1. A method for calculating configuration of an optical transmission network, comprising:
acquiring an initial value of an input power of an optical cable;
based on the initial value of the input power of the optical cable, obtaining an output power of each channel at an end of a section of the optical cable according to a loss of the optical cable;
taking the output power of each channel at the end of the section of the optical cable as a boundary condition to calculate the input power of each channel at the section of the optical cable based on an amount of optical power transferred from a high-frequency channel to a low-frequency channel due to an SRS effect; and
calculating a first parameter value of an optical amplifier of the section of the optical cable using the input power of each channel at the section of the optical cable and the output power of each channel at the end of a preceding section of the section of the optical cable.
