Abstract
Each optical transmission device includes a detecting unit, a notifying unit, and a control unit. The detecting unit detects a value of the optical power of each of multiple wavelengths. The notifying unit notifies an optical transmission device at the upstream side of a control frame that includes the value and that includes information that indicates the execution state of the optical power control. The control unit calculates the adjustment level on the basis of the optical power of each of the wavelengths detected by the detecting unit. Furthermore, when the information included in the control frame sent from an optical transmission device at the downstream side indicates that the optical power control is being stopped, the control unit calculates the adjustment level on the basis of the value included in the control frame and executes optical power control by setting the calculated adjustment level to the optical device.
