1. an optical transmission method carries out digital modulation at transmitting terminal to light pulse, transmits in optical fiber transmission line, in light-receiving device it is transformed to the signal of telecommunication, it is characterized in that,By the optical Fourier transform device that before light-receiving device, is provided with, make the shape that is transformed to its frequency spectrum through the time waveform of the light pulse after the optical fiber transmission line transmission, the character of utilizing this spectral shape to be saved is thus removed all linear session distortions that light pulse is subjected in optical fiber, reproduce original signal waveform at receiving terminal.
