Demonstration of 17λ x 10 Gb/s C-Band Classical / DV-QKD Co-Existence Over Hollow-Core Fiber Link

Abstract

We successfully integrate coherent one-way QKD at 1538 nm in a 7.7 km long hollow-core fiber link with 17 EDFA-boosted C-band data channels from 1540.56 to 1558.17 nm, aggregating a power of 11 dBm. QKD operation proves successful despite the wideband layout of classical channels.
