摘要:
Optical wavelength-division multiplexing (WDM) with channel spacing equal to the symbol rate is demonstrated.Coherent detection with subsequent digital signal processing is used for demultiplexing and demodulation. Experimental results for a 6-Gbaud binary phase-shift keying WDM transmission with a 6-GHz channel spacing achieve a Q-factor penalty of 2.8 dB compared to a single-channel transmission.
