Impact of Intercore Crosstalk on Achievable Information Rates

We investigate the impact of intercore crosstalk in a 7-core fiber on signal to noise ratio and achievable information rates for PDM-QPSK, PDM-16QAM, and PDM-64QAM formats. The achievable rate is reduced by 8%, 5.4% and 1.5%, at a crosstalk of −25.6dB/100km respectively
