ABSTRACT:
An optical transmission line formed by a plurality of transmission circuits each comprising, connected in the following order, an optical fiber, an optical amplifier and an optical filter. The dispersion decrease in each optical fiber and the amplification of each optical amplifier are set for each transmission circuit such as to obtain a predetermined optical pulse width, the central frequencies of the optical filters are made to sequentially slide toward lower frequencies along the direction of propagation, and the mean zero-dispersion wavelengths of the optical fibers are made to sequentially increase along the direction of propagation. An optical transmission system according to the present invention is formed from an optical transmission line according to the present invention, an optical transmitter and an optical receiver.
