ABSTRACT:
In a long-distance high-speed optical communication scheme in which multiple optical amplifiers are provided at a large number of stages in optical fibers, an optical signal from a light source which has a desired small line width and oscillates at a single wavelength is modulated at a high speed by an external modulator and then transmitted in the fibers which are dispersion shifted optical fibers, the zero-dispersion wavelength in which is set to be larger than the oscillation wavelength of the light source. Therefore, noises and the modulation instability, which would occur due to the phase fluctuation in the oscillation wavelength of the light source, and the influence of a waveform distortion due to the dispersion in the optical fibers can be avoided to make it possible for the first time in history to transmit the optical signals at the high-speed in the long-distance optical communication system employing the optical amplifiers.
