QSFP-DD800 MSA releases initial 800G transceiver spec

The Quad Small Form Factor Pluggable Double Density 800 (QSFP-DD800) Multi Source Agreement (MSA) group has released a new hardware specification for the QSFP-DD800 transceiver form factor.

The new QSFP-DD800 1.0 specification is intended to be incremental to the existing QSFP-DD 5.0 specification. As signal integrity and thermal performance remain imperative, the transceiver pads have been optimized to improve signal integrity for 100 Gbps performance per lane without affecting backwards compatibility. The new specification additionally defines a novel 2x1 connector/cage, with cabled upper ports as an option to address signal loss issues associated with tradition PCBs. Looking ahead, QSFP-DD800 promoters will continue to work on new connector/cage variants, including 2x1 SMT versions that operate at 100 Gbps per lane.

The MSA group was formed to advance the development of high-speed, double-density QSFP modules which support 800 Gbps connectivity and includes the following promoters: Broadcom, Cisco, II-VI, Intel, Juniper Networks, Marvell, Molex and Samtec.

“In the short time our group has collaborated, we are thrilled to introduce this first specification for the next generation of the QSFP family of modules,” said Scott Sommers, co-chair of the QSFP-DD800 MSA. “As signal integrity and thermal management remain challenges for the optical communications industry, our MSA group is confident that its solutions will meet performance needs.”

“With their superior system integration and design flexibility, QSFP modules continue to be the cornerstone in building next generation networks and network equipment, especially as port speeds increase to 800G,” said Mark Nowell, co-chair of the QSFP-DD800 MSA. “Furthermore, their ability to increase switch and routing bandwidth density without sacrificing backwards compatibility with QSFP-DD, QSFP56 and QSFP28 modules provide network operators tremendous commercial and operational advantages.”

Verizon carries 800 Gbps wavelength

Verizon reported the transmission of 800 Gbps of data on a single wavelength over its live network.

The test showed equipment interoperability from two different suppliers and the capability to quadruple the typical capacity carried on a wavelength. The test traffic was transmitted between two Juniper Networks QFX 5220 packet platforms across two Ciena 6500 platforms powered by WaveLogic 5 Extreme (WL5e) coherent optics.

Verizon said the use of this new coherent optics and equipment from Ciena and Juniper demonstrates the evolution to a more software-driven and automated network with tunable capacity from 200Gbps to 800Gbps per wavelength.\

“In the past, we needed to combine multiple wavelengths to achieve 800 Gbps capacity,” said Kevin N. Smith, Vice President of Technology and Planning for Verizon. “Now, with the new optics configuration from Ciena and Juniper Networks on our fiber network, we are advancing our connecting layer of fiber to prepare for the explosion of data we know will come along with 5G’s transformational impact on industries and consumers. And being the only provider in the industry with that capacity on a single wavelength allows us to deliver the service at a much lower cost per bit.”

“800G is possible today with our WaveLogic 5 Extreme technology and this live Network trial is remarkable because it shows the progression of capacity and efficiencies,” said Scott McFeely, Senior Vice President of Global Products and Services for Ciena. “Programmable 200Gbps-800Gbps transmission will allow Verizon to effectively respond to fluctuating user demands by creating a more software-driven, programmable and highly scalable network.”

“As network traffic continues to grow sharply, driven by video and other new 5G uses cases, it’s imperative for communications service providers and infrastructure vendors to work closely together for rapid innovation. New 400GbE packet routers and 800G coherent optical systems help drive down the cost per bit with improved scale and density. We’re excited to have played a role in this successful trial and look forward to help deliver new, high-bandwidth services to end-users.” - Sally Bament, Vice President, Cloud & Service Provider Marketing, Juniper Networks.

Verizon will begin deploying this new optical configuration in the fiber network in the second half of 2020.

Southern Cross Cable carries first 800G wavelength

Southern Cross Cable connected the first single-wavelength 800G across a live production network using Ciena’s WaveLogic 5 Extreme (WL5e) coherent optics.

Specifically, the new 800G channel speed ran error-free on Southern Cross’ live production network between two large, global data centers on the U.S. West Coast and demonstrated record-breaking spectral efficiencies.

Ciena said Southern Cross will begin volume deployment of WL5e in the second calendar quarter of 2020 across various segments of its network, including Trans-Pacific submarine cables and terrestrial cables across U.S. West Coast and New Zealand.

“As many internet service providers are looking to the submarine cable industry to provide reliable connectivity to their customers, leading operators like Southern Cross need networks that can adapt to fluctuating connectivity demands. With WaveLogic 5, we are delivering the industry’s first 800G solution and reinforcing our leadership in providing the highest performance optics in the market,” stated Rick Seeto, Vice President and General Manager of Asia-Pacific and Japan, Ciena.


Construction begins on Southern Cross NEXT Cable

The Southern Cross NEXT project has achieved CIF (Contract in Force) status and has entered the construction project phase.

The Southern Cross NEXT submarine cable is a state-of-the-art 4 fibre pair undersea route utilising an open cable design and enhancing the existing Southern Cross eco-system. The system will also provide full fibre connectivity to Auckland, New Zealand, and will incorporate Branching Units (BU) and OADM technology for connections to Fiji, Tokelau and Kiribati. Given its robust design and route including branches, the 16,148km cable system will provide the lowest latency path from Australia and New Zealand to the United States. 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.”
