Optical module test circuit, test device and coding test system

Abstract

The invention provides an optical module test circuit, a test device and a coding test system and belongs to the optical module test filed. The test device comprises a test base, a clamp, a connection module, a test circuit, a push module and a buckle press module. The test base is provided with a switch and a groove; the clamp is provided with a positioning groove; the connection module is fixedly connected with the clamp; the push module is used for pushing an optical module in the positioning groove and fixing the optical module in the test base; the buckle press module is used for pressing a buckle of a sheet metal cover of the optical module positioned in the test base; the connection module is used for connecting the optical module and the test circuit; and the test circuit is connected with the buckle press module and the push module. The beneficial effects are that the functions of automatic positioning and fixation of the optical module, automatic ground-housing short-circuit test, automatic coding and automatic sheet metal cover buckle pressing are realized; the production process is simplified; and loss due to long turnover time among processes is reduced.

Description

technical field [0001] The invention relates to the field of optical module testing, in particular to an optical module testing circuit, a testing device and a coding testing system. Background technique [0002] In the industry, there are three different operations for coding optical modules below 3G, pressing and snapping sheet metal covers, and short-circuiting tests between ground and housing. The coding of the optical module is to insert the optical module into the test socket, and input the serial number of the optical module into the software with a scanning gun; The buckle is pressed; the short circuit test between the ground and the shell is to manually insert the optical module into the test socket for testing. [0003] The prior art has the following deficiencies: [0004] (1) When the above-mentioned fixtures / tools used in the prior art are used, the pressing position is not easy to fix, and it is easy to cause scratches on the sheet metal cover of the optical ...

AI Technical Summary

Problems solved by technology

[0004] (1) When the above-mentioned fixtures / tools used in the prior art are used, the pressing position is not easy to fix, and it is easy to cause scratches on the sheet metal cover of the optical module or the phenomenon that the pressing is not in place

[0005] (2) The turnaround time between the three different processes in the prior art is long, and manual pressing is easy to fatigue the operator and reduce production efficiency

[0006] (3) Since the existing fixture / tool ​​is made of metal or alloy, the relative displacement in contact with the sheet metal cover will easily cause the deformation of the sheet metal cover
