Characteristics of All-0ptical Regenerator Using Fiber Kerr Gate

The mechanism of using fiber Kerr gate regenerator to suppress the additive noise and timing jitters of input optical signal is discussed. Influences of parameters of different components in the regenerator on the abilities of pressing noise in input signal are analyzed. It's shown that the regenerator can greatly suppress noise in communication system and improve its communication capacity by choosing suitable length of DSF in I}err gate according to the noise characteristics in system.
