Inter-Core Crosstalk in Multicore Fibers: Impact on 56-Gbaud/λ/Core PAM-4 Transmission

Abstract

We experimentally demonstrate the impact of inter-core crosstalk in multicore fibers on 56Gbaud PAM-4 signal quality after 2.5-km transmission over a weakly-coupled and uncoupled sevencore fibers, revealing the crosstalk dependence on carrier central wavelength in range of 1540-1560 nm.
