Abstract:
1. A dispersion compensation quantity setting method for use in a wavelength-multiplexing optical transmission system including a transmitting terminal station and a receiving terminal station and made to transmit wavelength-multiplexed light, said method comprising: a transmission step in which the transmitting terminal station transmits continuous-wave light and modulated light obtained by modulation using a modulation pattern signal, wherein the modulated light is a wavelength different from a wavelength of said continuous-wave light; a detection step in which said receiving terminal station detects a physical quantity of a variation in intensity of said continuous-wave light transmitted in said transmission step, wherein the physical quantity corresponds to an amount of cross phase modulation being incurred by said continuous-wave light; and a dispersion compensation quantity setting step in which said receiving terminal station sets a reception dispersion compensation quantity on the basis of a variation of said physical quantity detected in said detection step.
