BT has started trials of hollow-core fibre optical networks to test if they can raise fixed-line speeds and produce mobile networks with lower latencies.
The telco is performing the trials at its R&D campus in Suffolk s Adastral Park and aims to deploy up to 10km of fibre. It also intends to test the suitability of hollow-core networks for other more niche tasks, such as Quantum Key Distribution (QKD).
BT is working with American OpenRAN vendor Mavenir, as well as Lumenisity a startup spun out from the University of Southampton that specialises in hollow-core fibre networks.

The inaugural RootMetrics 5G Scorecard has identified notable infrastructure improvements over the course of 2021 with the EE network being the standout service in the country.
The mobile network performance benchmark firm’s study measured next-generation network users’ everyday usage experience in four major UK cities in 2021 - London, Bristol, Birmingham and Coventry - offering insights into the most typical end-user 5G experience in the UK cities, that is “everyday” 5G performance. This includes results recorded on both 5G-only technology and 5G mixed-mode, what RootMetrics said was an increasingly common experience for UK consumers of switching between 5G and 4G LTE during the same data service.
