DWDM transmission of 128Gb/s PM-16QAM signal over 1815km of 7-core MCF using shared carrier reception for improving the received signal quality

We demonstrate SCR method with 1815km transmission of 128Gb/s PM-16QAM over 7-core MCF using ECL. Frequency offset compensation of SCR enables demodulation and tolerates more than 10% path difference. Phase noise compensation of SCR enables to extend the transmitted distance, when using DFB, up to 1650km provided precise skew adjustment.
