Abstract :
An electronic scheme for joint postcompensation of fiber and semiconductor optical amplifier (SOA) impairments based on coherent detection and digital backward propagation is proposed and demonstrated. A 10-GBd amplitude-phase-modulated transmission system was demonstrated experimentally using semiconductor optical amplification. The Q-factor of the received signal was improved by 5 dB with simultaneous fiber and SOA impairment compensation in the electrical domain.
