Title:
OPTICAL SELECTIVE SWITCH AND NODE DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/227545
Kind Code:
A1
Abstract:
The embodiments of the present application provide an optical selective switch and a node device, relating to the field of optical communications, for improving the increase of the number of WSS ports, resulting in the problem that the maximum deflection angle of an emission beam of a diffraction grating is large. The optical selective switch comprises N input ports, M output ports, an input passive deflection element, an input active deflection element, an output passive deflection element, and an output active deflection element. Each input port is used to receive input light. Each output port is used to output, from the output port, light to be outputted. The input passive deflection element is used to deflect the input light to a corresponding direction of an intermediate output port. The input active deflection element is used to deflect the input light to a corresponding direction of a target output port according to the deflection of the input passive deflection element. The output passive deflection element is used to deflect, to the direction corresponding to the intermediate output port, the light to be outputted. The output active deflection element is used to deflect, to the target output port according to the deflection of the output passive deflection element, the light to be outputted.
