BT, the UK’s largest telecoms and network provider, has launched hollow core fiber trials at the BT Labs in Adastral Park, Ipswich, in a joint venture with Lumenisity, the University of Southampton’s spin-off company and Mavenir, the Open Radio Access Network (O- RAN) mobile carrier.   The research is being carried out at BT’s research and engineering facilities, with the researchers using a 10-kilometer-long hollow-core fiber cable made by Lumenisity. This state-of-the-art network cable has a hollow, air-filled center that extends through the entirety of the cable. The hollow core fiber will be tested for a myriad of applications, such as the possible benefits to 5G networks and highly secure communications such as Quantum Key Distribution (QKD).   Reducing the latency of hollow fiber light could provide immense benefits, including high-frequency trading and reduced mobile network costs. This joint venture has revealed that the usage of hollow core fiber can…
