摘要： An optical wavelength multiplex transmission method uses a band around a zero dispersion wavelength of an optical fiber to compensate for waveform degradation, which is produced by a synergetic effect of self phase modulation and chromatic dispersion, to increase transmission distance and transmission rate in optical systems. The optical dispersion compensation method is performed in an optical system including a transmitter, a repeater and a receiver, which collectively transmit and receive optical information along the optical fiber. Light is transmitted within a transmissible band which is defined by an allowable dispersion value determined from a synergetic effect of self phase modulation and group velocity dispersion in the optical fiber. The transmissible band is set on a shorter wavelength side than a shorter wavelength end .lambda..theta.-.DELTA..lambda..theta. or on a longer wavelength side than a longer wavelength end .lambda..theta.+.DELTA..lambda..theta. of the zero-dispersion wavelength deviation range of the optical fiber. The zero dispersion wavelength .DELTA..theta. of the optical fiber is shifted to apparently arrange the signal light into the transmissible band to compensate for the dispersion amount of the optical transmission system.

摘要： In a dispersion compensation quantity setting technique for use in a WDM transmission system, a transmitting terminal node transmits CW light and modulated light obtained by modulation using a modulation pattern signal, while a receiving terminal node detects a physical quantity stemming from cross phase modulation occurring between the transmitting terminal node and the receiving terminal node on the basis of a variation of an intensity of the transmitted CW light and sets a dispersion compensation quantity on the basis of a variation of the detected physical quantity. Moreover, this optimizes the crosstalk, suppresses the output power of transmitted light, eliminates the nonlinear optical effect of the transmitted light, and carries out dispersion compensation superior in cost performance.
