BT kicked off trials of hollow core fibre at the BT Labs in Adastral Park, Ipswich, in a collaborative project with Lumenisity, a Southampton University spin out company, and Mavenir.
BT researchers are conducting the trials at BT’s research and engineering campus, using a 10-kilometre-long hollow core fibre cable provided by Lumenisity. The new fibre has a hollow, air filled centre that runs the entire length of the cable. It will be used to test a variety of use cases, including potential benefits for 5G networks and ultra-secure communications, like Quantum Key Distribution (QKD).
BT notes that single-mode optical fibre was pioneered at Adastral Park. Research into hollow core fibre presents an opportunity to explore how the capabilities of optical fibre can be enhanced in future, with the potential to reduce the latency, or signal delay, caused by the light travelling through glass, by up to 50%. This new fibre has an air-filled central core, with an outer ring of glass, to guide the laser beam whilst maintaining the signal speed at very close to the ultimate speed of light.
Professor Andrew Lord, BT’s Head of Optical Network Research, said: “We’re excited to begin trialling hollow core fibre and to discover the potential opportunities and benefits of deploying this technology in certain scenarios. This new type of fibre cable could play an important role in the future of the world’s communications infrastructure, heralding a step-change in capability and speed, to keep up with the demands for high-speed, low latency communications driven by 5G networks, streaming, and more.”
Mike Fake, Lumenisity’s Director responsible for Product Management, said: “Lumenisity is delighted to be the supplier of field deployable CoreSmart hollowcore cable for these trials with BT. This is further evidence of the impact our unique low loss, high performing cables can have on the networks operated by our carrier partners.”
John Baker, Mavenir’s Senior Vice President Business Development, said: “The ability to extend the reach of fibre connected radios only further demonstrates the power of Open RAN and its Eco System. This improvement will significantly increase the number of use cases that can be served from containerised cloud-based Open RAN solution.”

euNetworks connects LSE with hollowcore fibre from Lumenisity
Lumenisity Limited, a start-up based in Romsey, United Kingdom, supplied its ultra low latency CoreSmart cable solution based on “NANF” hollowcore fibres, to euNetworks Fiber UK. The fibre route connects an Interxion data center with the London Stock Exchange.
Lumenisity Limited, which was formed in early 2017 as a spin out from the University of Southampton, said data travels 50% faster in hollowcore 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.
euNetworks offers a fibre-based, dedicated network platform supporting the bandwidth needs of the financial services community.
“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 hollowcore deployed, carrying traffic as part of this development.”
“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 hollowcore fibre. We’re confident that with this technology we can achieve market leading fibre-based latencies much closer to radio frequency systems, without the constraints that are inherently present with those radio frequency solutions.”
