Windstream carries 800G wavelength over 730km using Infinera

Windstream successfully achieved 800 Gbps single-wavelength transmission over 730 kilometers across its long-haul network between San Diego and Phoenix. The test used Infinera’s fifth-generation coherent optical technology, ICE6 (Infinite Capacity Engine), equipped in a Groove (GX) Series platform over industry-standard G.652-compliant SMF-28 fiber. By looping back the signal, the test also achieved a 700G transmission over 1,460 km.

The record performance was enabled by advances in Nyquist subcarriers, a pioneering innovation developed by Infinera’s Optical Innovation Center (OIC). Nyquist subcarrier-based solutions map the traffic into tightly packed, lower-baud-rate digital subcarriers within a single optical carrier. Infinera says subcarriers also amplify the benefits of its other OIC innovation, such as 64QAM long-codeword probabilistic constellation shaping and dynamic bandwidth allocation.

The companies said the trial demonstrates that ultra-high-speed optical transmissions, such as 700G and 800G, can be deployed in real-world network applications over significant distances. This will enable emerging 400 Gigabit Ethernet (400 GbE) services to be supported over longer distances within the Windstream national network. High-performance, high-speed transmission will also enable network operators like Windstream to realize increased efficiency in cost per bit and power per bit, as well as increased capacity per fiber by as much as 70 percent compared to third-generation (400G) coherent technology and by as much as 35 percent compared to fourth-generation (600G) coherent technology.

“Windstream remains committed to staying at the forefront of technological innovation and the superior performance of ICE6 brings real-world value to our network and enables us to meet the explosive growth in bandwidth demands of our customers,” said Buddy Bayer, chief network officer at Windstream. “The flexibility of ICE6 coupled with the easily deployable compact modular form factor of the GX Series will enable Windstream to quickly and easily introduce this new technology across our entire network from edge to core.”

“Infinera is delighted to set this new industry benchmark and partner with Windstream, a network operator that continually pushes the boundaries of optical networking,” said Parthiban Kandappan, chief technology officer at Infinera. “As proven by the superior performance of this network trial, we believe our unique expertise with Nyquist subcarriers coupled with the groundbreaking innovations introduced by ICE6 will represent the standard for high-speed optical engines going forward.”

Ethernet Technology Consortium focuses on 800G

The 25 Gigabit Ethernet Consortium, originally established to develop 25, 50 and 100 Gbps Ethernet specifications, has changed its name to the Ethernet Technology Consortium in order to reflect a new focus on higher-speed Ethernet technologies, the 800GBASE-R specification for 800 Gigabit Ethernet (GbE).

The 800 GbE specification introduces a new media access control (MAC) and Physical Coding Sublayer (PCS). It essentially re-purposes two sets of the existing 400GbE logic from the IEEE 802.3bs standard with a few modifications in order to distribute the data across eight 106 Gb/s physical lanes. As the PCS is reused, the standard RS(544, 514) forward error correction is retained, for simple compatibility with existing physical layer specifications.

The Ethernet Technology Consortium said its goal is to enhance the Ethernet specification to operate at new speeds by utilizing specifications that are developed or in development. This allows the organization to work alongside other industry groups and standards bodies to adapt Ethernet at a pace that aligns with the rapidly evolving needs of the industry. The ETC has more than 45 members with top-level promoter members that include Arista, Broadcom, Cisco, Dell, Google, Mellanox and Microsoft.

“Ethernet is evolving very quickly and as a group, we felt that having 25G in the name was too constraining for the scope of the consortium,” said Brad Booth, chair of the Ethernet Technology Consortium. “We wanted to open that up so that the industry could have an organization that could enhance Ethernet specifications for new and developing markets.”

“The intent with this work was to repurpose the standard 400GbE logic as much as possible to create an 800 GbE MAC and PCS specification with minimal overhead cost to users implementing multi-rate Ethernet ports,” said Rob Stone, technical working group chair of the Ethernet Technology Consortium. “The 800 GbE specification is an exciting first announcement under the consortium’s new name, reflecting the true capability of the organization. We are proud of the hard work of our member companies in completing this specification.”

Low latency spec for 50GbE tweaks forward error correction

Tuesday, February 19, 2019  25G, 50G, Specs, Standards  

The 25 Gigabit Ethernet Consortium has completed a low-latency forward error correction (FEC) specification for 50 Gbps, 100 Gbps and 200 Gbps Ethernet networks.

The new spec cuts FEC latency approximately in half by using a shortened codeword FEC variant – RS (272, 257+1, 7, 10) that replaces the IEEE 802.3cd and 802.3bs standard FEC.  The shortened codeword contains 272 x 10-bit symbols rather than the 544 x 10-bit symbols originally specified. Nothing else changes in the symbol distribution process from the output of the encoder to the FEC lanes in the new FEC, but that process is implemented more quickly due to the shortened codeword.

This will have a significant impact on overall physical layer latency, in particular for hyperscale datacenter networks comprised of a large number of nodes, with multiple hops between servers.

“Five years ago, only HPC developers cared about low latency, but today has latency sensitivity has come to many more mainstream applications,” said Rob Stone, technical working group chair of the 25G Ethernet Consortium. “With this new specification, the consortium is improving the single largest source of packet processing latency, which improves the performance that high-speed Ethernet brings to these applications.”

The specification is available at https://25gethernet.org/ll-fec-specification

Organisers said Southern Cross NEXT represents a network investment of around US$300 million. It is designed to carry 72 terabits per second of traffic. Completion is targetted for the end of 2021 or early 2022.

“The achievement of CIF is a testament to the hard work of the combined Southern Cross and Pioneer Consulting team over many months and is a validation of the technology and expertise behind the new cable,” said Southern Cross President and CEO, Laurie Miller. “The addition of the Southern Cross NEXT route to our platform will provide existing and future customers with further resiliency and connectivity options between Australia, New Zealand and the United States.”

ADVA hits new benchmarks for bandwidth/reach on terrestrial long-haul

ADVA announced new benchmarks for bandwidth and reach on terrestrial long-haul using its FSP 3000 TeraFlex platform.

The new records were achieved in a commercial long-haul terrestrial network originally built for 100Gbit/s services. ADVA’s partners included the Poznan Supercomputing and Networking Center (PSNC), EENet of HITSA and Tele2 Estonia.

Using an optical spectrum-as-a-service approach, the terminal achieved 200Gbit/s per wavelength transmission over a distance of 5,738km with 2.5bit/symbol, and 500Gbit/s over 1,016km with 5bit/symbol modulation. Record-breaking results also included 300Gbit/s per wavelength transmission over 3,751km with 3bit/symbol, and 400Gbit/s per wavelength across 1,792km with 4.5bit/symbol modulation. Feasibility of 800Gbit/s transmission over 1,016km in a single 125GHz spectral slice was also demonstrated.

ADVA said one of the keys to achieving this performance is the ability of the FSP 3000 TeraFlex to utilize network telemetry and fractional QAM to maximize reach and capacity through the automated configuration of modulation format and baud rate.

The trial also highlighted how a disaggregated open line system (OLS) approach can enhance network flexibility and leverage the most value from existing optical infrastructure.

“Our terminal technology is now redefining terrestrial long-haul data transport. Just as we proved in trials with DCI and metro networks, the software-defined transmission of our FSP 3000 TeraFlex™ is the ultimate response to soaring bandwidth needs,” said Jörg-Peter Elbers, SVP, advanced technology, ADVA. “With its programmable signal shaping and ultra-flexible modulation capabilities, our unique solution balances distance and capacity for maximum spectrum utilization and optimal performance over any reach. This gives communication service providers the power to massively increase bandwidth without the expense of a major upgrade. This demo also shows how an open coherent optical layer removes all restrictions, even when interconnecting across multiple countries. And, with our FSP 3000 TeraFlex deployed as part of a disaggregated OLS solution, it delivers complete agility for best cost efficiency.”
