Abstract: Optical time domain reflectometers and optical subassemblies haying optical tine domain reflectometry functions are provided. In one aspect, an optical time domain reflectometer includes a base and a light splitting film disposed on the base, and the light splitting film includes a first side corresponding to a transmission region and a second, opposite side corresponding to a reflection region. The optical time domain reflectometer further includes a laser and a detector that are respectively located on the transmission region and the reflection region. The light splitting film is configured to: reflect or transmit laser light emitted by the laser out of the base, and reflect or transmit a part of the laser light reflected or scattered by an optical fiber to the detector.

Abstract: This application provides an optical component including a base, a light splitting structure, a first filter, and a collimation lens, where a first optical signal on a first path is incident on a light splitting surface of the first filter through a light inlet/outlet; the light splitting surface of the first filter reflects the first optical signal to the collimation lens along a second path, where the collimation lens disposed on the second path is configured to convert the first optical signal on the second path into parallel light; and the first optical signal includes a signal of at least one type of wavelength, and the light splitting structure is disposed on an emergent path of the first optical signal after the first optical signal passes through the collimation lens, and is configured to output, based on the wavelength type, the first optical signal adjusted by the collimation lens.
