"So you need to amplify less .... It can lead to greener networks if this is how you want to exploit it"
"one of the most noteworthy improvements in waveguided optical technology for the past 40 years"
"a potential revolution in optical communications."
"These are big claims but we truly believe this is a breakthrough,"
A new hollow-core fiber (HCF) design achieves record-low optical loss and higher bandwidth compared with conventional solid-core optical fiber. Light travelling mostly through air reduces propagation delay and cuts latency between datacenters and mobile networks. Lower optical loss reduces the need for amplification, enabling greener networks and cost savings. Faster transmission benefits AI model training, remote surgery, and self-driving cars. Previous HCF iterations suffered impractical losses; the new design claims to overcome these limits. Microsoft and University of Southampton-affiliated teams and the Lumenisity spinoff contributed to development and testing of the design.
