| Abstract: | In this paper, based on optical pulse signal type and characteristics in optical receiver for dig- ital optical fibcr communication, the uniformization of is given by using transmission characteris- tic of uniformed amplifier and equalige filter. Cosine ware is sccured for output wave of amplifier and equalized filter. Some paramters of cosine wave are obtained. Then, with the relation between noise of PD- JT optical receiver and these parameters, the approximate analysis result for noise can be dran. |
