Abstract:
1. An optical transmitter-receiver connected to a single-core optical fiber, comprising: light emitter for emitting first light; light receiver for receiving second light launched from the optical fiber; focusing device for focusing the first light to the optical fiber and the second light to the light receiver; optical-path splitter for splitting the first light emitted from the light emitter to guide the first light to the optical fiber and to guide the second light launched from the optical fiber to the light receiver; and reflector for reflecting a part of the first light, said part returning to the light receiver, said reflector having a fiber-contacting face for allowing the reflector to come in contact with an end face of the optical fiber and a face for reflecting the part of the first light, said face being opposite to the fiber-contacting face.
