Description

Technical Field

[0001] This utility model relates to the field of optoelectronic technology, specifically to a testing device for optical transceiver components. Background Technology

[0002] The optical transceiver assembly is a core component of the signal detection instrument. During the production process, the optical transceiver assembly needs to undergo various environmental tests, such as vibration and temperature tests, and the test results are monitored in real time during the tests. In the existing technology, when testing the optical transceiver assembly, it is installed in the signal detection instrument to receive signals sent by the entire vehicle, forming a data transmission chain, and finally feeding the test results back to the signal detection instrument.

[0003] Since the optical transceiver is installed in the signal detector, the signal detector needs to be placed on a vibration table or in a temperature chamber during the test, so the test results cannot be monitored in real time. At the same time, during the environmental test, the vehicle is too large to be easily placed in the environmental laboratory. The signal sent by the vehicle needs to travel a long distance to be sent to the signal detector, which will cause signal attenuation and affect the test results. Utility Model Content
