Paper Abstract

. The performance of an optical wavelength-division multiplexed system is analyzed taking the four-wave mixing (FWM) effect into account. The efficiency of FWM generation is observed to greatly reduce if the spacing between channels is made unequal. However, the scheme requires an increased bandwidth, which can further be reduced by utilizing another scheme called repeated unequal channel spacing. Also the FWM efficiency is found to reduce in the presence of chromatic dispersion. Use of nonuniform chromatic dispersion along the fiber length, which reduces the FWM effect while maintaining a low value of dispersion is investigated. Various other dispersion management mechanisms are also considered in addition to different channel spacing schemes to achieve a comparative study as to which scheme gives the best solution to the FWM problem.
