Germany's M-net tests Nokia's probabilistically shaped wavelengths

M-net Telekommunikations GmbH, a German service provider, has conducted the first field trial of probabilistically shaped wavelengths using Nokia Photonic Service Engine 3 (PSE 3) super coherent technology. 

Specifically, M-net and Nokia enabled a 500 Gbps, single, probabilistically shaped wavelength over a regional DWDM network spanning the German state of Bavaria.

M-net used probabilistic constellation shaping (PCS) to shape the signal from its maximum capacity of 600G to a rate optimized for the specific fiber route used in the test.

Dr. Hermann Rodler, CTO at M-net, said: "This field trial clearly underlines the innovative strength of M-net. We are very proud to collaborate with Nokia to push the technology envelope on our state-of-the-art fiber-optic network, and to be the first carrier to publicly test the PSE-3 and its probabilistic constellation shaping technology."

Sam Bucci, head of optical networking at Nokia, said: "We're excited to partner with M-net on the implementation of its new fiber optic backbone network. The Technical University of Munich played a key role in the development of PCS, and the PSE-3 was largely developed at Nokia's R&D facility in Nuremberg, so it's only appropriate that the first field trial of PSE-3 technology would take place in Bavaria."

Nokia's PSE-3 chipset leverages probabilistic constellation shaping

Nokia unveiled its Photonic Service Engine 3 chipset featuring probabilistic constellation shaping (PCS) that pushes fiber-optic performance close to the Shannon limit to fully exploit channel capacity.

PCS is a new modulation technique pioneered by Nokia Bell Labs that the company says enables maximum capacity over any distance and on any fiber - from metro to subsea - increasing capacity up to 65% over currently deployed networks while reducing power by 60%. This includes 200G rates over most terrestrial and subsea links, as 400G over most shorter distances.

The PSE-3 chipset, which is the first coherent digital signal processor to implement PCS, provides finely adjustable wavelength capacity from 100G to 600G with a single, uniform modulation format, baud rate, and channel size. This simplifies network operations and planning.

"This is a breakthrough in how we can maximize the performance of optical networks and, at the same time, vastly simplify operations. The Photonic Service Engine 3 is the culmination of a decade of research and first-hand experience building the largest, highest capacity optical networks in the world. By introducing this extreme and yet remarkably simple programmability, our customers can now maximize the capacity of every link in their network, whether that's 10 km, 10,000 km or beyond. They will be able to keep their costs under control while handling the huge bandwidth demands that video, cloud, and soon 5G will be throwing at them."

Nokia is planning to introduce the PSE-3 chipset across ist packet-optical portfolio, including a new version of the 1830 Photonic Service Interconnect, a compact modular WDM platform for data center interconnect. The 1830 PSI-M will use modular chassis architecture with high-performance modules based pm the PSE-3. Commercial availability is expected in Q3 2018.

Fujitsu demos 600G single wavelength optical transmission

Fujitsu Network Communications announced the first demonstration of flexible 600 Gbps single wavelength optical transmission using its 1FINITY T600 Transport platform. Software-provisioned data rates up to 600 Gbps per wavelength were achieved by a combination of high-performance components and electronics on the T600, maximizing spectral efficiency and reach for optimized network performance.

Specifically, Fujitsu publicly demonstrated error-free 600 Gbps transmission using 64QAM modulation at 69 Gbaud and 75GHz grid spacing in a point-to-point configuration. Service turn-up and onsite reprovisioning of signal rates and modulation formats were achieved among 300 Gbps, 400 Gbps and 600 Gbps. Fujitsu’s FSS2 system software provided OpenConfig over gRPC Network Management Interface (gNMI) for system configuration, streaming telemetry for network monitoring, and enhanced diagnostics. The demonstration showcased a 600G 64QAM live constellation shown on a Fujitsu-built vector signal analyzer.

The 1FINITY T600 is powered by third-generation digital signal processor (DSP) technology developed by NTT Electronics (NEL) in partnership with Fujitsu. The plaform delivers sophisticated and flexible modulation schemes and variable forward error correction (FEC). The advanced modulation flexibility provides optimum reach, capacity and power consumption, thereby enabling network operators to reduce cost per bit per kilometer for data center interconnect (DCI), metro, long-haul and submarine applications.

“At OFC 2018, Fujitsu was the first optical vendor to exhibit 500G per lambda,” said Rod Naphan, Deputy Head of the Network Products Business Unit at Fujitsu. “This week’s public demonstration of 600G further validates our leadership in next-generation coherent technology and positions us to bring the 1FINITY T600 to market in 1Q19.”

The Fujitsu 600 Gbps single wavelength optical transmission demonstration occurred during the NANOG 74 conference in Vancouver, British Columbia, on October 1-3, 2018.

NeoPhotonics shows 64 GBaud for 600G and 1.2T coherent transport

NeoPhotonics is currently shipping a suite of 64 GBaud optical components for coherent systems operating at 600G and 1.2T.  64 GBaud components double the symbol rate over standard 100G (32 GBaud) coherent systems.

The NeoPhotonics suite use three optical components to enable single channel 600G or dual channel 1.2T transmission:

  • 64 GBaud CDM -- NeoPhotonics 64 GBaud, polarization multiplexed, quadrature coherent driver modulator (CDM) is shipping in limited availability and features a co-packaged InP modulator with a linear, high bandwidth, differential driver in a compact package designed to be compliant with the anticipated OIF Implementation Agreement. Co-packaging the InP IQ modulator with the driver enables an 85% reduction in line card board space compared to equivalent lithium niobate solutions. Furthermore, this facilitates transceiver applications up to 600 Gbps on a single wavelength for next-generation transport modules..
  • 64 GBaud Micro-ICR -- NeoPhotonics Class 40 High Bandwidth Micro-Intradyne Coherent Receiver (Micro-ICR) is in volume production and is designed for 64 GBaud symbol rates, doubling the RF bandwidth of standard 100G ICRs. The 64 GBaud Micro-ICR supports higher order modulation such as 64 QAM. The compact package is designed to be compliant with the OIF Implementation Agreement OIF-DPC-MRX-02.0.
  • Low Profile Micro-TL -- NeoPhotonics ultra-narrow linewidth external cavity tunable laser has been proven in volume production and is now configured in a smaller, lower profile package, which is designed to meet the stringent requirements for packaging density in pluggable modules. The external cavity laser design has a significantly narrower linewidth than competing designs, which is especially advantageous for higher order modulation formats. The laser is available in a compact package Integrable Tunable Laser Assembly form factor designed to be compliant with the OIF Implementation Agreements OIF-MicroITLA-01.1 and OIF-ITLA-MSA-01.3.

NeoPhotonics said its solution supports transmission over data center interconnect (DCI) distances of up to 80 km. The components also support 400G over metro distances of 400-600 km using 64 GBaud and 16 QAM or 200G over long-haul distances of greater than 1000 km using 64 GBaud and QPSK.

“All three elements of our suite of optical components for 600G and 1.2T are now available and shipping to customers, allowing them to take advantage of the performance of all three elements to optimize their system performance,” said Tim Jenks, Chairman and CEO of NeoPhotonics. “We ensure that each element is designed to work seamlessly with the others and offer our customers a complete optical solution, both increasing performance and reducing development time” continued Mr. Jenks.
