Optical Communication Device

An optical communication device, comprising:

• an optical interface comprising:
• an input port configured to input an optical signal, wherein the optical signal comprises light sub-beams of a plurality of wavelengths;
• and
• output ports configured to output deflected light sub-beams;
• a closed housing disposing the optical interface and comprising:
• a cavity configured to receive the optical signal from the input port;
• a disperser disposed in the cavity and configured to:
• disperse the optical signal into the light sub-beams on a dispersion plane;
• and
• transmit the light sub-beams;
• and
• a switching system disposed in the cavity and comprising partitions configured to:
• receive the light sub-beams from the disperser to form light spots on the partitions;
• deflect the light sub-beams on switching planes according to preset angles to obtain the deflected light sub-beams;
• and
• transmit the deflected light sub-beams to the output ports;
• a monitor configured to monitor offsets of the light spots on the switching system;
• and
• a driver connected to the switching system and the monitor and configured to drive the switching system to compensate for the offsets.
