We show demodulation and demultiplexing of multi-channel WDM differential phase-shift-keying (DPSK) signals operating simultaneously at 10 Gb/s and 40 Gb/s using a 1x4 wavelength selective switch. We achieve error-free performance for four channels equally spaced by 100 GHz propagated over an 85 km dispersion-compensated link. We study the advantages and limitations of this new DPSK demodulator compared with the conventional delay-line interferometer.
我们展示了使用1x4波长选择开关对同时以10 Gb/s和40 Gb/s运行的多通道波分复用差分相移键控（DPSK）信号进行解调和解复用。我们在85公里的色散补偿链路中，实现了四个等间隔100 GHz的通道的无差错性能。我们研究了这种新型DPSK解调器与传统延迟线干涉仪相比的优点和局限性。
