Abstract	:	In low dispersion fibers, the four-wave mixing (FWM) spectrum is symmetric withrespect to the zero-dispersion wavelength. This thesis analyzes a wavelength shiftkeying (WSK) technique. a modification of the standard wavelength divisionmultiplexing (WDM) system. WSK uses symmetric wavelength assignment andbalanced detection to cancel FWM crosstalk to first order. Error probabilities forboth dispersion shifted fiber and non-zero dispersion shifted fiber were calculatedusing Gaussian approximation. WSK out-performs standard onsff WDM at allsignal power levels and allows a larger bit rate-distance product for a given BERrequirement. Four-Wave mixing in a long-haul transmission scenario was simulatedin an experimental testbed. BER measurements compared well with thecalculations and proved that WSK is indeed noise tolerant.....-...,..tested for theQ1 PC1 bus cardBoth these projects mere sofixare des elopment efforts tonards contributing to dlfferentaspects of Roboucs and lZ1echatronics projects m the Controls and Roboucs Group..
