碩士 === 中華大學 === 電機工程學系碩士班 === 88 === The wavelength-division-multiplexing (WDM) optical fiber communication system with incomplete dispersion compensations are studied. During signal transmission, signal pulse width of each channel may be compressed or broadened by the combined effect of the dispersion, self-phase modulation and cross-phase modulation. A formula is derived to estimate the root-mean-square (rms) pulse width of WDM system in the absence of amplifier noise during signal transmission. Exact rms pulse width is numerically solved to compare with the rms pulse width estimated by the formula. Using the derived formula, the effect of the cross-phase modulation on the WDM system is clearly understood. With amplifier noise, system performance is evaluated by Q factor. By proper post dispersion compensation, the improvement of system performance in each channel is studied, and the design rules of the WDM system are found.
