摘要: front page image
(EN) The embodiment of the invention provides a method and a device for inhibiting the pilot signal crosstalk, and a pilot signal receiving apparatus. The method comprises: obtaining the downloaded amount of currently accumulated dispersion of a multi-wavelength channel optical signal, wherein the downloaded multi-wavelength channel optical signal carrys at least two pilot signals; according to an SRS crosstalk target value, link configuration information, the at least two pilot signals' frequencies and amplitude values, determining an amount of a target accumulated dispersion required to satisfy the SRS crosstalk target value; determining the amount of dispersion needed to adjust, according to the amount of a target accumulated dispersion and the amount of currently accumulated dispersion; and according to the amount of dispersion needed to adjust, controlling the current downloaded multi-wavelength channel optical signal for dispersion accumulation. According to the embodiment of the present invention, the SRS crosstalk suppression of the pilot signals can be controlled to the desired extent.
