Transmission of 256Gb/s PM-16QAM Signal through 7-Core MCF and MC-EDFA with Common Cladding and Variable Shared Core Pumping for Reduction of Power Consumption

We transmit 256Gb/s PM-16QAM signal through 385km with 7-core MCF, passing 7 times a MC-EDFA with common cladding and variable shared core pumping. The MC-EDFA enables 23% reduction of power consumption while received Q value varied within ±0.17dB.
