AT&T Conducts 400G Field Trial

AT&T completed the first of a multi-phase trial testing 400 gigabit Ethernet data speeds. This first phase used optical gear from Coriant to carry a true 400GbE service across a long-distance span of AT&T global backbone from New York to Washington, demonstrating that AT&T’s nationwide software-centric network is 400G-ready.

A second phase of the trial will carry a 400GbE on a single 400G wavelength across AT&T’s 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 400GbE open router platform. The “disaggregated router” platform uses merchant silicon and open source software – and this is expected to be another industry first.

“Our approach to roll out the next generation of Ethernet speeds is working. We continue to see enormous data growth on our network, fueled by video. And this will help with that growth,” said Rick Hubbard, senior vice president, AT&T Network Product Management.

In a post deadline paper at OFC, researchers at AT&T Labs described the trial, which encompassed an end-to-end 400G Ethernet circuit, inclusive of 400GbE 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 400G service.

Facebook shows its progress with Open Compute Project

The latest instalment of the annual Open Compute Project (OCP) Summit, which was held March 8-9 in Silicon Valley, brought new open source designs for next-generation data centres. It is six years since Facebook launched OCP and it has grown into quite an institution. Membership in the group has doubled over the past year to 195 companies and it is clear that OCP is having an impact in adjacent sectors such as enterprise storage and telecom infrastructure gear.

The OCP was never intended to be a traditional standards organisation, serving more as a public forum in which Facebook, Microsoft and potentially other big buyers of data centre equipment can share their engineering designs with the industry. The hyper-scale cloud market, which also includes Amazon Web Services, Google, Alibaba and potentially others such as IBM and Tencent, are where the growth is at. IDC, in its Worldwide Quarterly Cloud IT Infrastructure Tracker, estimates total spending on IT infrastructure products (server, enterprise storage and Ethernet switches) for deployment in cloud environments will increase by 18% in 2017 to reach $44.2 billion. Of this, IDC estimates that 61% of spending will be by public cloud data centres, while off-premises private cloud environments constitute 15% of spending.

It is clear from previous disclosures that all Facebook data centres have adopted the OCP architecture, including its primary facilities in Prineville (Oregon), Forest City (North Carolina), Altoona (Iowa) and Luleå (Sweden). Meanwhile, the newest Facebook data centres, under construction in Fort Worth (Texas) and Clonee, Ireland are pushing OCP boundaries even further in terms of energy efficiency.

Facebook's ambitions famously extend to connecting all people on the planet and it has already passed the billion monthly user milestone for both its mobile and web platforms. The latest metrics indicate that Facebook is delivering 100 million hours of video content every day to its users; 95+ million photos and videos are shared on Instagram on a daily basis; and 400 million people now use Messenger for voice and video chat on a routine basis.

At this year's OCP Summit, Facebook is rolling out refreshed designs for all of its 'vanity-free' servers, each optimised for a particular workload type, and Facebook engineers can choose to run their applications on any of the supported server types. Highlights of the new designs include:

·         Bryce Canyon, a very high-density storage server for photos and videos that features a 20% higher hard disk drive density and a 4x increase in compute capability over its predecessor, Honey Badger.

·         Yosemite v2, a compute server that features 'hot' service, meaning servers do not need to be powered down when the sled is pulled out of the chassis in order for components to be serviced.

·         Tioga Pass, a compute server with dual-socket motherboards and more IO bandwidth (i.e. more bandwidth to flash, network cards and GPUs) than its predecessor, Leopard, enabling larger memory configurations and faster compute time.

·         Big Basin, a server designed for artificial intelligence (AI) and machine learning, optimised for image processing and training neural networks. Compared to its predecessor, Big Basin can train machine learning models that are 30% larger due to greater arithmetical throughput and by implementing more memory (12 to 16 Gbytes).

Facebook currently has web server capacity to deliver 7.5 quadrillion instructions per second and its 10-year roadmap for data centre infrastructure, also highlighted at the OCP Summit, predicts that AI and machine learning will be applied to a wide range of applications hosted on the Facebook platform. Photos and videos uploaded to any of the Facebook services will routinely go through machine-based image recognition and to handle this load Facebook is pursuing additional OCP designs that bring fast storage capabilities closer to its compute resources. It will leverage silicon photonics to provide fast connectivity between resources inside its hyper-scale data centres and new open source models designed to speed innovation in both hardware and software.

Ciena Opens WaveLogic to Lumentum, NeoPhotonics and Oclaro

Ciena announced it is extending the market reach of its WaveLogic coherent modem technology by making it available to a number of industry participants, with optical component companies Lumentum, NeoPhotonics and Oclaro to leverage WaveLogic technology to develop coherent optical modules for a range of applications.

Additionally, each of the companies will join an ecosystem that will focus on standards-based product development, designed to provide customer choice in the emerging 400 Gbit/s pluggable market, which is being driven by increasing data centre interconnect (DCI) requirements.

Ciena stated that while retaining its intellectual property rights, through the initiative it will provide its WaveLogic Ai chipset to Lumentum, NeoPhotonics and Oclaro. The partners will each be responsible for the manufacture, sale and distribution of Ciena-designed 5 x 7 coherent modules based on a combination of the WaveLogic technology and electro-optics components.

In addition, under the agreement the partner companies will contribute to the ongoing development of 400 Gbit/s pluggable technologies and the establishing of specifications for adoption by relevant industry forums and standards-setting bodies. Ciena intends to invest in further developing coherent DSP technology, which its partners will then be able to utilise in the development of 400 Gbit/s pluggable modem solutions for hardware and systems vendors.

Lumentum, NeoPhotonics and Oclaro will also support the creation of a roadmap for future generations of coherent optical modules based on Ciena's WaveLogic technology.

Coriant Unveils Aware Toolkit for Real-time Optical Performance, Control Capability

Coriant has announced the introduction of Coriant Aware Technology, an new software-enabled toolkit designed to enhance the value of dynamic optical networks via sophisticated real-time performance awareness and control functionality.

In a live demonstration at OFC 2017, Coriant will showcase how the Aware technology can be used to enable faster and simpler new wavelength planning and provisioning, increased reach and capacity and improved service availability.

Coriant noted that existing networks suffer from limitations that can increase costs, increase wavelength activation times, limit reach and reduce efficiency, with these limitations in part due to planning tools that do not have real-time data from the optical network, as well as coherent receivers that are unable to measure OSNR and NMS, SDN and ASON/GMPLS implementations that lack the optical models of offline planning tools. In addition, the adoption of SDN and flexi-rate interfaces will further emphasise these limitations.

The new Coriant Aware technology is designed to correlate, analyse and act upon real-time data by applying concepts already used for the Internet of Things (IoT) and help to address these limitations, as well as help operators reduce capex and opex.

Coriant noted that residual margin in a network is affected both by OSNR and linear and non-linear impairments, so that accurately assessing residual margin means determining the impact of all three factors. For example, while current coherent receivers may be able to measure linear effects such as CD, PMD and PDL, they cannot measure the impact on signal quality, nor accurately measure OSNR or the effect of nonlinear penalties.

To address these issues, Aware technology features two components: the Optical Performance Engine (OPE) and Margin Processing Engine (MPE).

Optical Performance Engine

OPE is designed to combine the accuracy of an offline planning tool with the real-time speed needed for wavelength activation, Layer 0 restoration, and other optical use cases, with real-time performance enabled by simplifying the mathematical operations.

The OPE responds to path validation requests from the path computation function within the NMS, SDN or ASON/GMPLS control plane. With optical models that incorporate both linear and nonlinear effects, the OPE generates valid options for each requested path, including modulation types, baud rates, FECs, frequencies and power levels to allow the optimum options, including flexi-rate interface settings and super-channels, to be selected.

Margin Processing Engine

MPE is designed to enable operators to accurately estimate residual margin by collecting performance monitoring data from across the network, including coherent receivers and per-channel power monitoring capabilities of the network elements. It then processes this data in real-time to distinguish OSNR from signal degradation due to linear and nonlinear impairments, providing accurate, real-time residual margin values for each channel.

Additionally, MPE is able to provide this without the need for next-generation DSPs, allowing use with installed coherent interfaces.

Key capabilities enabled by Coriant Aware technology include:

1. Increased transmission reach and capacity by reducing or eliminating margin stacking and optimising power levels.

2. Faster wavelength service activation through reducing the provisioning steps required and the boundaries between planning and management systems.

3. Higher availability via support for SDN or ASON/GMPLS restoration, enabling a reduction in margin requirements for temporary restoration paths and pro-active downtime prevention.

4. Allows operators to use margin as extra capacity that can be provided to customers.

Coriant Aware technology will be introduced in phases, with initial OPE functionality due to be available for trials beginning in the second quarter of 2017.

Oclaro Unveils I-Temp Transceivers for 5G fronthaul, Samples 400G

Oclaro announced the introduction of two new industrial temperature (I-temp) transceivers designed to drive the market transition to 5G wireless fronthaul systems and sampling of its 400 Gbit/s CFP8 transceiver for core routers/transport applications.

I-temp transceivers

Oclaro's new I-temp transceivers are designed to provide customers with the flexibility to choose either a 10 Gbit/s TSFP+ I-temp that can fit a WDM fronthaul system into a next generation 5G wireless network, or a 25 Gbit/s SFP28 LR I-temp that significantly increases data capacity and offers industry-leading low power consumption.

The TSFP+ is Oclaro's latest product to include I-temp and follows the company's 10 Gbit/s TSFP+ C-temp and E-temp devices, which are already shipping. The TSFP+ is vertically integrated based on Oclaro's in-house ILMZ chip and custom-designed TOSA and TSFP+ technology. Oclaro has enabled 85 degrees C operation by optimising the operation temperature of the ILMZ chip and -40 degrees C operation by developing TEC to lower power consumption, as well as improving power dissipation of key components.

Oclaro expects to begin sampling the 10 Gbit/s TSFP+ I-temp in April, with volume production due to start in the third quarter of 2017.

400 Gbit/s CFP8 transceiver

Oclaro's 400 Gbit/s CFP8 transceiver targets core routers/transport applications and leverages its EML laser and receiver technology to deliver higher data rates between high-end routers and optical transport systems. At OFC Oclaro will demonstrate the CFP8 operating with 8 lasers at 50 Gbit/s PAM4.

With a 40 x 102 x 9.5 mm form factor, the 400 Gbit/s CFP8 transceiver provides a high density, high-throughput solution. The CFP8 leverages technology from Oclaro's earlier CFP, CFP2 and CFP4 designs, including its cooled 1310 nm 28 Gbit/s EA-DFB lasers, integrated TOSA and ROSA and 28 Gbit/s 4 channel integrated PIN-PD array.

The CFP8 transceiver for reach of 2 km and 10 km is compliant with 400GBASE-LR8 optical and 400GAUI-16 electrical interface specifications, offers EML laser technology offering good margin over IEEE 400 Gigabit Ethernet optical specifications and receiver bandwidth capability to allow interfacing with different lasers.

Oclaro's CFP8 product is currently sampling, with volume production scheduled for the second half of 2017.

The demonstration is designed to show that 53 Gbaud PAM4 PHYs can enable a production-grade EML laser to replace four 25 Gbit/s NRZ lasers; thereby improving the scalability of 100 Gbit/s transceivers, as well as providing the basis for duplex single mode fibre for 400 Gbit/s small form factor modules.

The demonstration comprises MACOM's 16 nm, 56 Gbaud PAM4 PHY IC on an evaluation board driving an optical loop back through a Source Photonics TOSA and ROSA. The small form factor TOSA package developed by Source Photonics uses its internal 53 Gbaud EML laser, which can deliver a more than 3 dB improvement over the proposed 100GBASE-DR OMA specification.

The joint 53 Gbaud PAM4 demonstration utilising a compact TOSA and ROSA combination, is designed to operate below the KP4 FEC requirement with a 6dB loss budget. Source Photonics and MACOM believe that the demonstration marks a key step toward realising a commercial single lambda solution able to replace many four channel solutions.

Source Photonics also announced that in cooperation with Semtech it is demonstrating a 53 GBaud PAM4 compact ROSA capable of supporting a single lambda 100 Gbit/s QSFP28. The demonstration comprises an optical loop back from a Source Photonics' 53 GBaud TOSA using a production-grade EML laser and 53 GBaud ROSA based on Semtech's GN1089 TIA. The combined TOSA and ROSA link can support a loss budget of 5 dB and better than 1 x 10-5 BER over the link.

InnoLight Demos 400G OSFP

InnoLight Technology based in Suzhou, China, a supplier of next generation cloud computing optical transceivers, has announced volume shipments of a suite of QSFP28 products and the availability of what it claims is the first 400 Gbit/s OSFP at OFC 2017 in Los Angeles.

InnoLight noted that 100 Gbit/s QSFP28 has become the de-facto standard for optical interconnects for cloud networks, as on a cost-per-gigabit basis 100 Gbit/s QSFP28 can be significantly more cost effective compared with 10 Gbit/s SFP+ and 40 Gbit/s QSFP+. As a result, the industry is rapidly deploying QSFP28 connections.

To support this transition, InnoLight is introducing a complete portfolio of QSFP28 optics solutions, as follows: SR4; eCWDM4; eSR4; CLR4; AOC; LR4 (Ethernet); QSFP28 to 4 x 25 Gbit/s SFP28 AOC; LR4 (dual rates); PSM4; LR4 (receive only); CWDM4; and ER4-Lite.

InnoLight stated that it is currently offering seventeen QSFP28 parts in mass production. The company noted that it is developing 400 Gbit/s solutions based on both the OSFP and QSFP-DD form factors to enable the optimal price-performance.

In addition, to support the 400 Gbit/s expansion, InnoLight will conduct a live demonstration of 400 Gbit/s OSFP optics during OFC.

PacketLight's CPP features five tiers and includes: training, both technical and sales, designed to help partners understand customers' requirements for WDM solutions; and custom design blueprints, with the sales support team providing network designs, assisting with technical presentations and demonstrations for customers. It also provides partners with technical support, 24 x 7.

PacketLight's products are designed to provide optical transport for high speed, secure data centre interconnect (DCI) and metro networks. Its technology is designed to increase spectral efficiency, optimise wavelength resources and enable higher fibre and metro network utilisation.

In February, PacketLight announced a partnership with Avelacom to build a high speed network from London to Moscow using its optical transport solutions. The PacketLight solution was designed to reduce network latency and enable the company to meet the demands of capital markets for low latency data transport across the continent.

Avelacom specifically selected PacketLight's PL-1000GT muxponder/transponder solution, and PL-1000IL platform, to establish a 100 Gbit/s low latency DWDM long-haul network spanning 1,100 km, with full add/drop capability at all major sites.

In November 2016, PacketLight launched the PL-2000M transport solutions for DCI and metro networks. The new muxponder/transponder is claimed to enable 30% lower cost and 2x increase in the spectral efficiency for improved network utilisation. The product supports carrier-grade coherent 200 Gbit/s tunable uplink, capable of serving applications and protocols including data, storage, OTN and TDM.

Infinera's Instant Network Delivers Software Defined Capacity for Optical Transport

Infinera introduced Instant Network capabilities for delivering software defined capacity (SDC) for cloud scale networks.

The new capabilities extend Infinera Instant Bandwidth, which provides software activation of service-ready optical capacity in a few hours on networks powered by its DTN-X platform and equipped with its unique photonic integrated circuits (PICs). Infinera introduced Instant Bandwidth in 2012 and more than 70 Service Providers are now using it. In 2015, Infinera introduced Time-based Instant Bandwidth in 2015, enabling software activation of bandwidth licenses for a limited duration.

Instant Network adds Bandwidth License Pools, Moveable Licenses and Automated Capacity Engineering (ACE). It also extends SDC to new Infinera platforms, which support flexible grid and sliceable 2.4 terabit super-channels powered by the Infinera Infinite Capacity Engine.

Highlights:

  • Bandwidth License Pools: The new Bandwidth License Pool functionality enables service providers to activate capacity at the same time as an invoice is issued for that capacity, reducing capital expenditures for idle capacity. This new capability enables capacity to be deployed in minutes, while previously, service providers would purchase a license before the capacity was software-activated, which resulted in deployment taking a few hours.
  • Moveable Licenses: New Movable Licenses enable service providers to use software to move bandwidth licenses across the network as traffic conditions change or fiber cuts occur. Previously, licenses were fixed to a specific line module or platform. Moveable licenses reduce capital expenses by reducing idle capacity provisioned specifically for network resiliency and increase agility when responding to customer demands for new services.
  • Automated Capacity Engineering (ACE): The new ACE application takes previously manual offline route and capacity planning processes and implements those algorithms in a microservices-based path computation element (PCE). ACE understands optical impairments and computes optimal Layer 0 routes between nodes across multiple paths, including automatic routing and wavelength assignment with multiple path constraints such as traffic engineering cost, distance and latency.

Infinera Instant Network capabilities are planned across the Infinera DNA software and the Xceed Software Suite. Instant Network Bandwidth License Pool and Moveable Licenses are available now. ACE is planned for 2018.

Infinera said its Instant Network  enables service providers to automate optical capacity engineering and scale optical capacity in minutes by using Infinera’s Xceed and Digital Node Administrator (DNA) software.  It also sets a foundation for cognitive networking, which includes advanced analytics, machine learning from streams of network telemetry data, autonomous operation of routine tasks, predictive analysis of network problems before they occur and proactive recommendations for network optimization to further reduce operational expense and improve service reliability.

“Infinera is committed to providing our customers with innovative solutions to help them win in the markets they serve,” said Dr. Dave Welch, Infinera co-founder and president. “Software defined capacity is a requirement to realize the benefits envisioned by SDN and network functions virtualization. Infinera Instant Network extends our success with Instant Bandwidth, leading the market for software defined capacity while lighting the way to cognitive networking.”

Fujitsu Enhances and Expands 1FINITY Family for DCI

Fujitsu Network Communications announced enhancements to its 1FINITY T100, including a hyper-dense transponder packaged together with the new 1FINITY T400, a 1 Tbps layer 1 aggregator. By

The company said that by decoupling the transponder and the aggregator, both of which are based on open software and open optics, it can offer customers greater architectural flexibility and industry-leading 10GbE to 100G aggregation density for data center interconnect applications. When the T400 and T100 are deployed together, the unique design of the “decoupled” aggregator and transponder provides ten times better 10GbE to 100G aggregation density than existing solutions.

Some highlights:

  • The 1FINITY T100 Transport blade, which is designed for 100G and 200G coherent optical transport between data centers in point-to-point or ring topologies, can be deployed independently, in conjunction with other 1FINITY blades such as the L100 Lambda series to provide ROADM capability, or over a third-party FOADM. Numerous feature enhancements have been added to the T100 platform. Zero touch provisioning automates configuration and provisioning, significantly speeding installation and reducing operating expenditures. Streaming telemetry technology provides an improved view of network performance without taxing software management resources to such an extent that other management functions are adversely impacted. Ethernet Link Layer Discovery Protocol (LLDP) snooping helps identify network topology with automated network discovery, enabling better planning and monitoring. And for enhanced optical security, the T100 has line-side OTN layer 1 encryption using Advance Encryption Standard (AES-256) for each 100Gb client.
  • The new 1FINITY T400 Transport blade provides a hyper-dense architecture that is purpose-built for layer 1, 10GbE to 100G aggregation. The platform’s open optics are comprised of 10 x QSFP28 100G-BaseR service ports and 25 x QSFP+ 40 GbE client ports. A 4:1 optical fan-out cable is used to deliver up to 100 x 10GbE client ports. Like the T100, the T400 has zero touch provisioning and AC or DC power supplies. The T400 reduces energy costs with a low power consumption of 0.45W per GbE.

“Our data center interconnect solutions are designed to meet the needs of the country’s largest service providers and data center operators,” said Chris Podraza, head of the optical business unit, Fujitsu Network Communications, Inc. “1FINITY solutions offer unmatched openness, flexibility, density and security. Implementing 1FINITY products, like the latest generation of the T100 and the T400, allow customers to grow their business and to be well-positioned to meet future network needs.”
