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.

NeoPhotonics Demos Coherent Transceiver for 400/600Gbps

At this week's Optical Fiber Communications (OFC) Conference and Exhibition in Los Angeles NeoPhotonics will demonstrate its pluggable Coherent CFP2-ACO module for 400G and up on a single wavelength over metro distances.

The NeoPhotonics' ClearLight CFP2-ACO Platform is capable of achieving single wavelength 200G, 400G and 600 Gbps transmission over Data center Interconnect through metro/regional distances.

The company said its ClearLight CFP2-ACO platform uses next generation optical components which are based on platforms that have been proven in volume production for 100G and 200G network applications. The platform uses NeoPhotonics’ high bandwidth Class 40 Coherent Receiver capable of 64Gbaud with 16-QAM to 64-QAM modulation.  This high bandwidth receiver maintains high sensitivity to simplify migration from 100G to 200G and 400G links.  The platform also uses NeoPhotonics’ industry leading high power, external cavity, ultra-narrow line width tunable laser with low power consumption. The ultra-narrow line widths enables higher order constellations with less processing requirements from the DSP.

The ClearLightTM  64 Gbaud CFP2-ACO demonstrates the ability to scale data capacity to 400G/600G on a single wavelength while maintaining performance and link budgets in DCI or metro/regional links.  The data capacity scaling optimizes the cost per bit and thus enables broad deployment of coherent transmission from short to long reaches.

"Our new ClearLightTM 64 Gbaud CFP2-ACO 400G/600G pluggable coherent transponder demonstrates a powerful new platform for NeoPhotonics which is capable of efficiently implementing 400G to 600G transmission networks," said Tim Jenks, Chairman and CEO of NeoPhotonics. "This exciting new platform is made possible by our Advanced Hybrid Photonic Integration technology utilizing our latest advances in high bandwidth receivers and ultra-narrow linewidth lasers in conjunction with higher order modulation, " continued Mr. Jenks.

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.

Ixia and Viavi Debut 400GbE Test System with Forward Error Correction

Ixia is working with Viavi Solutions to showcase the world’s first public interoperability demonstration of a test system running bi-directional 400GbE line rate traffic with RS-544 Forward Error Correction (FEC), as currently defined in the IEEE 802.3bs draft standard.

The demo, which will be shown at next week's ECOC 2016 conference in Düsseldorf, Germany, will show full interoperability of independently developed MAC, PCS, and RS-544 FEC IP by each company, including the critical FEC element that enables 400GbE error-free data packets to be carried over fiber links, on readily available hardware components.

The companies said this demonstration is intended to show that it is now possible to successfully bring products to market that interoperate in accordance with emerging 400GbE standards and are ready for adoption by network equipment manufacturers as well as companies that need to move forward with their 400GbE implementation.

Ixia’s full portfolio of network infrastructure test systems, including the 400GbE test system, offer the same send/receive capabilities on all speed ports, with packet lengths as small as 49B, which is smaller than the minimum Ethernet frame size. It is also capable of sending and receiving a single 400GbE line rate flow at any packet size.

Viavi’s Optical Network Tester (ONT) has been proven in lab testing of 100G components, and now has the industry’s first 400G support to include FEC and PAM4 modulation. Pioneers of the high-speed network ecosystem now have a comprehensive, integrated platform for design, development, and validation of 400G technologies including CFP8 pluggable 400G optics.

“It is a very exciting time in high speed networking technology, and we are delighted to work together with Ixia to demonstrate the first stages of a vibrant and healthy 400GbE ecosystem,” said Paul Brooks, 400G technology lead, Viavi Solutions. “We are all committed to helping our customers successfully bring 400GbE products to market with the confidence that they can interoperate and perform to expectations.”

Inphi Intros 400GbE PAM4 for Next-Gen CFP8 Modules

Inphi announced a 400GbE platform solution for next-generation 400G CFP8 modules.

The solution uses Inphi's highly integrated, lowest power 4-level Pulse Amplitude Modulation (PAM4) digital signal processing (DSP) IC, which supports IEEE P802.3bs 400G/s Ethernet standard alongside its linear TIAs and linear drivers for client based cloud interconnects.

Inphi said its the foundation of its 400G PAM4 PHY IC is a highly configurable and DSP Engine that can be targeted to multiple different performance oriented applications for optical based interconnects, while keeping an extremely low power profile.

The solution multiple channels along with transmit and receive PAM4 and forward error correction (FEC) functions on a single package.

OIF Launches 100G Serial Electrical Links

The Optical Internetworking Forum (OIF) has begun work on a 100G Serial Electrical Link project.

The very short reach (VSR) CEI-112G chip-to-module interface project will support a nominal lane rate of 112 Gb/s, enabling narrower interfaces to optical modules and is expected to be more energy efficient than previous interfaces. The CEI-112G-VSR specification doubles data rates over the current generation CEI-56G-VSR interfaces.

The OIF said this work will be followed by both shorter and longer reach projects.

“As bandwidth increases, electrical interfaces need to reflect that trend. Given the lead times, development of standards for the next generation of electrical links needs to start now,” said David Stauffer of Kandou Bus and the OIF’s Physical and Link Layer Working Group Chair and board member. “The OIF is continuing its roadmap for 100 Gb/s thru 400 Gb/s and beyond applications, addressing multiple reaches for chip-to-chip and chip-to module interfaces.”

Ixia Demos 400GbE Test with Forward Error Correction

Ixia will conduct the first public demonstration of its test system running 400GbE with RS-544 Forward Error Correction (FEC) at this week's Interop Tokyo 2016.

RS-544 FEC is a digital signal processing technique used to enhance data reliability. It does this by introducing error correcting code that is calculated prior to data transmission. The IEEE P802.3bs Task Force defines two FEC engines that are required for the electrical interface that supports 400GbE.
