Optical module

Abstract

The invention discloses an optical module. The optical module comprises an upper shell, a lower shell, a circuit board, a lens assembly and a clamping jaw assembly, and the lens assembly is arranged at the end, close to an optical port of the optical module, of the circuit board; the clamping jaw assembly is arranged at the optical port of the optical module, one end of the clamping jaw assembly is directly 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 connected with the clamping jaw, a first limiting piece is arranged on the lower shell, a second limiting piece is arranged on the clamping jaw, and the first limiting piece is embedded in the second limiting piece; and a first positioning piece is arranged in the first limiting piece, a second positioning piece is arranged on the side face, provided with the second limiting piece, of the clamping jaw, and the second positioning piece is inserted into the first positioning piece. According to the optical module, the lens assembly is arranged at the end, close to the optical port of the optical module, of the circuit board, direct connection between the external optical fiber and the lens assembly is achieved through the clamping jaw assembly fixed to the shells, an optical fiberribbon is not needed, space is saved to a certain degree, 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
