Integration of Quantum Key Distribution in a 20-km 32-user Coherent Passive Optical Network with Single Feeder Fiber
arXiv:2412.16104
Abstract
We demonstrate for the first time the integration of O-band polarization-encoding decoy-state BB84 QKD into a C-band 20-km single-feeder fiber 32-user coherent PON running at carrier-grade power levels without modifying existing PON infrastructures.
