Optical transceiver module and optical receiving assembly

Abstract

Disclosed are an optical transceiver module and an optical receiving assembly. The optical receiving assembly includes an optical fiber socket for receiving signal light, an optical fiber which is provided with a receiving end, an emitting end and a connection section between the receiving end and the emitting end, wherein the receiving end is fixed to the optical fiber socket and the emitting end is provided with a reflection inclined plane, and a shell which is provided with an accommodation cavity. The connection section and the emitting end of the optical fiber extend into the accommodation cavity. A fixing base and a circuit board are arranged in the accommodation cavity. The fixing base is provided with a fixing groove. The connection section of the optical fiber is correspondingly fixed to the fixing groove. A photo-detector and an amplifier are arranged on the circuit board. The photo-detector is arranged under the emitting end of the optical fiber. The signal light input from the receiving end of the optical fiber is reflected by the reflecting inclined plane of the optical fiber, enters the photo-detector and then is converted into an electrical signal. The electrical signal is amplified by the amplifier and then output to the outside. The optical transceiver module and the optical receiving assembly help to reduce the insertion loss and return loss of the signal light and increase the transmission rate.

AI Technical Summary

Problems solved by technology

This light-receiving subassembly structure requires the introduction of lenses, optical waveguide components, and lens arrays. The signal beam input from the fiber optic socket needs to be coupled multiple times before reaching the optical sensing element, which increases the insertion loss and return loss of the signal beam. Not conducive to improving the quality of signal transmission
