发明名称 Optical transmission device and optical transmission method
摘要 An optical transmission device includes: a switching configured to be capable of switching a transmission path to which light is input from a first transmission path to a second transmission path; a first calculation unit configured to calculate, based on a difference between a first light level of the first transmission path and a second light level of the second transmission path, a first control amount for the second light level; and a control unit configured to perform a first control in which the second light level is decreased or increased based on the first control amount upon switching of the transmission path.

主权项 1. An optical transmission device comprising: a switch configured to be capable of switching a transmission path for transmitting light from a first transmission path to a second transmission path; a first calculation unit configured to calculate, based on a difference between a first light level of the first transmission path and a second light level of the second transmission path, a first amount for controlling the second light level; and a control unit configured to perform, upon switching of the transmission path, a first control in which the second light level is decreased or increased based on the first amount by switching from performing a first feedback control in which the first light level is decreased or increased based on a second amount calculated based on the first light level.
