Intercore crosstalk. The intercore crosstalk at the end of the 4-core fiber, when exciting the modes with the FM-MCF spatial multiplexer at 1550 nm. The intercore crosstalk when exciting a given LP lm mode in a given core, is calculated from the average crosstalk between the given core and each of other cores.
