Crosstalk Impact on a 535 Tb/s 172 km Transmission Using a Homogeneous 19-Core Multicore Fiber

We show the feasibility of a 535 Tb/s link with 172.8 km reach using a 19-core homogeneous multicore fiber. We demonstrate an average crosstalk penalty below 0.25 dB, enabling the transmission of 115×24.5 Gbaud PDM-64QAM signals in the C-band.
