Optical module

Abstract

The invention discloses an optical module. The optical module comprises a circuit board, a light emitting chip, a light receiving chip, a lens assembly and a clamping jaw assembly, the lens assembly is arranged at the end, close to an optical port of the optical module, of the circuit board and covers the light emitting chip and the light receiving chip, one end of the clamping jaw assembly is connected with the lens assembly, and the other end of the clamping jaw assembly is connected with an external optical fiber; the clamping jaw assembly comprises a clamping jaw and a shielding plate, a first positioning piece is arranged on the clamping jaw, a second positioning piece and a third positioning piece are correspondingly arranged on the shielding plate and the lens assembly respectively,and the first positioning piece penetrates through the second positioning piece and is inserted into the third positioning piece; and the lens assembly comprises a lens assembly body and a lens assembly connecting part which are connected with each other, a light through groove is formed in the lens assembly connecting part, a light through hole is formed in the shielding plate, and light path connection of the lens assembly and the clamping jaw assembly is achieved through the light through hole and the light through groove. According to the optical module provided by the invention, transmission of internal optical signals does not need an optical fiber ribbon, so that space is saved to a certain extent, and further development of the optical module is facilitated.

Description

technical field [0001] The present application relates to the technical field of optical fiber communication, and in particular to an optical module. Background technique [0002] In cloud computing, mobile Internet, video and other new business and application modes, optical communication technology will be used, and in optical communication, optical module is a tool to realize mutual conversion of photoelectric signals, and is one of the key components in optical communication equipment . The optical module is mainly used for photoelectric and electro-optical conversion. Its transmitting end converts electrical signals into optical signals and transmits them through optical fibers, and its receiving end converts received optical signals into electrical signals. [0003] In some optical modules with a COB (Chip On Board) package structure, an optical fiber ribbon and claws are arranged in the optical module to realize the transmission and reception of optical signals in th...

Problems solved by technology

However, when the optical fiber ribbon is used in the optical module to transmit optical signals, it is necessary to reserve corresponding installation controls for the installation of the optical fiber ribbon, and at the same time, it is necessary to bear the reliability risk caused by the damage of the optical fiber ribbon, and to set the optical fiber ribbon to increase the optical module accordingly. manufacturing cost issue
