Method and apparatus for calculating configuration of optical transmission network, and optical transmission network system

A computing device, comprising:

• a memory configured to store computer-executable instructions;
• and
• one or more processors coupled to the memory and configured to execute the computer-executable instructions to:
• acquire an initial value of an input power of an optical cable;
• based on the initial value of the input power of the optical cable, obtain an output power of each channel at the end of a section of the optical cable according to a loss of the optical cable;
• take 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
• calculate 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.
