Abstract :
We demonstrate a transmission of 4/spl times/2.5-Gb/s spectrum-sliced incoherent wavelength-division-multiplexed channels over 240 km of dispersion-shifted fiber. The channel bandwidth and the channel spacing are kept small using the intrachannel four-wave mixing at the receiver. The error-floor level is close to 1/spl times/10/sup -11/ and the dispersion penalty is within 1 dB at 1/spl times/10/sup -9/ bit-error rate. Eye opening simulation shows that incoherent channels are less sensitive to the fiber four-wave mixing than coherent channels.
