Problems solved by technology

This way of sending light limits the distance between the original LD ​​laser 1-2 and the original fiber optic assembly. However, the commonly used optical transceiver integrated single-fiber bidirectional optical device is a miniaturized packaged optical device, and the interface of the original LD ​​laser will occur during use. The outward deviation causes the light beam emitted by the light source device to be unable to enter the optical fiber channel through the refraction of the coupling lens, which affects the efficiency of photoelectric transmission

Abstract

The invention discloses a novel optical transmitting-receiving integrated single-fiber bidirectional optical device. The optical transmitting-receiving integrated single-fiber bidirectional optical device comprises an optical device shell, optical transmitting-receiving equipment, an equipment mounting plate, a light adjusting assembly and a beveled edge wave absorbing block, wherein the optical transmitting-receiving equipment comprises an LD laser, an optical fiber assembly and an optical detector, the LD laser is provided with a first convex lens, and the light adjusting assembly comprisesa 45-degree reflector and a second convex lens. The two convex lenses are used for solving the problem that a light beam of a single-fiber double-wire component cannot normally enter an optical fiberchannel due to outward deviation of the LD laser.

Description
