Ixia delivers 200/100/50GE test for its 400GE QSFP-DD system

Ixia, a division of Keysight Technologies, announced first shipment of a 400GE test system with multi-rate 200/100/50GE speed options for the K400 400GE QSFP-DD load module family.

These multi-rate speed options allow network equipment manufacturers to test products at speeds based on the new IEEE 802.3cd draft standard and IEEE 802.3bs standard using the 400GE QSFP-DD module at 200GE, 100GE, and 50GE speeds, from a single port.

Ixia said 56 Gbps technology is at the forefront of Ethernet speed evolution—moving from legacy 25GE, 50GE, and 100GE (based on 28Gbs technology) to the new 200GE, 100GE, and 50GE interfaces expected to come to market this year. The Ixia K400 QSFP-DD load module is the only shipping test solution that can validate these technologies using 400GE-port fan-out media for testing 400GE, 200GE, 100GE, or 50GE multi-speed or single-speed network devices.

“Flexible test solutions are necessary to develop higher speed, multi-rate, high-density Ethernet products for the leaders in the data center space,” said Sunil Kalidindi, vice president product management, at Keysight’s Ixia Solutions Group. “Network devices such as routers, switches and servers must be able to operate at all new speeds in the IEEE 802.3cd draft specification and IEEE 802.3bs on most, or all, ports on their devices.”

NTT Electronics announces 64GBaud coherent DSP

NTT Electronics (NEL) has begun sampling a 64GBaud high-performance coherent DSP for DWDM optical transport systems. The DSP core leverages Broadcom’s 16nm CMOS fin-FET high-speed mixed-signal technologies which enhances per-lambda capacity by two-to-three times up to 600Gbps/λ.

NEL's new DSP supports flexible line capacities by combining multiple Baud-rates and modulation-formats, from 100Gbps/λ by 32GBaud QPSK to industry-first 600Gbps/λ by 64GBaud 64QAM.

The company says it is able to achieve a range of per-fiber DWDM capacity, from 5Tbps for tens of thousands of kilometers Ultra Long Haul (ULH) to over 30Tbps for 120km ZR transmission reaches, and further doubling the capacity by using both C-band and L-band. Real-time coherent processing at 64GBaud enables thousands-of-kilometers LH transport at 200Gbps/λ by Dual-Polarization (DP) QPSK, hundreds-of-kilometers Metro transport at 400Gbps/λ by DP 16QAM, or 120km ZR transport at 600Gbps/λ by DP 64QAM.

“Every Service Provider needs to maximize fiber capacity to meet increasing bandwidth demand,” said Haruhiko Ichino, NEL Executive Vice President and General Manager of Broadband System & Device Business Group. “We are strongly committed to be a pioneer in the coherent DSP innovation and to provide merchant-silicon solutions for cost-effective upgrades in LH, Metro, and shorter-reach data-center-interconnect (DCI) applications.”

Commercial production is expected in the second half of 2018.

Telstra tests 400G in Melbourne with Ciena, Ericsson

Telstra, Ericsson, and Ciena demonstrated 400 Gbps speeds over 61.5 GHz spectrum on Telstra’s transmission network in Melbourne, attaining what the companies termed "the highest spectral efficiency per fibre pair ever achieved in a live environment." This implies that a maximum 30.4 terabit per second (Tbps) bandwidth is possible on Telstra’s transmission network in Melbourne. The highest previous mark was 25.6 Tbps.

Ciena said that result was made possible through the deployment of software programmable 400Gbps wavelengths using Ciena’s WaveLogic Ai modem technology on the 6500 Packet-Optical Platform, in combination with Ciena’s Blue Planet Manage Control Plan (MCP) and Liquid Spectrum applications. Ericsson provides end-to-end systems integration.

Telstra has deployed Ciena's programmable coherent modem technology, which offers up to three times data capacity and enables up to 60 percent reduction in power per bit compared to the modem technology currently deployed in the Telstra network.

David Robertson, Director of IP and Transport Engineering at Telstra, says: “Over the next five years we forecast traffic on our network will grow by five times. We are investing in our network and developing these innovations to meet this growing demand by providing unprecedented levels of scale, automation and intelligence. This technology will be deployed in our domestic transmission network and we will look for opportunities to use it in Telstra’s international subsea cable network, which is the largest in the Asia-Pacific region.”

Emilio Romeo, Head of Ericsson Australia and New Zealand, says: “We are proud to be supporting our long-term partner Telstra with end-to-end systems integration expertise to deliver innovative solutions that will ultimately improve overall efficiency of the network. Deployment of these technologies will help Telstra to prepare for the ever-increasing demand for data. This will give Telstra the ability to predict and address connectivity and capacity challenges as they emerge, enabling them to respond and allocate capacity across paths in real time.”

Steve Alexander, Ciena’s Chief Technology Officer says, “As high-bandwidth applications become further ingrained in our daily lives, the implementation of a more intelligent and adaptive network – one that lets operators eliminate complexity by combining intelligent automation, real-time performance monitoring, and the ability to continuously tune their network – is critical. These accomplishments will prepare Telstra’s network to better respond to customer demands.”

AT&T Tests Single Wavelength 400G Ethernet

AT&T completed testing a single-wavelength 400 gigabit Ethernet (GbE) circuit across its production network.

The multi-step trial used open-sourced white boxes to act as network equipment. AT&T said this aligns with its move toward an open, software-centric network.

“Introducing 400 GbE is a natural next step. Customer demands have shifted to faster speeds, more video-centric content and cloud integration,” said Roman Pacewicz, chief product officer, AT&T Business.

“This industry-first also aligns with our shift toward an open and software-centric network. Utilizing open-source controller technology, the end-to-end service transported across the AT&T OpenROADM metro network – using optical gear from Ciena, a developer of next-generation coherent optical solutions – provides further flexibility and cost-effective services for customers. Prior to this successful trial, all other field demonstrations have required multiple wavelengths to create a 400 GbE connection."

http://www.att.com

In October 2016, AT&T announced plans to conduct 400 Gigabit Ethernet testing 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.

Dell'Oro Forecasts 400 Gbit/s switch market

In the latest Ethernet Switch - Data Center 5-year Forecast Report from Dell’Oro Group, the research firm forecasts that the market for 400 Gbit/s switches will ramp strongly starting in 2019, while from 2020, 25 and 100 Gbit/s will account for more than half of the data centre switch port shipments.

Dell'Oro reports that the second half of 2016 saw the beginning of a major speed upgrade cycle in the data centre based on 25 Gigabit Ethernet SerDes technology, with shipments of 25 and 100 Gbit/s reaching hundreds of thousands of ports per quarter despite supply constraints on 100 Gigabit Ethernet optical transceivers. Adoption of 25/100 Gbit/s is predicted to accelerate in 2017 and to comprise over half of data centre switching ports within only 4 years of initial shipments.
Dell'Oro notes that the rapid growth will be driven by a low price premium over preceding 10 and 40 Gbit/s port speeds as well as switch vendors consolidating their products to provide fewer speed options.

In its separate Ethernet Switch - Layer 2+3 5-year Forecast Report, Dell'Oro forecasts that the overall Ethernet switch market will grow to exceed $28 billion in 2021, driven by factors including speed upgrades, software-defined networking and subscription-based models.


Dell'Oro expects that the Ethernet switch market will remain robust over the next 5 years, with revenue and shipment growth driven primarily by the data centre segment, while the campus switching market is forecast to continue to be soft due partly to cannibalisation from WLAN.

ECI Cites Multiple Deployments of 400G Apollo Systems

ECI announced the continued deployment of its 400 Gbit/s solution to enable faster connectivity and meet growing bandwidth demand, with projects at key customers across Europe that have upgraded their networks using ECI's Apollo family of optical products with integrated 400 Gbit/s flex-grid blade.

ECI's Apollo platform is designed to enable service providers to meet current and future demand. The platform combines high-capacity, low-latency OTN transport and switching with software configurable, colourless, directionless and gridless optical routing, for enhanced efficiency. Equipped with the 400 Gbit/s blade, the solution allows for the flexible allocation of transmission rate and spectrum in accordance with service type, preference or distance.

In addition, the ability to configure a mix of rates on both client and line sides provides customers with improved efficiency and flexibility and reduced costs.

ECI cited companies that have recently implemented its 400 Gbit/s solution including:

  • The Dutch National Research and Education Network SURFnet, which established a 400 Gbit/s connection between Utrecht and Breda as part of an upgrade of its next generation network, SURFnet8. The link provides a direct connection, with high capacity to support the transfer of information between educational and research organisations at two major university cities.

  • German service provider NetCom BW, which already operates a major Apollo network, launched the 400 Gbit/s platform to provide a link between Stuttgart and Frankfurt, which will serve as the basis for a direct connection to Internet Exchange Frankfurt; the solution also allows for future growth via up to 88 parallel connections.

  • Romanian cable TV operator UPC, which has deployed the Apollo platform in its core ring that services the main cities in Romania such as Bucharest, Brasov, Cluj, Oradea and Timisoara. The Apollo 88 channel ring provides 400 Gbit/s connectivity with 100 Gbit/s service interface, replacing 10 Gbit/s interfaces.

  • German data centre operator New Telco, an ECI customer for nearly a decade, which deployed ECI's Apollo DWDM technology across the Frankfurt metro area to upgrade the existing 100 Gbit/s interfaces to 400 Gbit/s to provide higher port density and throughput.

NTT Com to Deploy 400G in Data Centers

NTT Communications will begin deploying a 400 Gbps optical transmission system in its data centers beginning this month.

The system will raise the transmission capacity of NTT Com's core network above 19Tbps per optical fiber, or more than double existing capacity.

The company said the 400G rate is achieved by using advanced digital-signal processing technology developed in house.

The main features and advantages of the 400G system are as follows:

  • Top-level energy and space savings
  • The new system reduces energy consumption per bps by 75% and space requirements by 80% compared to the existing system. The savings were achieved through a synergistic combination of advanced digital-signal processing technology and 16nm complementary metal-oxide semiconductor (CMOS) technology. Energy-saving integrated circuits can be constructed rapidly, enabling transmitters to be quickly deployed even in confined spaces at data centers.
  • More than double existing transmission capacity
  • The new system achieves more than double the transmission capacity per optical fiber compared to its predecessor system. To generate 400G signals, the system utilizes NTT's 16 quadrature amplitude modulation (QAM) for both phase and amplitude, and sub-carrier multiple transmission.
  • New OTN and 400GbE interfaces

In connection with the deployment, NTT Com will offer new optional network services for enterprises, including the sequential launch of OTN interfaces (OTU2, OTU2e and OTU4) mainly for wholesalers and data center users, and a 400GbE interface incorporating framing technology compatible with OTUCn which is the result from NTT's R&D.

To deliver new services and functions with even greater speed and flexibility, NTT Com will combine SDN technologies and dis-aggregation architecture, which can be redeployed as required according to function or module, replacing existing high-function, all-in-one dedicated equipment.

LightCounting Forecasts Optics Sales to top 4 ICPs

LightCounting, in its latest High-Speed Ethernet Optics report, finds that demand for Ethernet optics from leading Internet content providers (ICPs) continues to rise, with sales to the Top 4 ICPs - Amazon, Facebook, Google and Microsoft - forecast to increase from $0.5 billion in 2016 to $1 billion in 2017 and nearly $2 billion by 2022, representing around 30% of the global market for Ethernet transceivers.

LightCounting notes that supply shortages for 100 Gigabit Ethernet optics limited market growth in 2016, as vendors worked to ramp production. The research firm projects that, based on estimated manufacturing capacity for the leading suppliers of optics in 2017, demand will continue to exceed supply until 2018. Meanwhile, it expects volume shipments of 200 and 400 Gigabit Ethernet transceivers for applications in ICP mega-data centres will commence in 2019 and 2021, respectively.

Broken down by technology, LightCounting forecasts that the 40 Gigabit Ethernet segment will continue to decline having peaked in 2016, while sales of 100 Gigabit Ethernet solutions will continue to grow rapidly and peak at around $1 billion by 2019. For the 200/400 Gigabit Ethernet segment, it projects that sales will ramp from 2018 to reach around $200 million in 2019 and approach $1.2 billion by 2022.

LightCounting's forecast is based on a correlation between the growth rate of traffic inside mega-data centres and the bandwidth of optical transceivers sold into the market segment, while Amazon and Facebook recently stated that traffic in their facilities is increasing at a rate of around 100% per year.

Meanwhile, data on transceiver sales indicates that the top 4 ICPs increased bandwidth of optical connectivity by 70% in 2016, which is consistent with reported shortages in supplies of 100 Gigabit Ethernet optics. For 2017, LightCounting expects that bandwidth will increase by 90% as supply chain shortages moderate.

For the period 2018 to 22, LightCounting's projections assume that traffic growth in mega-data centres will decline gradually, while ICPs will find ways to use optical connectivity more efficiently. Even so, the research firm predicts that the global market for Ethernet optics will increase by 18% annually and exceed $6 billion by 2022.

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.

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.
