Comcast tests Lumenisity's hollowcore fiber

Wednesday, April 20, 2022 Comcast, Fiber, hollowcore, Optical

Comcast confirmed its first deployment of advanced hollowcore fiber optics.

Comcast connected two locations in Philadelphia, which enables network engineers to continue to test and observe the performance and physical compatibility of hollowcore fiber in a real-world deployment. Comcast successfully tested bidirectional transmission (upstream and downstream traffic traveling on a single fiber), used coherent and direct-detect systems (allowing for forward and backward technology compatibility), and produced traffic rates ranging from 10 gigabits per second (Gbps) to 400 Gbps all simultaneously on a single strand of hollowcore fiber.

Comcast believes its 40-kilometer hybrid deployment of hollowcore and traditional fiber to be the longest in the world by an Internet provider.

“Hollowcore fiber is a leap forward in how we deliver ultra-fast, ultra-low latency and ultra-reliable services to customers,” said Elad Nafshi, EVP & Chief Network Officer at Comcast Cable. “As we continue to develop and deploy technology to deliver 10G, multigigabit performance to tens of millions of homes, hollowcore fiber will help to ensure that the network powering those experiences is among the most advanced and highest performing in the world.”

“We are proud to be working with Comcast on the next generation hollowcore fiber, which we believe unlocks exciting new potential for connectivity around the world,” said David Parker, Executive Chairman of Lumenisity.

Lumenisity unveils Hollow Core Double Nested Antiresonant Nodeless Fiber

Thursday, March 10, 2022 Fiber, Lumenisity

Lumenisity Limited, a start-up based in Romsey, United Kingdom, announced a new generation of hollowcore fibre with the lowest attenuation of any hollowcore fibre reported to date. The company says its new product surpasses the attenuation of conventional germanium-doped single-mode fibre (SMF) in the O and C bands. Specifically, Lumenisity’s new Hollow Core Double Nested Antiresonant Nodeless Fiber (DNANF) achieves attenuations of <0.22...

BT begins testing hollow core fibre

Tuesday, June 01, 2021 BT

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...

euNetworks connects LSE with hollowcore fibre from Lumenisity

Thursday, April 15, 2021 Eunetworks, Hollowcore, Lumenisity, Start-Ups, UK

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...

BT tests Quantum Key Distribution over hollow core fibre

Monday, September 13, 2021 BT, hollowcore, Quantum

BT has conducted a trial of Quantum Key Distribution (QKD) over hollow core fibre cable developed by Lumenisity, a spin out from Southampton University.

Testing of Nested Anti-Resonant Nodeless Fibre (NANF) hollow core fibre kicked off this summer at the BT Labs in Ipswich.

BT researchers operated a state-of-the-art QKD system using commercial equipment over a 6-kilometre-long Lumenisity CoreSmart cable with a hollow, air-filled centre, revealing potential benefits such as reduced latency and no appreciable crosstalk – the effect of a transmitted signal interfering with the transmission of another signal.

Professor Andrew Lord, BT’s Head of Optical Network Research, said: “This is an exciting milestone for BT, accelerating the UK’s lead in quantum technologies that will play an important role in future communications systems globally. We’ve proven a range of benefits that can be realised by deploying hollow core fibre for quantum-secure communication. Hollow core fibre’s low latency and ability to send QKD over a single fibre with other signals is a critical advancement for the future of secure communications.”

Tony Pearson, VP Sales and Marketing at Lumenisity, said: “We are excited to be identifying new applications for our field deployable CoreSmart cable solutions and working with the BT team on the first trial in the world of this kind. This milestone further accentuates not just the capability of our hollow core cable solutions, offering low latency and high bandwidth, but also demonstrating the potential CoreSmart has in new applications thanks to ultra low non-linearity and dispersion across a broad spectrum, perfect for networks operated by our Carrier partners.”

ADVA brings post-quantum cryptography to optical transport

Thursday, July 08, 2021 ADVA, Quantum

ADVA announced post-quantum cryptography (PQC) capabilities for its optical transport solution.The FSP 3000 ConnectGuard optical encryption solution relies on a hybrid key exchange system, combining PQC algorithms with classical encryption methods. It utilizes the traditional Diffie-Hellman protocol and combines it with a newly developed algorithm based on the quantum-safe McEliece cryptosystem. This enables it to produce encryption keys that even...

Planning begins for a European quantum communication network

Monday, May 31, 2021 Europa, Quantum

The European Commission has selected Airbus to lead a consortium of companies and research institutes to study the design of the future European quantum communication network, EuroQCI, to enable ultra-secure communication between critical infrastructures and government institutions across the European Union. The 15-month study will set out the details of the end-to-end system and design. The European Commission's ambition is to run a EuroQCI demonstrator...

Colt tests quantum-based super-encryption with ADVA

Tuesday, February 16, 2021 ADVA, Quantum

Colt Technology Services has successfully conducted a field trial of quantum-secured transport using ADVA's FSP 3000 platform with ConnectGuard Layer 1 encryption technology. The trial, which was conducted over Colt’s deployed metro network in Frankfurt, utilized quantum key distribution (QKD) to super-encrypt live data traffic. ADVA’s partner ID Quantique also played a key role in the trial. Colt harnessed the ADVA FSP 3000, which receives...

euNetworks connects LSE with hollowcore fibre from Lumenisity

Thursday, April 15, 2021 Eunetworks, hollowcore, Lumenisity, Start-ups, UK

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.”
