Optical module

Abstract

The invention provides an optical module, and the optical module is installed in a switcher cage in a pluggable manner. The optical module comprises a substrate, a handle, a locking block and a cover plate, wherein the handle, the locking block and the cover plate are disposed on the substrate. The handle comprises a cross beam and cantilevers which are bent at two ends of the cross beam. The cantilevers are rotatingly connected to two sides of the substrate, and the edges of the cantilevers are shaped like flanges, and abut against the bottom surface of the locking block, so as to enable the locking block to rotate under the drive of the cantilevers. An elastic piece extending on the surface of the cover plate is pressed on the locking block, and is jacked through the rotation of the locking block to generate elastic deformation, so as to enable the locking block to reset under the action of the elastic piece when the optical module is unlocked in the switcher cage. The optical module provided by the invention can achieve hook resetting through the elastic piece, is simple in structure, is convenient for assembly and disassembly and maintenance, effectively improves the working reliability of an unlocking resetting part, and alleviates the assembly workload of a production line.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to an optical module. Background technique [0002] The optical module is the core device that transmits the optical signal through the optical fiber in the optical fiber network. Among them, the SFP (Small Form-Factor Pluggable, miniaturized and hot-pluggable) optical module realizes the transmission and reception of optical signals by cooperating with the SFP interface in the switch cage. Because the SFP optical module is hot-pluggable, it can be When the power supply of the optical fiber equipment is cut off, the connection or disconnection of the SFP optical module and the switch cage can realize the timely update of the optical fiber network system, and avoid the impact on the use of online users. Therefore, the SFP optical module is widely used in the field of optical communication technology. widely used within. [0003] When the optical module is inst...

Problems solved by technology

[0004] In the existing products, the hook in the optical module is reset by a spring component, but when the optical module is inserted and pulled out in the switch cage for many times, the spring is easy to fall off due to its unreliable fixation; moreover, As a vulnerable part, the spring has a low service life. During actual use, the spring is prone to jamming or breaking

The above reasons will cause the spring to fail to work, and then cannot provide a reset action for the hook, making the locking or unlocking action of the optical module in the switch cage invalid, reducing the reliability of the optical module during the insertion and removal process. Separate parts will also increase the assembly workload of the optical module
