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.

Crehan: Branded Data Center Ethernet Switch Revenue Tops $10B in '16

Branded data center Ethernet switch sales exceeded $10 billion in 2016, according to the latest report from Crehan Research Inc.  The report notes that this revenue level, a record, was accompanied by the strongest market growth rate since 2013.

“2016 was a strong year for data center Ethernet switching, with robust customer spending on public, private and hybrid clouds," said Seamus Crehan, president of Crehan Research. “40GbE and 100GbE switches were the main market drivers, with a total of over one billion dollars in revenue growth. However, 40GbE data center switch spending softened in the second half of the year, while spending on 100GbE continued to increase throughout the year."

In addition to the strong top-level revenue performance, notable results from Crehan’s data center switch report include:

  • 25GbE shipments ramped exponentially during 2016, exceeding a one-and-a-half million annual port run-rate by 4Q16, driven mostly by Cisco’s Cloud Scale Nexus 9000 series 
  •  100GbE shipments increased dramatically throughout the year, also surpassing a one-and-a-half million annual port run-rate by 4Q16, with data center switches from Arista and Cisco accounting for most of the year’s volume 
  • 10GBASE-T data center switch shipments increased more than 60% for the full year 2016  Cisco accounted for over half of total branded data center Ethernet switch revenues in 2016 
  • Arista, Huawei and Juniper all saw data center switch revenue increases in excess of 30% in 2016, resulting in share gains  
  • The top-line 2016 average selling price per data center switch port was almost identical to that of 2015  

“The total market average selling price remained remarkably stable in 2016, despite factors such as intense data center switch competition and the price negotiating power of the large hyper-scale cloud customers," Crehan said. "Migration to higher speeds and strong adoption of modular switching were key factors in the stability.”

Huawei Proposes X-Ethernet for 5G Fronthaul/Backhaul

Huawei is proposing a new X-Ethernet variation to bring TDM-like deterministic characteristics to 5G fronthaul/backhaul deployments.

The Network 5.0 Team at Huawei’s Network Technology Laboratory, part of the company’s “Laboratory 2012” developed the innovative X-Ethernet technology.

Huawei said X-Ethernet fundamentally solves the problem brought by the high bandwidth, determinacy, low-latency, hard isolation and low-cost requirements of 5G. X-Ethernet holds many innovative features such as a Layer 1.5 Switch, Hybrid Multiplexing and Ethernet E2E Flexible Hard Pipe. The Layer 1.5 Switch is based on the native Ethernet kernel.  Since it can avoid L2/L3 packets storage-and-forwarding, deterministic low-latency can be guaranteed. The Hybrid Multiplex technology is realized by enhancing Ethernet code block function.

Huawei has released X-Ethernet technology for 5G bearer networks at the ITU-T 2020 FG Workshop and Demo Day Wireline Technology Enablers for 5G conference in Geneva, Switzerland.

UNH-IOL Launches Three Time Sensitive Networking Consortiums

The University of New Hampshire InterOperability Laboratory (UNH-IOL) has launched three industry-specific time sensitive networking (TSN) consortiums – Automotive Networking, Industrial Networking, and ProAV Networking - designed to provide deterministic performance within standard Ethernet for real-time, mission critical applications.

UNH-IOL will provide high quality test plans, tools, and test beds for the consortiums.

TSN standards enable deterministic real-time communication over Ethernet, allowing solutions to be built to provide extremely precise, predictable timing across the network. By adding features to Ethernet such as time synchronization, ingress policing, seamless redundancy, frame preemption, scheduled traffic, and stream reservation, TSN ensures mission-critical, time sensitive data is not held up on the network, promoting an interoperable ecosystem spanning across many industries.

“Standards-based precise time, guaranteed bandwidth, and guaranteed worst-case latency in a converged Ethernet network is a game-changer to many industries,” said Bob Noseworthy, Chief Engineer, UNH-IOL. “Through UNH-IOL’s industry-specific TSN consortiums, companies can be at the forefront and drive the technology forward by validating their solutions with a full suite of testing services, which will allow applications such as self-driving cars and the Industrial Internet of Things (IIoT) to take off.”

AT&T to Launch 400GbE Business Service

AT&T is planning to launch 400 Gigabit Ethernet business services.  A trial is planned for early 2017 across the company's production network.

The 400 Gigabit Ethernet testing will be performed in 3 phases:

  • Phase 1: Will use 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.
  • Phase 2: Will trial a 400GbE on a single 400G wavelength across AT&T’s OpenROADM metro network. We’ll use optical gear from Ciena, a developer of next-generation coherent optical solutions, to show the network is ready to transport 400GbE to serve our customers in a metro area.
  • Phase 3: Will test the first instance of a 400GbE open router platform. The “disaggregated router” platform uses merchant silicon and open source software – another industry first.

“Although there have been efforts focused on 400 Gigabit Ethernet viability and industry standards over the past couple of years, we are excited to be the first to implement a pilot,” said Rick Hubbard, senior vice president, AT&T Network Product Management. “400GbE has the potential to transform how our largest retail and wholesale customers manage their networks today.”

AT&T noted that data traffic on the its network grew more than 150,000% between 2007 and 2015.

Crehan: Spending Spikes for Branded Data Center Ethernet Switches

In the first half of 2016, spending on branded data center Ethernet switches saw the strongest growth since the first half of 2012, according to the most recent report from Crehan Research Inc.

The market’s growth rate in the first half of 2016 approximately doubled the rate seen in the previous two years leading to record results, according to the report.

“Customer spending and deployments of branded data center Ethernet switches accelerated significantly during the first half of this year due to a number of factors," said Seamus Crehan, president of Crehan Research.

“First, we have seen the recent introduction of numerous products with compelling features and value propositions including programmability, automation, and telemetry, which help to enable software-defined data center networks. Second, we are seeing the price per gigabit of bandwidth drop significantly, enticing customers to upgrade their existing infrastructure. And lastly, we are seeing a lot of early excitement and interest around 100 gigabit Ethernet switching, where data center shipments have gone from about ten thousand ports in the first half of 2015 to well over one-hundred thousand ports in the first half of 2016."

Some highlights:


  • Over half of all spending on branded data center Ethernet switches during the first half of 2016 was on Cisco products, with particularly strong adoption of the company’s Nexus 3000 and 9000 lines. 
  • The strongest vendor revenue growth during the same time period was seen by Arista and Huawei, each of which increased revenues by over thirty percent in comparison to the first half of 2015. 
  • Juniper Networks’ revenue also had a very healthy increase – in the twenty-percent range – as its QFX portfolio of data center Ethernet switches saw strong acceptance within the telco, cable and cloud service provider markets.
