Fixing structure for fixing optical fiber adapter of optical module, and optical module

Abstract

The invention relates to the technical field of optical communication, and provides a fixing structure for fixing an optical fiber adapter of an optical module. The fixing structure comprises a groove and a fixing piece capable of pressing the optical fiber adapter in the groove, the fixing piece comprises a screw, and the screw fixes the optical fiber adapter in the groove. The invention further provides the optical module. The optical module comprises the optical fiber adapter and the fixing structure used for fixing the optical fiber adapter of the optical module. The structure is simple, the optical fiber adapter can be firmly fixed only by screwing down the screw, and the process is simple and convenient compared with a traditional structure; the positioning precision is high by adopting the screw to position the optical fiber adapter, and the optical fiber adapter is firmly and tightly attached to the groove to be fixed after the screw is screwed down; and a pressing plate is used for fixing, and the pressing plate is rigidly connected with the optical fiber adapter, so that the reliability is high.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to a fixing structure for fixing an optical module fiber optic adapter and an optical module. Background technique [0002] With the development of the optical communication industry, the data traffic to be transmitted is increasing, and the demand for optical modules is also increasing. At the same time, higher requirements are put forward for the control of the cost of optical modules. In order to further reduce costs, the optical engine packaging mode of directly connecting optical devices to PCB boards (COB) has also achieved rapid development in the past ten years. The optical module includes a transmitting part (TOSA) that converts electricity into light and a receiving part (ROSA) that converts light into electricity. The fixing of the optical fiber adapter in the transmitting part is a technical difficulty. How to fix the optical fiber adapter directly affects ...

Problems solved by technology

[0006] Fiber optic adapters need to use clamps to assist in fixing, and the process is relatively complicated

If you do not use clamps to assist in fixing, the optical fiber adapter will move when the glue is curing, causing the optical path to shift, which will lead to the failure of coupling light into the optical fiber in the subsequent process; the positioning accuracy of the optical fiber adapter using clamps depends on the assembly accuracy of the clamp. Once the clamp is assembled, it will not be correct. Fortunately, the optical fiber adapter will also move out of position, which will lead to the failure of the subsequent process to couple the light into the optical fiber; the use of glue to fix the adapter itself also has reliability risks. After long-term use of the optical module, the glue may loosen and cause optical path deviation. shift, resulting in the failure of the optical module; there is also a certain risk of damaging the pigtail of the fiber optic adapter when using a clamp to fix the fiber optic adapter, thereby reducing the yield rate of the product license
