TL;DR
This paper experimentally demonstrates that quantum key distribution can coexist with 112 Gbps data transmission in multicore fibers, ensuring telecom compatibility through proper core and wavelength allocation.
Contribution
It provides the first experimental validation of QKD co-existing with high-speed data in multicore fibers with trench-assistant structures.
Findings
QKD can coexist with 112 Gbps data in multicore fibers
Proper core and wavelength allocation ensures telecom compatibility
Experimental validation in both non-trench and trench-assistant fibers
Abstract
We experimentally characterize photon leakage from 112Gbps data channels in both non-trench and trench-assistant 7-core fibers, demonstrating telecom compatibility for QKD co-existing with high-speed data transmission when a proper core/wavelength allocation is carried out.
