摘要
We present a new suppression technique of the transmission impairments caused by cross-phase modulation in dispersion-managed links. This technique can be implemented through a simple, passive, and integratable device. Experimental results show a sensitivity penalty reduction from 4.3 to 0.1 dB in a two-channel 10-Gb/s transmission over three spans of 100-km positive nonzero dispersion-shifted fiber. We also show numerically the potential merits of the device with a large number of channels, merits which are expected to become more evident with the number of spans.
