Abstract :
Unequal-spaced channel-allocation techniques have been studied to reduce four-wave-mixing (FWM) crosstalk in high-capacity wavelength-division multiplexing (WDM) transmission systems. In this paper, we develop two algorithms that are helpful to system designers in quickly determining the total numbers of FWM crosstalk falling into the operating band and each channel of such WDM systems. By knowing the numbers, one can adjust the system parameters, such as the minimum channel spacing, in order to keep a good balance on the adverse effects of FWM crosstalk and interchannel interference or to avoid the assignment of channels at locations with the worse crosstalk
