Press Release

Adtran, the leading provider of next-generation open and disaggregated networking solutions, today announced that it successfully completed a field trial of 800Gbit/s single-carrier transport, achieving error-free transmission over a record distance of 2,220km in NYSERNet’s production network. The test route passed through 14 route-and-select flexgrid ROADMs comprising a total of 28 wavelength-selective switches. Leveraging 140GBd digital signal processing (DSP) technology from Acacia, an industry leader for silicon-based high-speed optical interconnect products, this result was made possible by Adtran’s use of continuous symbol rate tuning and probabilistic constellation shaping offered by Acacia’s Coherent Interconnect Module 8 (CIM 8). The trial showcases an opportunity for network operators to increase capacity and efficiency while minimizing complexity and cost.

“We’ve taken single-carrier 800Gbit/s data transmission further than ever before. And we’ve achieved it not in a lab but in a real-world network also carrying live traffic. What’s more, we succeeded without any optimization to the line system, maintaining the same amplifier settings used before the field trial. We’ve demonstrated that the highest capacity and reach can now be accomplished even over deployed fiber comprising a mix of standard G.652 and G.655 and including multiple network nodes and flexgrid ROADMs,” said Sorin Tibuleac, director of system architecture at Optical Networks, Adtran. “Building on the success of our TeraFlex™ CoreChannel™ technology, these results represent the next milestone in the development of high-speed optical networks. The potential to enhance throughput while minimizing opex and operational complexity is immense.”

Adtran’s trial marks the longest distance ever achieved for 800Gbit/s data transport using a single optical carrier with real-time DSP. To realize this, it utilized Acacia’s CIM 8 transceiver technology, which increases baud rates up to 140Gbd to generate 800Gbit/s signals. By achieving long-distance transmission with single-carrier optics, the demo helps operators reduce footprint and energy consumption. The trial used Adtran’s FSP 3000 open line system (OLS), which provided the necessary flexibility to configure the wider required bandwidth and perform testing. Featuring a modular architecture, multiple amplification and multiplexing options, and different chassis sizes, this truly open OLS enables operators to deploy customized and future-proof solutions.

“We’re pleased to play a key role in this trial and proud of our record-breaking network. Alongside our partners, we’re showing that the highest speeds are now possible over extremely long distances, even in intricate and heterogeneous network environments. This demo reveals a way to address complexity and cost while eliminating the need for expensive and unnecessary infrastructure expansion,” commented Bill Owens, chief network architect at NYSERNet. “The success of this trial offers a major boost to the research and education institutions we support. By working with global leaders like Adtran and Acacia, we’re ensuring that our network can benefit from the latest innovation and keep our academic community at the forefront of scientific research.”

“Our field trial sets a new standard for long-haul, single-carrier data transmission over an existing network with live customer traffic. It shows the full potential of our technology to increase capacity and efficiency while reducing power consumption and expense,” noted Christian Rasmussen, VP of DSP and optics engineering at Acacia. “Our CIM 8 coherent optical module was instrumental in enabling this achievement. Featuring our 8th generation DSP and advanced silicon photonics, the CIM 8 module offers baud rate adjustment up to 140GBd and continuous modulation, which optimizes the use of available spectrum. This gives service providers complete transmission flexibility to match their network’s architecture, improve fiber utilization and simplify deployments.”

Announcements today from ISP Grain, Bath based Truespeed, and B Corp Zen reinforces the sense that there is still plenty going on with the UK’s ambitious smaller telco’s.

Rochdale based broadband provider, Zen, continued to show commitment to its B Corporation certification and Carbon Neutral status, announcing installation of 675 solar panels to the roof of its headquarters office building. This is only stage one, with another 500 panels to follow which should see solar power generate 330 MWh of electricity for the company.

Paul Stobart, CEO at Zen, commented “One way to reduce reliance on fossil fuels is to invest in solar, which is exactly what we are doing at Zen.”

Heading further north, Cumbria-based ISP Grain has secured more funding to assist with plans to roll out fibre-to-the-premises (FTTP) across the North of England. Existing shareholders Equitix, Albion Capital and Pinnacle Group have been joined by funding from Landesbank Nord/LB to take the total capital invested in the business to £200 million.

German Landesbank Nord/LB has committed £110 million, whilst the existing shareholders have are investing an additional £21 million of equity. CFO Roland Barzegar, said ‘This further investment in Grain will see us accelerate the rollout already underway across the country. We have proven that our model of providing fast, reliable and great value broadband is working, and customers are happy that they have more choice outside of the national broadband providers.’

Finally, at the other end of the country, Bath based Truespeed expects progress to come from transformation of internal systems, and to achieve this have looked to BT’s talent pool, hiring Robert Purdy as Chief Information Officer. Prior to joining Truespeed Robert was Director of Consumer IT, responsible for delivering the BT, EE and Plusnet brands across broadband, mobile and television services. He says he was drawn to Truespeed by “how successfully it has grown and how well it’s situated in its current scale-up phase.”

Another well funded business, Truespeed were founded in 2014 and are supported by Aviva Investors who have so far invested £175 million firm, most recently in January 2022.

Richard Tang, Founder and Chairman of Zen Internet will be one of the speakers at the Total Telecom Connected North event, taking place on 17 – 18 April 2023 at Manchester Central.
