摘要: Cross-phase modulation impairment resonances exist in wavelength-division-multiplexed lightwave systems when channels are spaced such that there occurs an integral number of bit walkthroughs per amplifier span. We have observed these transmission through 624-km standard single-mode fiber having span lengths 40, 80, or 120 km. Q measurements a 2.5-Gb/s five-channel system over 8/spl times/80 km with +7 dBm/channel predict on-resonance bit-error rates (BER's) several orders magnitude higher than off-resonance BER's.
