Cignal AI forecasts 400G Coherent WDM shipments in 2020

Shipments of 400G coherent WDM volume starts to ramp this year, led by Ciena deployments and then followed by other suppliers six to nine months later, according to a newly-published, bi-annual Optical Applications Report report from Cignal AI, an independent research firm based in Boston. The introduction of small form factor 100G and 400G pluggable models will be a major catalyst.

“Cignal AI has close relationships with equipment and component manufacturers, as well as end users, and these relationships give us a unique insight into the optical equipment market.  From this vantage point, we can forecast emerging technologies such as coherent 400G WDM usage,” states Andrew Schmitt, lead analyst for Cignal AI. “Pluggable 400G ZR modules should enter the market by 2019, and they will be the final nail in the coffin for 10G WDM networks.”

Some key findings:

  • Both 100G and 400G coherent will be widely adopted at the edge of the network by the end of 2021.
  • Cisco is growing 100G port deployments faster than all other vendors in the market.
  • Equipment originally designed for DCI applications is rapidly evolving into applications outside the datacenter. Cignal AI is now using "Compact Modular for this class of products.
  • Spending on compact modular equipment more than tripled in the first half of 2017, compared to the same period last year. Ciena, Cisco, and Infinera are the market share and technology leaders for this sector.
  • Revenue for packet-OTN systems grew in the double digits in the first half of 2017, compared to the same period last year.

CWDM8 MSA targets 400G data centre links at 2 km and 10 km

Leading vendors, including Accton, Barefoot Networks, Credo Semiconductor, Hisense, Innovium, Intel, MACOM, Mellanox, Neophotonics, and Rockley Photonics, have formed a new CWDM8 MSA (8-wavelength Coarse Wavelength Division Multiplexing Multi-Source Agreement) Group dedicated to defining optical specifications and promoting adoption of interoperable 2 km and 10 km 400 Gb/s interfaces over duplex single-mode fiber.

The goal is to develop optical link specifications that will enable cost-effective, low power consumption 400G duplex single-mode optics using 50G per wavelength optical NRZ modulation, all while maintaining full compatibility with standard 50G PAM4 electrical interfaces.

The group is targetting next-generation module form factors such as QSFP-DD, OSFP, and COBO, to handle the 400 Gb/s interface at distances of 2 km and 10km for intra data centre of campus data centre connectivity.

"There is currently no adequate solution in the market to meet our needs for cost effective and uncooled 400G optical interfaces for 2km and 10km reaches. We welcome the formation of the CWDM8 MSA, which offers proven 50G NRZ technology to enable compact and low power dissipation form factors for 400G," stated Yu Li, VP of Data Center Switching, Huawei.

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.

EXFO's optical spectrum analyzer tests up to 400G

EXFO released its new FTBx-5255 Optical Spectrum Analyzer (OSA) designed for the field testing needs of telecom service providers, internet content providers and network equipment manufacturers.

A key capability of the new OSA is that it supports in-service network testing of the optical signal-to-noise ratio (OSNR) of 100G/200G/400G (Pol-Mux) signals, which means that service providers and ICPs do not have to interrupt their operations to perform these measurements.

EXFO's new OSA also enables in-service network testing of O-band pluggables and L-band transceivers, as well as CWDM spectral analysis.

"Customers have repeatedly expressed a need for a non-intrusive way of measuring OSNR on high-speed networks, to ensure they're meeting customer expectations for quality of service," said Stéphane Chabot, EXFO's Vice President, Test and Measurement. "Our new portable optical spectrum analyzer equips service providers, internet content providers, and NEMs for testing live networks, saving them time and significantly reducing operating expenses while making troubleshooting faster and better. No one else can offer them the ability to address all OSA testing applications with a single module."

The FTBx-5255 is available in EXFO's FTB-2, FTB-2 Pro and FTB-4 Pro portable test platforms as well as in the LTB-8 platform for rackmount and lab applications.

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.

New QSFP-DD MSA Targets 400G

The Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi Source Agreement (MSA) group has released a specification for the new QSFP-DD form factor, 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 Gbps and 100 Gbps network applications.

Specifically, the new QSFP-DD form factor expands the standard QSFP four-lane interface by adding a row of contacts providing for an eight-lane electrical interface, each operating up to 25 Gbps with Non-Return-to-Zero (NRZ) modulation or 50 Gbps with Pulse Amplitude Modulation (PAM4). This adaptation allows the QSFP-DD form factor to address solutions up to 400 Gbps aggregate per QSFP-DD port, while providing backward compatibility to 40 Gbps and 100 Gbps. A single switch slot can support up to 36 QSFP-DD modules providing up to 14.4 Tbps aggregate capacity. With an advanced thermal design, the new QSFP-DD solution can support modules up to 12W, providing significant system design flexibility.

Huawei Intros 4 Tbit/s Line card for NE9000 Backbone Router enabling 80 Tbit/s Capacity

Huawei has unveiled what it claims is the first 4 Tbit/s router line card that enables high density 100 Gigabit Ethernet interface interconnection and equips its NE9000 backbone router to support a total capacity of up to 80 Tbit/s.

The NE9000 platform comprises part of Huawei's CloudBackbone solution, which is designed to provide higher capacity and improved efficiency for core node and data centre interconnection (DCI) applications in cloud environments.

The new Huawei 4 Tbit/s router line cards utilise the latest Solar5.0 network processing chip design and is claimed to deliver the highest density 100 Gigabit Ethernet interface interconnectivity and to help operators to build flattened backbone networks. In addition, as the NE9000 platform provides support for 400 Gigabit Ethernet interfaces, end-to-end 400 Gbit/s links can be implemented with transport devices for a simplified network topology.

The NE9000 router provides capacity of up to 80 Tbit/s, enabling support for up to 2 million concurrent online users streaming 4K video and designed to address current and future network bandwidth requirements. The NE9000 also features energy-saving capabilities, with a single device claimed to consume 0.4 W/Gbit/s.

As a core element of Huawei's CloudBackbone solution, the NE9000 is designed to work with the company's Network Cloud Engine to offer centralised control and allow real-time detection of traffic changes on the network, thereby helping operators to implement flexible adjustment of the network and improve network efficiency.

Additionally, the Huawei NE9000 can be separated into multiple virtual devices to enable unified bearing of multiple services and the use of fewer network nodes. Moreover, service isolation can be provided utilising virtualisation technology for enhanced network security and reliability.

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 Demos 400GbE via Four-Level PAM4

Ixia successfully demonstrated 400 Gigabit Ethernet (GbE) technology by combining eight electrical lanes of 56 Gbps, defined as 400GAUI-8 by IEEE802.3bs, via four-level Pulse Amplitude Modulation (PAM4).

Ixia said currently supports and collaborates with two key multisource agreement (MSA) development groups to help drive the effectiveness and efficiency of 400 GbE technology: double-density quad small-form-factor pluggable (QSFP-DD) MSA, and Octal Small Form Factor Pluggable (OSFP) MSA.

The QSFP-DD MSA Group is addressing the technical challenges of achieving a double-density interface and ensuring mechanical, electrical, thermal, and signal-integrity interoperability for module components produced by different manufacturers. Collaboration through the MSA is intended to enable faster implementation and easier operation of the high-speed, double-density quad small-form-factor pluggable interface in networking equipment. QSFP-DD addresses increasing global bandwidth consumption with its ability to quadruple aggregate switch bandwidth while maintaining port density.

The OSFP MSA is comprised of 49 industry leaders who are tasked with defining the form factor for new 400 GbE transceiver module that will support the full range of 400 GbE optics technologies, from datacenter to metro reach.
