Systems of a transmission optical fiber a soliton signals and a wavelength multiplexing)

摘要

The invention relates to an optical fiber transmission system using soliton signals with wavelength division multiplexing, in which the wavelengths (lambda1 to lambdan) of the various channels of the multiplex are chosen so that at least one point of the transmission system, the difference between the bit times of two channels of the multiplex is substantially a multiple of t / n of the clock period. The present invention proposes to arrange at this point a synchronous modulator is used to modulate the soliton signals at a frequency n / t is a multiple of the soliton clock frequency 1 / t. in a diagram of the allocation of frequencies for the synchronization of the bit times of the channels with an interval of zr, it is thus possible to modulate the assembly of the channels at intervals in the multiple zr, at frequencies of modulation is a multiple of the clock frequency.
