NTT Carriers One Petabit per Second over Single Fiber over 200 km

NTT has demonstrated a record inline optical amplified transmission of 1 petabit (1000 terabit) per second over a 205.6 km single strand of 32-core (light paths) optical fiber.

The experimental system used 32-core fiber with a new arrangement of cores to reduce inter-core light leakage, a fan-in/fan-out (FI/FO) device to couple light into the multi-core fiber, along with new digital coherent optical transmission technology. The result aws 31.3 Tbit/s capacity per core (680 Gbit/s per wavelength x 46 wavelength channels).  Multiplied by 32 cores, adn the total transmission capacity exceeded the petabit milestone.

The test was conducted in collaboration with the Technical University of Denmark, Fujikura Ltd., Hokkaido University, the University of Southampton and Coriant.

The transmission occurred within a single optical amplifier bandwidth (C-band), which is half the bandwidth used in a previous experiment the used C-band + L-band. NTT said its research indicates that it is potentially possible to carry 1 petabit per second over 1000 km, which is approximately the distance between major cities both in Japan and in Europe.

Ciena Launches Waveserver Ai for DCI

Ciena has introduced Waveserver Ai, designed to offer high capacity and power efficiency for data centre interconnect (DCI) applications together with the established server-like operational model delivered by the Waveserver portfolio.

The 'easy-to-automate' Waveserver packet-optical platform is designed to enable ultra-high capacity connections between data centre locations along with reduced network costs for enterprises and content providers. The new Waveserver Ai additionally enables the interconnection of multiple clouds for multi-tenant data centre and cloud providers to offer expanded support for high-speed, high-capacity services.

Ciena's Waveserver Ai solution allows increased capacity and service densities with minimal footprint in data centres where space may be limited. Leveraging the WaveLogic Ai coherent technology, the platform can scale to 2.4 Tbit/s in a single rack unit of space, representing a claimed 50–100% higher density compared to other compact DCI platforms. Additionally, with low power per bit performance, the solution can also help operators  reduce overall energy consumption.

Waveserver Ai can also help to simplify DCI planning and deployment leveraging a programmable coherent chipset that can be tuned from 100 up to 400 Gbit/s to optimise capacity over any distance, ranging from metro and regional to long-haul networks. As a result, with a single Waveserver Ai platform an operator can deliver single wavelength 400 Gbit/s capacity on short-haul links and 200 Gbit/s capacity for long-haul DCI applications.

Additionally, leveraging web-scale attributes the Waveserver Ai platform is designed to enable a simplified lifecycle, from planning and ordering to provisioning and maintenance, combined with a server-like deployment model. Via a suite of open APIs and management interfaces, the platform can be integrated into existing or new DCI networks and existing operational processes. Ciena noted that operators can also use its Emulation Cloud simulation environment to create, test and fine-tune customised applications.

Waveserver Ai is scheduled to be generally available in the second quarter of 2017.

Facebook to Contribute Open Packet DWDM to Telecom Infra Project

Facebook outlined its plan for Open Packet DWDM for metro and long-haul fiber optic transport networks.  The idea is to "enable a clean separation of software and hardware" based on open specifications.

Facebook had already developed a new "white box" transponder and routing platform called Voyager based on Open Packet DWDM, which it will contribute to the Telecom Infra Project.

Facebook said the Voyager open line system will include Yang software data models of each component in the system, and an open northbound software interface (NETCONF, Thrift, etc.) to the control plane software. This allows multiple applications to run on top of the open software layer, enabling software innovations in DWDM system control algorithms and network management systems.

The DWDM transponder hardware includes DSP ASICs and complex optoelectronic components, and thus accounts for much of the cost of the system. The hardware design leverages technologies implemented in Wedge 100, Facebook's top-of-rack switch, including the same Broadcom Tomahawk switching ASIC.  It also uses the DSP ASIC and optics module (AC400) from Acacia Communications for the DWDM line side with their open development environment.

Facebook worked with Lumentum to develop a terminal amplifier specification so that multiple applications can run on top of the open software layer to enable software innovations in DWDM system control algorithms and network management systems.

Some additional notes:

  • Equinix has successfully tested the Voyager solution and Lumentum’s open line system over 140km of production fiber. MTN also shared the results of their successful test of Voyager over their production fiber network in South Africa. Facebook, Acacia Communications, Broadcom, Celestica, Lumentum, and Snaproute are delivering a complete disaggregated hardware and software optical networking platform that is expected to significantly advance the industry.
  • ADVA Optical Networking is providing commercial support for Voyager, including all of the essential services and software support needed to make it a complete network solution that is ready for deployment.
  • Coriant is extending its networking software to enable engineering support for Voyager, providing routing and switching as well as DWDM transmission capabilities. The combination of DWDM and packet switching/routing opens up the potential for more open and more programmable network architectures.
  • The first TIP Ecosystem Acceleration Centers, sponsored by SK Telecom and Facebook, will open in Seoul in early 2017. Other TIP Ecosystem Acceleration Centers are being planned to encourage community participation. The latest companies to join TIP include Bell Canada, du (EITC), NBN, Orange, Telia, Telstra, Accenture, Amdocs, Canonical, Hewlett Packard Enterprise, and Toyota InfoTechnology Center.

Infinera Validates Optical Line Systems with Lumentum's White Box

Infinera and Lumentum have validated Infinera’s portfolio of DWDM platforms over Lumentum’s white box optical line system.

The interoperability testing included Infinera’s XTM Series, Cloud Xpress Family and DTN-X Family (including XTC and XT Series) platforms. In addition, the companies successfully conducted interoperability testing of Infinera’s next generation Infinite Capacity Engine pilot hardware.

Specifically, the Infinera platforms interoperated with the Lumentum white box open line system including the 20 port Transport ROADM. The test cases covered point-to-point metro fiber links carrying multiple modulations including QPSK (quadrature phase shift keying), 8QAM (quadrature amplitude modulation) and 16QAM with PIC based super-channels over the Lumentum open line system. The test was able to fill the fiber to full capacity at QPSK, 8QAM and 16QAM data rates via 19 super-channels injected into a single rack unit 20 port ROADM. A fully loaded solution achieves up to 24 terabits of fiber capacity using the Infinite Capacity Engine at 16QAM. The testing successfully validated standard optical parameters including optical signal to noise ratio (OSNR) for seamless performance over metro distances.

The companies described the interoperability testing as the first multi-vendor driven demonstration of, and commitment to supporting, an open, interoperable and agile approach to the construction of transport networks, including for data center interconnect (DCI) and metro/edge WDM transport.

Infinera and Lumentum also noted that they are collaborating on open packet optical transport in the Telecom Infra Project (TIP), an industry initiative co-founded by Facebook.

“By validating the industry’s first white box open line system interoperability with Lumentum, Infinera has demonstrated our commitment to delivering the innovative and open optical solutions that our customers need,” said Tom Fallon, Infinera CEO. “Infinera’s leadership in technology innovation with large-scale photonic integration is changing telecom networks. This announcement is yet another step in the path to delivering on our vision of enabling an infinite pool of intelligent bandwidth that the next communications infrastructure is built upon.”

“Lumentum’s award-winning optical white boxes are designed for simplicity and scalability, with open interfaces to enable Software Defined Networking (SDN),” said Alan Lowe, Lumentum CEO. “The demonstration of successful interoperability with Infinera validates the open system approach that should deliver the simplicity and service innovation many network operators desire.”

Nokia Bell Labs Achieves 65 Tbps for Transoceanic Cable Systems

Alcatel-Lucent Submarine Networks (ASN) and Nokia Bell Labs have achieved record transmission capacity over a 6,600 km single mode fiber.

The lab trial demonstrated a total 65 Tbps transmission using submarine grade dual band erbium doped fiber amplifiers, which will help extend the capability of transoceanic cable systems to meet increasing data traffic demand. The trial leveraged Bell Labs' new Probabilistic Constellation Shaping (PCS) technology, a new modulation technique that maximizes the distance and capacity of high-speed transmission in optical networks. Unlike traditional techniques whereby all constellation symbols are transmitted with the same occurrence, PCS intelligently uses non-uniform transmission of constellation symbols by reducing the occurrence of high power symbols, thus providing more resilience to noise and other impairments, and the ability to dynamically adapt to changing conditions.

"The future digital existence where everyone, everything and every system and process is connected will require a massive increase in network capacity and the ability to dynamically optimize this capacity. Probabilistic Constellation Shaping extends the limits of current optical transmission by utilizing novel modulation techniques to dramatically improve the performance and capacity needed for the new digital era that will be enabled by the Future X Network," stated Marcus Weldon, president of Nokia Bell Labs & Nokia CTO.

NEC Carries Record 34.9 Tbps over 6,300km of Fiber

NEC has demonstrated a transmission capacity of 34.9 terabits per second (Tbps on a single optical fiber over a distance greater than 6,300 km.

The results, which were presented earlier this year at OFC 2016 in California, broke previous the spectral efficiency record for transoceanic transmission of 7.1 bit/s/Hz, achieving 8.3 bit/s/Hz using the C-band spectrum. This is a 16.9% improvement on the previous record.

NEC said this level of capacity comes very close to the Shannon limit, which is the fundamental spectral efficiency limit of optical communications. In fact, the demonstration came within 0.5 decibels (dB) of the theoretical maximum value.

"We are proud to have come so close to Shannon's cornerstone of communication theory," said Toru Kawauchi, General Manager of the Submarine Network Division at NEC Corporation. "NEC's research and development teams will continue to explore the limits of even greater subsea capacity, flexibility, and cost-effectiveness."

Nokia Supplies IP/MPLS + DWDM for Swissgrid

Nokia supplied an IP/MPLS network overlaid on an optical network to Swiss electricity transmission system operator Swissgrid for the management of its electrical grid, which has a length of 6,700 km covering 140 substations. The "Grid Control Network" additionally interconnects power plants, data centers and offices.

In a turnkey project, Nokia implemented two IP/MPLS -based networks, one an operational network and the other a business communications network. They are both overlaid on an encrypted DWDM and Coarse Wavelength Division Multiplex (CWDM) network, also from Nokia. The IP/MPLS network features Nokia's 7705 Service Aggregation Router portfolio, with features tailored to support critical applications required by utilities as well as the 7750 Service Router portfolio. The xWDM network layer, based on the Nokia 1830 Photonic Service Switch, provides optical intrusion detection and on-the-fly low latency wavelength encryption for the operational and business communications network. This means that potential physical intrusions on the fiber cable can be detected and located. In case of an intrusion, sensitive data are nevertheless protected through embedded optical layer encryption (AES-256).

Nokia said its solution is supporting mission-critical operational services such as Supervisory Control and Data Acquisition (SCADA) systems, Teleprotection, video surveillance via closed-circuit TV (CCTV), site access control and intrusion detection. This will allow Swissgrid to maintain the highest level of reliability, safety and security across the entire grid. The network is also enabling business communications between electricity substations and Swissgrid locations for tasks such as office local area network (LAN) and voice over IP (VoIP) in a highly secure way.

When fully deployed in partner sites outside of Switzerland in 2016, the "Grid Control Network" will be the key element in the exchange of electricity between Swissgrid's network in Switzerland and sites in Germany, Austria, Liechtenstein, Italy and France.

BT Tests 5.6 Tbps Optical Transmission Speed

BT and Huawei demonstrated speeds of 2 Tbps over a live core network spanning 700km between London and Dublin.

Separately, BT also announced today that it has successfully transmitted speeds of 5.6Tbps over a single optical fibre running on its trial network between the BT Labs in Adastral Park and the BT Tower in London, beating the previous record of 3 Tbps set in 2014.

Key technical facts about the trials:

  • The 2Tbps trials exploit commercial flexible grid hardware and real-time flexible rate 64GBaud transponders. 64GBaud optical technology runs at twice the electrical speed of current deployed core optical network optical signals and is one of the key enablers for high-speed, long reach optical transmission.
  • The live trials were conducted over a 727km commercial flexible grid optical core link between London and Dublin, based on Huawei’s OSN 9800/8800 and iManager U2000 platforms, carrying live 40/100G customer traffic. The link includes a 133km long unrepeatered submarine cable link from Dublin to Holyhead.
  • The trials demonstrate, for the first time, the successful operation of real-time 64GBaud flexible-rate transponders allowing all-optical, long reach (unregenerated) superchannel transmission, with low latency.
  • In addition, by exploiting flexible rate transponders, BT successfully demonstrated fast capacity turn up (or network upgrade) equivalent to ~2Tbps in one minute.
  • BT and Huawei also successfully demonstrated a record real-time 5.6Tbps optical superchannel over a closed loop network running between the BT Tower and Adastral Park. This comprised 28 x 200Gb/s (64GBaud/QPSK) sub-channels, bundled together to provide combined capacity, achieving highest capacity and spectral efficiency.

Howard Watson, CEO of BT Technology, Service & Operations, said: “BT scientists built the first commercial single mode optical fibre link back in 1984 and the BT Labs remain at the forefront of photonics research more than thirty years later. The core network is the superhighway of the internet. It’s important that our core networks keep pace with the growth in bandwidth demands driven by take-up of high-speed fibre broadband, HD content, 4G smartphones and tablets and in the future, 5G services. So we’re investing in our core, as well as in high-speed access technology such as fibre broadband, to make sure there is no capacity crunch and deliver the best possible speeds to customers.

#OFC2016: Lumentum Targets Optical Whiteboxes for SDN

Lumentum (formerly JDSU) unveiled an "optical whitebox" platform for data center & metro/edge DWDM transport.

Lumentum said its SDN optical whitebox platform will consist of family of configurable building blocks with open interfaces for integration into SDN controller/orchestrator layers, enabling system integrators and network operators to deploy and turn-up services. The initial products based on this SDN whitebox platform target simple point-to-point DCI applications, as well as ROADMs (for metro edge DWDM transport). These include:

Terminal Amplifier: The terminal amplifier whitebox and its associated mux/demux form the endpoints of a transport link.  It supports two high-power variable gain EDFAs, OSC termination, optical channel monitor, and automatic line protection within a 1RU network element.

Mux/Demux: The mux/demux is a passive element that provides the entry/exit point for data transmission channels. The device requires no external power or management connections.  Inventory data for the device is visible through its associated terminal amplifier.

Line Amplifier: The line amplifier whitebox is used to extend system reach beyond the single span limit of the terminal amplifier whitebox. It combines all necessary functions to support amplification in two directions into a single 1RU network element.

ROADM: The ROADM whitebox is used to support wavelength agility in meshed networks. It supports a TrueFlex twin 1xN (9-20+) or single 1xN (2-9) wavelength selective switch, two high power variable gain EDFAs, OSC termination, and optical channel monitor within a 1RU network element.

“SDN optical whiteboxes are another example of Lumentum partnering with customers to anticipate, construct and deliver solutions they need to fulfill the relentless demand for higher performance, higher density, and lower cost,” said Madhu Krishnaswamy, director, product line management, Optical Communications. “The platform is customizable, and supports the addition of updated features for dynamic market conditions.”

Cisco Brings High-Density TDM to Optical Transport

Cisco rolled out a number of enhancements to its optical transport portfolio including high-density time-division multiplexing (TDM) to IP/MPLS capabilities.


Some highlights:

Cisco Network Convergence System (NCS) 4200 Series: Part of the Cisco Evolved Programmable Network (EPN), this transport system addresses network inefficiencies with high-density circuit emulation technology located at the network edge. It converts TDM services into pseudowires that facilitate transport over highly scalable MPLS core networks. With this technology, service providers can keep their existing operational models and service revenue while running all services over IP and retiring their older networks. Service providers can reduce space and power required over existing solutions by up to 90 percent.

Multi-service line card for the Cisco NCS 4000 Series - a new, multi-service line card that doubles slot bandwidth to 400Gbps, while providing port-by-port, pay-as-you-grow flexibility for OTN, Packet, MPLS and Coherent DWDM service. When deployed in the Cisco NCS 4009 and NCS 4016 platforms, chassis density doubles to 3.6Tbps and 6.4Tbps, respectively. The NCS 4000 Fabric is also enhanced to help enable unprecedented in-service scale from a single Cisco NCS 4000 chassis (6.4Tbps) to a Multi-Chassis solution capable of delivering over 100Tbps of capacity leveraging Cisco’s multi-chassis leadership.

Increased density and flexibility for the Cisco NCS 2000 Series: New XPonder line card provides 400 Gbps of client and 400 Gbps of trunk capacity to Cisco’s widely deployed optical transport platform. The XPonder supports OTN, packet and coherent DWDM while contributing significantly to cost reduction – one line card for any mix of DWDM, gray, OTN and packet services.

Cisco NCS 1000 data center interconnect solution - commercial shipment is now underway. Cisco said the DWDM solution is now in trials with 9 top cloud providers.

“We are committed to offering service providers the technology to transform their network architectures and achieve the operational efficiency, scale, and reliability needed to succeed in the digital age,” said Bill Gartner, vice president of optical systems, access routing and transceivers group, Cisco. “We are confident that our new innovations in packet optical convergence will enable our customers to transform their networks today while positioning them to face the challenges and leverage the opportunities presented by a future dominated by the Internet of Things.”

Cisco also confirmed that Verizon will deploy the Cisco NCS Series on portions of its 100G metro network.
