Abstract

The invention discloses a single-fiber bi-directional light receiving and emitting device which comprises a TO tube socket, a laser device encapsulated in a TO tube shell, a detector encapsulated in the TO tube shell, lenticulation with different thicknesses and an optical fiber connector. The cross section of the TO tube socket is of a right trapezoid, the right angle surface of the TO tube socket is connected with TO base pins, and the direction of the base pins is parallel to the axial direction of the TO tube shell. The laser device and the detector are welded on the inclined plane of the TO tube socket and are arranged in parallel, and electrode leading wires are led to the base pins from the inclined plane of the tube socket through the whole TO tube socket and are connected with the base pins. The lenticulation with different thicknesses is arranged and fixed obliquely, and the intersection angle between the lenticulation with different thicknesses and the axial direction of the TO tube shell is beta. The laser device emits optical signals, and the optical signals are refracted through the lenticulation with different thicknesses and enter an optical fiber in the optical fiber connector. External light enters the single-fiber bi-directional light receiving and emitting device through the optical fiber, and enters the detector through the refraction of the lenticulation with different thicknesses. Through the utilization of the single-fiber bi-directional light receiving and emitting device, cost is saved, and the welding and mounting of BOSA modules are made to be convenient at the same time.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a single-fiber bidirectional optical transceiver device for optical communication transmission. Background technique [0002] Optical communication technology has become the most important pillar of modern communication and plays a mainstay role in modern communication. At the same time, as an emerging technology that is gradually becoming mature, optical communication has developed rapidly in recent years, which is rare in the history of communication. Optical communication is destined to become the main transmission tool for various information in the future information society. [0003] Single-fiber bidirectional optical transceiver device (Bi-direction Optic Sub-assembly, referred to as BOSA) is a photoelectric conversion device that integrates transmitting and receiving. It can realize the function of bidirectional transmission of data in a single optical fibe...
