Paper Abstract

In this paper some generalized sub-optimum unequally spaced channel allocation techniques have been suggested for minimizing Four Wave Mixing (FWM) effect in Dense Wavelength Division Multiplexed (DWDM) fiber optic systems. These techniques are sub-optimum because their use will not reduce the FWM noise power generation at the frequencies matching the channel frequency to zero, but these are useful in reducing the FWM noise substantially. The major advantage of our techniques of USCA is that these can be applied to a small as well as a large number of channels with equal ease. Also the use of our techniques will not increase the operating bandwidth requirement of the system under the condition that the minimum inter channel separation used in our allocation technique is not less than the inter-channel separation required for good channel selectivity at the receiver. Efficiency of these techniques in minimizing the detrimental effect of FWM in DWDM fiber optic systems has been studied and compared with that of equally spaced channel allocation systems.
