Abstract:
We investigate the coexistence of quantum key distribution (QKD) and classical transmission in a field-deployed uncoupled-core four-core fiber. We experimentally characterize inter-core spontaneous Raman scattering, finding that QKD is feasible in one core with 25-dB channel loss, with three cores used for full C-band transmission.
