Abstract
A submarine optical communication system includes a first submarine device and a second submarine device. The first submarine device includes a first monitoring circuit for monitoring an operation state of the first submarine device and a first optical signal adjusting circuit for adjusting an intensity of an optical signal in a first wavelength band based on a first monitoring result obtained by the first monitoring circuit and outputting the adjusted optical signal as an optical signal including the first monitoring result. The second submarine device includes a second monitoring circuit for monitoring an operation state of the second submarine device and a second optical signal adjusting circuit for adjusting an intensity of an optical signal in a second wavelength band based on a second monitoring result obtained by the first monitoring circuit and outputting the adjusted optical signal as an optical signal including the second monitoring result.
