OPTICAL TRANSMISSION DEVICE

摘要

This optical transmission device comprises: a demultiplexer (101) for demultiplexing an inputted optical signal into a plurality of wavelength bands; a plurality of optical switches (111-113) corresponding to a plurality of demultiplexed optical signals and configured by light blocking units or variable optical attenuators for transmitting or blocking the optical signals; an optical coupler (120) for multiplexing the optical signals outputted from the plurality of optical switches (111-113); and a control unit (130) for setting the transmission or blocking of the demultiplexed optical signals with respect to the respective plurality of optical switches (111-113).
