PURPOSE: To provide an optical fiber transmission line formed in such a manner that the wavelength dispersion of the transmission line and the waveform distortion by a Kerr effect are nearly completely offset by taking a change in the light intensity of the transmission line into consideration. CONSTITUTION: A second optical fiber 4 is virtually divided to 1st, 2nd...n-th microsections from a phase conjugation converter 8 to a signal receiver 10 and a first optical fiber 2 is virtually divided to the 1st, 2nd...n-th microsections from the phase conjugation converter 8 to the transmitter. The core diameters of the first and second optical fibers are so determined that the ratio of the wavelength dispersion value to the product of the light intensity and the constant of the Kerr effect in the 1st to n-th microsections of the first optical fiber is made equal to the ratio of the wavelength dispersion value to the product of the light intensity and the constant of the Kerr effect in the 1st to n-th microsections of the second optical fiber. The lengths of the respective microsections are so determined as to be propartioned to the inverse number of the product of the light intensity and the constant of the Kerr effect in the microsections or the inverse number of the wavelength dispersion value. |
