ABSTRACT:
An optical telecommunication system has at least two sources of optical modulated signals at different wavelengths in a predetermined transmission wavelength band, together with a multiplexer for the signals, an optical fiber line connected at one end to the multiplexer, and a demultiplexer/receiver for the signals. The line comprises an optical fiber having a chromatic dispersion value lower than a predetermined value in the transmission wavelength band and increasing as wavelength increases. The fiber also has a zero value of chromatic dispersion at a wavelength lower than the minimum wavelength of the transmission wavelength band by such an amount that no local wavelength zero value of the chromatic dispersion present in the fiber and capable of generating a four-wave-mixing phenomenon is included in the band.
