Abstract: An optical communication system includes a first component, a second component, and an optical connection assembly that connects the first component and the second component. An example method includes: controlling the first component to send a first optical signal to the second component through the optical connection assembly; sending an alarm indication when it is determined, based on an optical power variation status of the first optical signal in a transmission process, that the optical connection assembly is exceptional; and when it is determined, based on the optical power variation status of the first optical signal in the transmission process, that the optical connection assembly is normal, controlling the first component to send a second optical signal to the second component, where an optical power of the second optical signal is greater than an optical power of the first optical signal.

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.

Abstract: Embodiments of this application provide an optical communication device, including a light-transmitting solid-state medium unit, and further including an input and output unit, a dispersion unit, and a switching unit that are respectively disposed on wall surfaces of the medium unit. An input port of the input and output unit inputs an optical signal into the medium unit and transmits the optical signal to the dispersion unit. The dispersion unit disperses the optical signal into a plurality of sub-beams and transmits the sub-beams to the switching unit. The switching unit deflects, in preset angles, the sub-beams respectively to form a plurality of deflected sub-beams, and enables the deflected sub-beam to be output from the medium unit and transmitted to a corresponding output port. This implements grooming and assignment of wavelengths of the optical signal. This significantly reduces sealing costs and reduces costs and a size of the optical communication device.
