OIF launches higher baud rate coherent driver modulator project

The OIF has begun a new project to develop a higher baud rate coherent driver modulator.

The “Higher Baud Rate Coherent Driver Modulator” project will define a new version of the Coherent Driver Modulator supporting at least 96 Gbaud for the low modem implementation penalty segment of the coherent market for single optical carrier line rates beyond 400 Gbit/s. Designed for higher data rates and longer reach and optimized for performance, this project is the next generation of the High Bandwidth Coherent Driver Modulator (HB-CDM) Implementation Agreement (IA) published last year.

Following this year’s OIF Q319 Technical and MA&E Committees Meeting in Montreal, OIF also launched work on a white paper detailing low-rate service multiplexing using FlexE and 400ZR. The whitepaper seeks to eliminate ambiguity and provide clarification on how 400ZR should be leveraged in multiplexing applications. Various network operators are looking for a multiplexing scheme to support lower-rate Ethernet clients (e.g. 4x100GE) into a 400ZR coherent line. This technical white paper will educate the market on how FlexE can be used to aggregate low-rate Ethernet services (e.g. 4x100GE) into 400ZR interfaces.

Andrew Schmitt, founder and directing analyst, Cignal AI gave member attendees a brief overview of emerging pluggable coherent technologies and the opportunity this new market presents and had the opportunity to speak with members about current and upcoming OIF work.

“It’s clear that OIF is not resting after a successful effort to standardize 400ZR, proven by the launch of two new projects at the recent Q3 meeting,” said Schmitt. “Also, as interest in pluggable coherent solutions grows, it is good to see OIF soliciting feedback from additional network operators in order to shape requirements for next generation standards.”

OIF releases CFP2-DCO and HB-CDM specs

OIF completed two new Implementation Agreements (IAs) — the CFP2-Digital Coherent Optics Module (CFP2-DCO) and High Bandwidth- Coherent Driver Modulator (HB-CDM).

  • CFP2-DCO - defines the additional information needed in order to implement the DCO function in the CFP2 module. The CFP2-DCO module contains all the required functions to perform dual polarization coherent optical signaling. The module can also provide different bitrates such as 100G/200G/300G/400G and support more modulation formats.
  • HB-CDM - targets modulation and data-rate agnostic coherent applications having nominal symbol rates up to 64 Gbaud. It defines a small form factor electro-optic component that integrates the HB-Polarization Multiplexed-Quadrature (HB-PMQ) modulator plus the RF drive functions for the high baud-rate and low modem implementation penalty segment of the coherent market. Additionally, the IA identifies and specifies the common features and properties of coherent transmitters to enable them to broadly meet the needs of current and future coherent systems.

“As a member-driven organization, OIF’s work is based on our members’ needs. The CFP2-DCO IA is in direct response to feedback from a network operator that needed an IA to fill an interoperability gap in their network,” said Karl Gass, OIF, PLL Working Group – Optical Vice Chair. “The HB-CDM IA addresses a performance need by creating a component that can be used for much higher performance links.”

OIF and Ethernet Alliance run FlexE traffic over 400G

At OFC in San Diego, OIF and the Ethernet Alliance are running Flex Ethernet (FlexE) traffic sent over three bonded and subrated 100 GbE interfaces streaming over the Ethernet Alliance 400 GbE network. The demo, which provides a live interconnection between the OIF and Ethernet Alliance booths on the show floor, is designed to showcase the Ethernet Alliance’s IEEE 802.3bs 400 Gbps network and OIF’s FlexE 2.0 Implementation Agreement (IA).

“The Ethernet Alliance’s 400 GbE network over the OFC exhibit floor is the perfect setting to illustrate the real-world features and capabilities of the OIF FlexE 2.0 IA that allows network operators to tailor their traffic while still leveraging Ethernet,” according to Nathan Tracy, OIF’s President and Technologist at TE Connectivity. “The Ethernet Alliance’s deployment of the 400 GbE network at OFC combined with OIF’s FlexE demonstration illustrates the coincident availability of these new technologies.”

“We’re pleased to be able to make our 400 GbE network available to the OIF for this demonstration at OFC,” said Ethernet Alliance chairman John D’Ambrosia. “We applaud the OIF for its work in leveraging 100 GbE and 400 GbE in its FlexE 2.0 implementation agreement. Their efforts will increase the capabilities of these solutions to help address the market needs of the Next Ethernet Era.“

The member companies participating in the OIF demo include Amphenol, Cisco, Credo Semiconductor (HK) LTD, Finisar, Inphi, Juniper Networks, Keysight Technologies, Molex, Spirent Communications, TE Connectivity, VIAVI Solutions, Xilinx and YAMAICHI ELECTRONICS.

Rhe Ethernet Alliance’s OFC 2019 demo incorporates equipment and solutions from 21 different companies: Amphenol; Anritsu; Arista Networks; Cisco; Credo Semiconductor; EXFO; Finisar; Intel; Ixia / Keysight Technologies; Juniper Networks; Lumentum; Nexans S.A.; Panduit; Source Photonics; Spectra7 Microsystems; Spirent Communications; TE Connectivity; Tektronix; Teledyne LeCroy; VIAVI and Xilinx, Inc.

OIF to provide CEI-112G project update at DesignCon

At next week's DesignCon conference in Santa Clara, California,

The panel, called “112-Gbps Electrical Interface: An OIF Update on CEI-112G,” is scheduled for Thursday, January 31 at 3:45 pm (local).

Since 2000, OIF has defined Interoperability Agreements (IA)s for electrical interconnects known as CEI. CEI is a clause-based document that defines implementation details for interoperable electrical channels initially issued for 6 Gbps, then 11, 28, and 56 and includes definitions for multiple channel implementation topologies and will soon include 112 Gbps clauses. In August of 2016, OIF announced the first CEI-112G project in an overall effort that has now expanded to five projects.

“Previous CEI development has been highly influential and has been adopted, influenced or adapted by many other high-speed interconnect specifications throughout the industry,” said Tracy. “Given that the CEI-112G generation of high-speed transmitters, receivers and channels will be challenging to define, implement and measure, this panel will provide guidance to where the industry is headed and what the key challenge points are likely to be.”

OIF Launches FlexE 2.1 Project

OIF has launched the FlexE 2.1 project, which covers FlexE over 50Gbe PHY applications. It also adds an extension to the recently released FlexE 2.0 Interoperability Agreement (IA).

FlexE 2.1 will specify a 50G FlexE frame and multiplexing format and will address Flex Ethernet (FlexE) applications with lower bandwidth needs and provide an implementation foundation for applications including the access layer of the future 5G mobile network. This new 50GbE support will extend the existing support for 100, 200 and 400GE in the just published FlexE 2.0 IA.

OIF expects possible large volume applications for channelization (5Gb/s granularity for minimum 10G clients) and bonding of 50GE PHYs in the future access layer/metro edge (based on IPRAN/PTN) of the 5G mobile backhaul network, FlexE implementation logic will be critical.

“There is continued demand by data center and network operators for a solution for flexible deployment and provisioning of Ethernet bandwidth,” said Dave Ofelt, Juniper Networks and OIF Physical and Link Layer (PLL) Working Group – Protocol Vice Chair. “Building on OIF’s great work for FlexE and FlexE 2.0, this new FlexE 2.1 project will ultimately result in a single IA that adds n×50Gb/s support to FlexE 2.0, along with other possible feature enhancements.”

In addition, OIF announced the following election results for its Board of Directors:

  • Nathan Tracy, TE Connectivity, was re-elected to the Board and appointed as President
  • Tad Hofmeister, Google, was appointed as Vice President
  • Martin Bouda, Fujitsu, was re-elected to the Board and appointed as Secretary/Treasurer
  • Mike Li, Intel, was newly elected to the Board
  • Cathy Liu, Broadcom Inc., was re-elected to the Board
  • Gary Nicholl, Cisco, was newly elected to the Board
  • Ian Betty, Ciena, continues to serve on the Board

OIF project tackles Requirements for Integrated Packet Optical SDN

The OIF announced its newest project — “Requirements for Integrated Packet Optical SDN.” The goal is to outline requirements for a multi-layer SDN reference architecture as a use case for packet optical transport networks.

The project will generate functional requirements, a reference architecture and use cases for packet/optical networks guided by the vision to enable agile, open network solutions that simplify operations and optimize resource utilization.

“Most of the existing SDN standards work, including OIF’s recent SDN Transport Application Programming Interface (T-API) multi-vendor interoperability demo, addresses the technical details,” said Junjie Li of China Telecom and OIF Network Operator Working Group Chair. “However, it is critical to also work across layers and build a standardized universal open framework at the solution level that will normalize architecture, interfaces and behaviors to advance the industry as a whole.”

OIF completes Flex Ethernet and Common ACO Electrical I/O agreements

The OIF announced three Interoperability Agreements (IAs) aimed at expanded interoperability of Flex Ethernet and increased data rates. These include:

FlexE 2.0 -- initiated in 2016, the FlexE 2.0 project enables equipment to support new Ethernet connection types and FlexE allows network providers and operators to utilize optical transport network bandwidth in more flexible ways. FlexE can deterministically utilize the entire aggregated link, creating a more efficient alternative to the traditional IEEE 802.3ad or IEEE 802.1-based Link Aggregation (LAG) solutions which often can only utilize 70-80% of the available bandwidth. Key features of the FlexE 2.0 project include adding support for FlexE groups composed of 200GBASE-R and 400GBASE-R PHYs, in addition to groups composed of 100GBASE-R PHYs, and adding an option for the support of time and frequency synchronization at the FlexE group level.

FlexE Neighbor Discovery -- this project recognizes that FlexE capability discovery is still required to facilitate the setup of FlexE groups and clients. The project introduced some extensions to the Link Layer Discovery Protocol (LLDP) for FlexE capability discovery. It enables remote FlexE PHY and deskew capability discovery, PHY connectivity discovery and verifications, and FlexE Group subgroup integrity verification.

Common ACO Electrical I/O Project -- this implementation agreement follows the success of the CFP2-ACO optical transceiver implementation agreement but is form factor agnostic, so it also benefits analog coherent modules based on such form factors as CFP4, CFP8, QSFP, microQSFP, QSFP-DD and OSFP. The project defines 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.

“The completion of these projects reinforces OIF’s commitment to provide the industry with the flexibility and increased bandwidth solutions combined with increased data speeds it requires to keep up with market demands and drive solutions that enable the next generation of networks,” explained Dave Stauffer of Kandou Bus and OIF’s Physical and Link Layer (PLL) Working Group Chair.

OIF validates Transport Application Programming Interface (T-API) 2.0

The Optical Internetworking Forum's Transport Application Programming Interface (T-API) 2.0 is market ready, following a six week, multi-vendor interoperability demonstration. The results of the interoperability test are reported in a new whitepaper published by the OIF.

The multi-vendor demo led by four network operator labs included lab-deployed and cloud-deployed systems testing new dynamic behavior use cases and deployment scenarios. The demo also incorporated service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines extensions to T-API in support of Carrier Ethernet services.

Participating network operators were CenturyLink, China Telecom, SK Telecom and Telefónica and vendors included ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) was a participating academic institution and TELUS Communications participated as a consulting network operator.

Key findings detailed in the whitepaper:

  • Open Networking Foundation (ONF) T-API 2.0 specifications have addressed the main issues identified in the OIF’s 2016 testing and provide a basis for real-time orchestration of on-demand connectivity setup, control and monitoring across diverse multi-layer, multi-vendor, multi-domain carrier networks
  • Additional scaling and performance enhancements will need to be addressed as T-API is deployed in real networks, such as refinements to the model, greater detail in error codes to improve debugging properties, and potential implementation options such as a separate server for notifications of network events
  • The API allows for some variability in the use of topology abstraction depending on business requirements and technology; documentation of supplementary examples for topology abstraction will help application and orchestration software developers.

http://www.oiforum.com/documents/oif-2018-sdn-t-api-interop-demo-white-paper/



“Standardized and open SDN APIs reduce complexity in intra and inter-domain operations, allowing us to provide more diverse services to our customers in less time,” said Park Jin-hyo, EVP of ICT R&D Center at SK Telecom. “After successfully completing the test trial, SK Telecom will keep engaging in 5G transport network and service development by opening APIs and transforming the current infrastructure into Network-as-a-Service (NaaS) Platform.”

Layer 1 Transport API interoperability demo -- MEF, ONF, and OIF



The recently concluded MEF-ONF-OIF interoperability demo that focused on the Software-Defined Networking (SDN) Transport Application Programming Interface (T-API).

NEC's Karthik Sethuraman and Centurylink's Jack Pugaczewski provide an overview of the demo. A proof-of-concept (PoC) on this topic will be presented at #MEF18.

Optical Internetworking Forum tests SDN transport API

Optical Internetworking Forum (OIF), in collaboration with MEF, successfully concluded its 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) multi-vendor interoperability demonstration.


The multi-vendor demo led by four network operator labs included lab deployed and cloud deployed systems testing new dynamic behavior use cases and deployment scenarios. The demo also incorporated service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines extensions to T-API in support of Carrier Ethernet services.

“The OIF SDN Interoperability demonstration has successfully brought together carriers, vendors and integrators with a common goal of moving to an open API (TAPI),” said Jack Pugaczewski, Distinguished Architect, CenturyLink. “T-API is a key enabler for providing automated service fulfillment and assurance. We have tested the Connectivity, Topology and Notification software patterns that T-API provides. Common APIs reduce design, development and deployment cycles for all involved, thus getting to market faster and realizing the financial benefits of automation.”

Participating network operators were CenturyLink, China Telecom, SK Telecom and Telefónica and vendors included ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) was a participating academic institution and TELUS Communications participated as a consulting network operator.

“The OIF’s goal for interop events is to improve the quality and clarity of specifications being tested,” explained Jonathan Sadler, OIF VP and Networking & Operations Interoperability Working Group Chair. “As the tests were performed, we noted possible points for misunderstanding and places where the specifications may be enhanced. These results will be liaised to ONF and MEF for review at future meetings.”

OIF initiates CEI-112G-XSR project

The OIF has launched a CEI-112G-XSR project for Die-to-Die (D2D) and Die-to-Optical Engine (D2OE) Common Electrical Interface, which will enable intra-package interconnects to optical engines or between dies with high throughput density and low normalized power operating in the data rate range of 72-116 Gbps with a reach up to 50 mm.

In addition to the already existing CEI-112G-MCM OIF project, which is dedicated to wide, high bandwidth CMOS-to-CMOS interconnects, the new CEI-112G-XSR project proposes to support technology mix, in particular CMOS-to-SiGe (Silicon Germanium), which is frequently used to build optical engines. System-in-package (SIP) leads to a requirement of supporting up to 50 mm trace length between the multiple chips on a common (organic) package substrate.

The working group for the CEI-112G-XSR project has identified the following benefits for OIF members:

  • allow lower normalized power, double shoreline throughput density and provide a multi-source 72-116 Gbps D2D and D2OE electrical I/O interface. This will enhance the integration, normalized power reduction, and cost reduction for integrated OE, multiple-die SIPs.
  • enable 1 to N lanes of 72-116 Gbps electrical I/Os (e.g. on ASIC/FPGA/OE).

“We jointly designed this project to address the problem of integrating multiple dies, including driver devices for optical engines on non-CMOS technologies, onto a common substrate within a large multi-chip-package design. Supporting this mix of technology allows combining the high logic density of CMOS devices with the high drive strength of analog components,” explained Klaus-Holger Otto of Nokia and OIF Technical Committee Chair.

OIF plans SDN Transport API interoperability demo presentations

The OIF (Optical Internetworking Forum) will conduct several public read-out events to present the results of the 2018 Software-Defined Networking (SDN) Transport Application Programming Interface (T-API) interoperability demonstration.

This year’s demo, in collaboration with MEF, is focused on accelerating the commercialization of Transport SDN through validating the industry-leading T-API 2.0 northbound interface (NBI) from the Open Networking Foundation (ONF). The multi-vendor demo includes testing new dynamic behavior use cases and deployment scenarios by CenturyLink, China Telecom, SK Telecom and Telefónica. Participating vendors include ADVA, Coriant, Infinera, NEC/Netcracker, Nokia and SM Optics. Centre Tecnològic Telecomunicacions Catalunya is the participating academic and/or research institution and TELUS Communications is participating as a consulting network operator.

The demo incorporates service provisioning scenarios at the LSO Presto reference point in the MEF LSO architecture, using the MEF NRP Interface Profile Specification (MEF 60), which defines T-API extensions in support of Carrier Ethernet services.

“The OIF multi-vendor interop testing is particularly important to Telefónica’s network transformation. We are anxious to validate T-API as the standard NBI for Transport SDN and announce the results in June,” said Juan Pedro Fernández Palacios, Telefónica.

The results of the demo will be presented during a featured workshop and keynote presentation at NGON & DCI Europe 2018 conference in Nice, France.

Private read-outs will also be conducted by CenturyLink (July 10 in Denver) and China Telecom in Beijing (July 19).

OIF hosts Interoperability demos of FlexE, 56G PAM4, 112G per lane

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.”

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.

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.
