FEC overhead optimization for long-haul transmission of PM-16QAM based 400Gb/s super-channel

We optimize the FEC-OH of dual-carrier PM-16QAM 400Gb/s super-channel, considering the tradeoff between FEC net coding gain and performance penalties due to limited DAC/ADC bandwidth. At optimum FEC-OH (-29%), WDM transmission of 400Gb/s super-channel over 2150km LAPSCF is experimentally demonstrated.
