[0041] Such as Figure 9 As shown, the first lens module 4 is integrated with a first lens 9, and the optical fiber carrier 7 is integrated with a second lens 10. The light emitted by the photoelectric conversion chip 32 is collimated through the first lens 9 and passed through the second lens 10. The light received by the fiber group 8 is collimated by the second lens 10 and then focused onto the photoelectric conversion chip 32 by the first lens 9 . At this time, the fiber carrier 7 is perpendicular to the PCB board 5 .

Abstract

A signal transmission optical module comprises a PCB and a first lens module. The first lens module is arranged in a structural frame, a transmission line is arranged in the structural frame, the transmission line is connected with a chipset, the PCB is provided with a pin set, the pin set is connected with the transmission line, and the first lens module is arranged in the structural frame. Optical signal transmission is realized between the optical fiber group and the photoelectric conversion chip through the lens module, and part of the thickness of the first lens module is embedded into the through groove of the PCB, so that the overall thickness of the optical module is reduced. The overall thickness of the optical module is equal to the sum of the thicknesses of the structural frame,the PCB and the optical fiber carrier, an electric signal transmitted from an interface in the PCB is transmitted to the driving chip through the transmission line, photoelectric conversion is achieved through the photoelectric conversion chip, an optical signal sequentially passes through the first lens module and the second lens module, and the transmission optical path is short; low-loss transmission of signals can be achieved, the upper surface or the lower surface of the structure can make contact with the shell directly or through heat-conducting glue, and high-efficiency heat dissipation is facilitated.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an optical module for signal transmission. Background technique [0002] The optical transceiver integrated module, referred to as optical module or optical fiber module, is an important part of the optical fiber communication system. It is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. For optical signals, the receiving end converts the optical signal into an electrical signal. Simply put, the function of the optical module is to convert the electrical signal into an optical signal at the transmitting end. After transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal. The packaging method and signal transmission method of optical modules determine the size and signal quality of the entire optical module. ...
