Title:
OPTICAL SIGNAL CONTROL DEVICE AND OPTICAL COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/180822
Kind Code:
A1
Abstract:
An optical signal control device (70) is configured to be provided with a leakage amount calculation unit (83) for calculating a leakage amount of light leaking into each optical signal included in a multiplexed signal from the other optical signals on the basis of an optical intensity measured by a first optical intensity measurement unit (77) and an optical intensity measured by a second optical intensity measurement unit (78), and an attenuation amount calculation unit (84) for calculating an attenuation amount for each optical signal included in the multiplexed signal on the basis of the optical intensity measured by the second optical intensity measurement unit (78) and the leakage amount of light. The optical signal control device (70) is configured such that a wavelength selection switch (71) attenuates each optical signal included in the multiplexed signal in accordance with the attenuation amount calculated by the attenuation amount calculation unit (84).
