A method for selecting a light source for optical communication system comprises the steps of measuring time division chirping characteristics and optical response waveforms of the light source responding to a fixed strength random pulse signal; performing a simulation of a transmission process based on measured data; computing a selection parameter as an index for determining a dispersion tolerance quality of the light source according to a computed post-transmission waveform of an optical signal that propagated through an optical fiber path; and deciding the dispersion tolerance quality of the light source based on values of the selection parameter. There is no need for providing the usual facilities required for dispersion tolerance evaluation such as EDFA, optical fibers, wavelength filter, receiving disk and error rate detector and the like and the time required for selection is significantly reduced.
