Optical transmission system and control method
An optical transmission system includes multiple multiplexers connected in series and each multiplexing an optical signal and given signal light. Each of the multiplexers includes a multiplexing unit that multiplexes the given signal light that is subject to multiplexing and a second optical signal of a frequency that is adjacent to the frequency of a first optical signal that is included in the given signal light; a monitoring unit that monitors deviation between timings of the first optical signal that is included in the signal light multiplexed with the second optical signal by the multiplexing unit, and the second optical signal; and an adjusting unit that based on a result of monitoring by the monitoring unit, adjusts the timing of the second optical signal that is to be multiplexed with the given signal light, by the multiplexing unit.
