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: A ferrule includes a ferrule matrix, an optical fiber, and a dielectric reflective film. The optical fiber is disposed in an accommodating through hole of the ferrule matrix, and the dielectric reflective film covers an optical transmission surface of the optical fiber and a surface that is of the ferrule matrix and that faces a matching ferrule. The dielectric reflective film has a through hole, such that the dielectric reflective film does not shield a main optical path area of the optical transmission surface of the optical fiber. A reflective band of the dielectric reflective film includes at least a part of a communication band of the optical fiber. In this way, when light from the matching ferrule is transmitted to the ferrule matrix and the optical fiber, the dielectric reflective film reflects the light.

Abstract: Example optical connector ferrules and example optical connectors are provided. An example optical connector ferrule is a first ferrule of an optical connector, where the first ferrule includes n optical channels, and the first ferrule is configured to be compatible with a second ferrule. The second ferrule includes m optical channels, where both m and n are positive integers, and n is greater than m. The n optical channels of the first ferrule include first-type optical channels and second-type optical channels, where an arrangement manner of the first-type optical channels is the same as that of the m optical channels of the second ferrule, and at least one of the second-type optical channels is located in at least one of rows in which the first-type optical channels are located.
