Abstract

Fiber fiber-wave mixing (FWM) is studied for multichannel multi-amplifier systems composed of short fibers with different zero-dispersion wavelength. An analytical expression describing FWM in these systems is derived. Using the expression, crosstalk is calculated for various combinations of fiber lengths, which are selected according to a random function, and allowable fiber input power is evaluated. The results show that the allowable input power for nonuniform dispersion is larger than that for uniform dispersion by several dB, depending on system conditions
