Wavelength division multiplex optical signal regeneration method |
摘要 |
A wavelength division multiplex optical signal regenerator is inserted between two optical fiber sections of a wavelength division multiplex fiber optic transmission system including a transmission line made up of a plurality of optical fiber sections and providing N channels at different wavelengths where N is an integer greater than 1. The regenerator includes a demultiplexer for demultiplexing wavelength division multiplexed optical signals onto N individual channels, and a multiplexer for multiplexing optical signals at the output of the N individual channels into multiplexed optical signals. Each individual channel includes a saturable absorber for reshaping the optical signals of each channel, and a delay line. The length of each delay line is chosen to introduce a total delay taun'' between the (n+1)th channel and the nth channel to obtain a time shift of taun between the (n+1)th channel and the nth channel.
