Embodiment Construction

[0024] As the optical fiber transmission rate increases, the number of optical fibers continues to increase. In order to accommodate a large number of optical fibers and realize photoelectric conversion, the volume of the lens assembly and the optical fiber holder continues to increase, and the overall volume of the optical module continues to increase. However, multi-fiber and large-volume optical modules cannot meet the requirements of package integration and miniaturization, and will increase the manufacturing cost of the optical module.

[0025] In view of the above problems, the present application provides an optical module to reduce the volume of the optical module and reduce the manufacturing cost of the optical module while realizing multi-channel simultaneous transmission. The core idea of ​​the optical module provided by this application is: the first driver chip, the first photoelectric chip, the second photoelectric chip and the second driver chip are sequentially...

Abstract

The invention provides an optical module. The optical module includes a circuit board, a first driving chip, a first optoelectronic chip, a second optoelectronic chip, a second driving core and a lensassembly. The upper surface of the lens assembly is provided with a first groove and a second groove. The bottom surface of the first groove forms a reflecting surface; and the side surface of the second groove is provided with a first lens array and a second lens array which are arranged up and down. The first lens array and the second lens array which are arranged on the side wall of the secondgroove can increase an optical transmission channel, reduce the volume of the optical module, and reduce the manufacturing cost of the optical module. Since the light emitted or received by the firstoptoelectronic chip passes through the reflecting surface and the first lens array, the light emitted or received by the second optoelectronic chip passes through the reflecting surface and the second lens array, so that the reflecting surface can simultaneously reflect two sets of light to form two optical paths arranged up and down, and then the multi-channel simultaneous transmission of lightis achieved on the basis of increasing the optical transmission channel.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an optical module. Background technique [0002] Active Optical Cables (AOC) are communication cables that use external energy to achieve photoelectric conversion during the communication process. Generally, an AOC includes an optical fiber and optical modules located at both ends of the optical fiber, and photoelectric conversion can be realized through the connection between the optical fiber and the optical module. [0003] The optical module is a component that realizes photoelectric conversion in the AOC, that is, the transmitting end converts the electrical signal into an optical signal and transmits it through an optical fiber; the receiving end converts the received optical signal into an electrical signal. Generally, the optical module includes an upper housing 01, a lower housing 02, and a circuit board 03, a chip 04, a lens assembly 05, and an optical fiber hol...
