Description
The wavelength division optical module is inserted into the switch. Each optical module emits light of a specific wavelength. The light emitted by the optical module is connected to the wavelength division multiplexer’s corresponding wavelength mux channel port, and the optical module receiving port is also connected to the wavelength division multiplexer’s corresponding wavelength demux channel port. Each optical module is connected in this way. After the link is connected, the light emitted by each channel optical module is multiplexed into a beam of light, which comes out of the Mux-COM, and the light from the other end enters the Demux-COM.
Features
- Low insertion loss
- Low polarization-dependent loss
