Abstract: In the wavelength selective switch provided in the present invention, at least one optical element is successively arranged in the wavelength selective switch according to a sequence of processing optical signals. The at least one optical element receives a service optical signal from a service laser, receives a monitoring optical signal from a monitoring laser, and performs same optical signal processing on the service optical signal and the monitoring optical signal according to a processing function of the at least one optical element, where a wavelength of the service optical signal and a wavelength of the monitoring optical signal are different. A service optical signal processed by the at least one optical element and a monitoring optical signal processed by at least one optical element are output, where the monitoring optical signal processed by the at least one optical element is used for monitoring performance of the wavelength selective switch.

Abstract: An optical communication device includes a dispersion unit and a switching unit that are disposed in a cavity of a closed housing. The optical communication device further includes a monitoring unit and a drive unit. The monitoring unit may monitor in real time offsets of light spots formed on the switching unit. The drive unit can drive the switching unit based on a variation obtained by the monitoring unit, so that the switching unit compensates for the offsets of the light spots. In addition, the optical communication device may further include a dustproof and waterproof unit and a humidity control unit.

Abstract: An optical transceiver, including a coupling assembly and a condensing assembly, is provided. The coupling assembly includes a first surface and a second surface; and multiple first lenses are disposed on the first surface. The condensing assembly includes a fastener, multiple filters, a reflector, and a light passing region; the condensing assembly is fastened to the second surface; the filters are optically aligned with the first lenses separately; the coupling assembly receives light of different wavelengths; and the light of different wavelengths enters the fastener through the multiple filters and is multiplexed or demultiplexed by the reflector and the filters, and multiplexed or demultiplexed light enters the coupling assembly through the light passing region. The optical transceiver provided in the present invention has advantages of low power consumption and high coupling efficiency.
