Abstract
We demonstrate an optical multiplexing and transmission of QPSK-to-16QAM channels over 100 km using wave mixing for aggregation and noise mitigation. For the input signals with phase noise of ~50, 35 degree and 300 MHz noise bandwidth, the OSNR penalty of ~1dB is obtained at BER 10−3 for aggregated 20 Gbaud 16QAM signal compared to the case of having no phase noise in input signals.
