SupplyWelength selection switch
The welength selection switch (WSS) is a crucial device in optical communication networks. Through precise optical structures and control mechanisms, it enables precilection and flexible scheduling of optical signal welengths. The working principle of WSS mainly relies on the diffraction effect of gratings and the switching function of optical switches. It can output the selected welength signal to the designated output port from multiple input welength signals, providing dynamic optical path management for optical communication networks.
