euNetworks deploys Lumenisity's hollow-core fiber cable in London

April 19, 2021
The partners say the news marks the first broad-based deployment by a carrier of hollow-core fiber to a trading venue, offering a live route more than 30% faster than existing fiber-based routes.
euNetworks Fiber UK Limited, a Western European bandwidth infrastructure company, announced it has deployed its first ultra low latency cable system based on Lumenisity Limited's CoreSmart NANF [nested antiresonant nodeless fiber] hollow-core fiber technology.

Lumenisity supplied the CoreSmart cable solution, with the new deployment now conducting live data traffic between Interxion: A Digital Realty Company, and the London Stock Exchange.

According to the partners, the announcement marks the first commercially available deployment of the NANF hollow-core fiber technology in the world, and is part of an agreement covering additional deployments over the coming years between trading venues and other locations. According to Lumenisity, "Data travels 50% faster in hollow-core cable, reducing latency by 1/3, and providing a round trip saving of 3μs per km. These latency savings are very significant in financial trading applications."

The company further contends that hollow-core fiber cables "can also be scaled to increase the separation of data centers by 50%, while maintaining the latency envelope, more than doubling the area of land in which these data centers can be located." With deployments in numerous private networks over the last three years, Lumenisity contends its CoreSmart is the lowest loss, broadest bandwidth hollow-core cable currently available commercially.

Lumenisity Limited was formed in early 2017 as a spin out from the University of Southampton to commercialize breakthroughs in the development of hollow-core optical fiber. Lumenisity, NANF and CoreSmart are registered trademarks of Lumenisity Limited.

“We’re very pleased to partner with euNetworks to enable them to provide the lowest latency performance to a major trading exchange using our CoreSmart cable,” said Tony Pearson, business development director at Lumenisity. “We are excited to be collaborating with such an established carrier and to already have hollow-core deployed, carrying traffic as part of this development.”

As a critical bandwidth infrastructure company, owning and operating 17 fiber based metropolitan networks connected with a high capacity intercity backbone covering 51 cities in 15 countries, euNetworks is among the market leaders in delivering fiber-based ultra low latency services throughout Europe. euNetworks is also a leading cloud connectivity provider and offers a targeted portfolio of metropolitan and long haul services including dark fiber, wavelengths, and Ethernet. The provider bills its euTrade solution as a dedicated network platform supporting the bandwidth needs of the financial services community. The company says it continues to optimize routes between all the key trading exchanges in Europe to ensure delivery of the shortest paths and lowest latencies available in the market.

“We continue to focus on delivering lowest latency services for our customers. We focus on identifying new and innovative technologies that can be deployed on our network to provide the best possible bandwidth solutions,” said Brady Rafuse, chief executive officer of euNetworks. “We’re excited to be working with Lumenisity, helping to develop and deploy hollow-core fiber. We’re confident that with this technology we can achieve market leading fiber-based latencies much closer to radio frequency systems, without the constraints that are inherently present with those radio frequency solutions.”
