چکیده انگلیسی
In long-haul frequency-division-multiplexing (FDM) lightwave transmission systems, transmission characteristics are degraded by four-wave mixing (FWM) generated in optical fibers. To overcome this problem in equally spaced (ES) allocation, modified repeated unequally spaced (RUS) allocations such as equally spaced RUS (ERUS) and unequally spaced RUS (URUS) allocations have been already examined. Also, it has been shown that FWM noises are decreased by arranging the polarization states of the channels. In this paper, dependence of FWM noises on frequency allocations and polarization allocations is investigated. It is revealed that FWM noises are decreased in ES, RUS, ERUS, and URUS with alternating polarization allocations of the channels, and FWM noises are drastically reduced when light polarizations are perpendicularly crossed at both sides of the zero dispersion frequency.
