ABSTRACT:
There is disclosed a super-high speed light transmission method making use of quasi-solitons in a fiber. Chirped stationary pulses are transmitted through the fiber. At a position where the effect of the chirp becomes weak and the sign of the chirp reverses, the sign of the chirp is reversed by a dispersion compensation fiber or fiber grating connected to the fiber in order to recover the initial chirp. The dispersion profile of each of the fibers is properly controlled in order to produce stationary quasi-solitons having a stable pulse shape. The method can prevent widening of pulses, which would otherwise occur due to dispersion.
