Inter-Core Crosstalk Penalties in Wideband WDM, MCF Transmission Over Transoceanic Distances

We measure a strong wavelength-dependence transmission-distance penalty from inter-core crosstalk in an MCF transmission system using 350 PDM-QPSK channels across 80nm spectrum, ranging from 12.5% (short $C$-band) to 60% (long $L$-band) and maximum distance of 10,000km.
