Submarine optical communication control device, control method, and non-transitory computer-readable medium

A submarine optical communication system control method comprising:

• determining an optimum distribution of signal light intensity of an optical path for each allocated frequency;
• measuring a light intensity distribution of an optical path after transmission through a submarine cable transmission line;
• calculating a gain equalization setting for compensating for a difference between an optimum distribution of a light intensity distribution and a measured distribution of an optical path after transmission;
• and
• compensating for a light intensity distribution of an optical path to the optimum distribution, based on the gain equalization setting.

A non-transitory computer-readable medium storing a program for causing a computer to execute:

• a light intensity distribution determination procedure for determining an optimum distribution of signal light intensity of an optical path for each allocated frequency;
• an equalization setting calculation procedure for calculating a gain equalization setting for compensating for a difference between the optimum distribution and a measured distribution of light intensity measured for an optical path after transmission through a submarine cable transmission line;
• and
• an equalization setting notification procedure for notifying a setting for compensating for a light intensity distribution of an optical path to the optimum distribution, based on a gain equalization setting in the equalization setting calculation procedure.
