Telecom and Dave Stauffer of Kandou Bus. Stauffer will continue to serve as secretary/treasurer. Jonathan Sadler of Coriant and Nathan Tracy of TE Connectivity were elected to the board for two-year terms.  Tracy was appointed as vice president of marketing. Tom Issenhuth of Microsoft was appointed as vice president and Ian Betty of Ciena continues to serve on the Board.

Newly elected were Klaus-Holger Otto of Nokia as Technical Committee chair, Ed Frlan of Semtech as Technical Committee vice chair and Jeffery Maki of Juniper Networks as chair of Physical Layer User Group Working Group.

Brian Holden of Kandou Bus, Market Awareness and Education Committee co-chair, Physical and Link Layer; and Lyndon Ong of Ciena, MA&E Committee co-chair, Networking were both re-elected.

OIF Begis Work on IC-TROSA and CFP2-Digital Coherent Optics Project

The Optical Internetworking Forum’s (OIF) has begun work on two optical interface projects:

the IC-TROSA project would enable manufacturers to have a higher level of integration for transmit and receive optical components. Integrated Coherent Transmitter-Receiver Optical Subassembly (IC-TROSA) is the evolutionary step that combines Polarization Multiplexed Quadrature (PMQ) Transmitter (Tx) and Integrated Coherent Receiver (ICR) components to create a single integrated optics package.  The optical sub-assembly that supports high-bandwidth and high-order QAM operations is suited for data center interconnect, metro and long-haul applications. As module sizes decrease, current coherent optics components need similar size reductions to enable next generation multi-terabit switches, line cards, and transport. Density requirements for next-gen line cards, front-pluggable and future on-board 400G+ optical modules are driving the need for further integration and miniaturization.

the CFP2-Digital Coherent Optics (DCO) project will work with other standards bodies to implement coherent modulations formats in CFP modules. The OIF’s CFP2-DCO project includes a way to build address management interface and identify registers necessary to talk to the DSP located in the module, specific to coherent modulation techniques. The CFP2-DCO is intended to be used for 100G, 200G or 400G applications for metro, long-haul and data center interconnections and it can support different formats such as DP-QPSK and DP-xQAM.

“The IC-TROSA project tackles much more than just a simple size reduction,” said Karl Gass of Qorvo and the OIF’s Physical and Link Layer (PLL) Working Group – Optical vice chair.  “It addresses optical packaging in a way that isn’t done in high volumes today. We want to come to industry consensus in this pre-competitive environment.”
