Abstract

The invention discloses an optical transceiver module SFP tester, which comprises a testing circuit board, a programmable power supply, an oscilloscope, an error rate analyzer, modular optical switches S1 and S2, and a PC host. An optical transceiver module SFP is arranged on the testing circuit board; the optical switch S1 is connected with the circuit board; and the testing circuit board is connected with the programmable power supply, the error rate analyzer and the PC host. One end of the oscilloscope is connected with the circuit board through the modular optical switch S2; and the other end of the oscilloscope is respectively connected with the error rate analyzer and the PC host. The optical transceiver module SFP tester can test the photoelectric properties of eight paths of optical transceiver module SFP, greatly saves the testing time, and saves the testing equipment. Therefore, the optical transceiver module SFP tester reduces the testing cost and is easy for realizing mass production.

Description

technical field [0001] The invention relates to an optical transceiver module SFP testing device, in particular to an instrument capable of testing a plurality of optical transceiver module SFPs. Background technique [0002] The optical transceiver module SFP is an interface device for photoelectric signal conversion, which has the characteristics of miniaturization, standardization, hot-swappable and self-diagnosis. The technical implementation of the optical transceiver module SFP is relatively difficult, and complex signal integrity, reliability, stability, and electromagnetic interference must be considered. Therefore, multiple tests and evaluations of the optical transceiver module SFP are required before leaving the factory. At present, the tester used in the R&D and production process of the optical transceiver module SFP can only test one optical transceiver module SFP at a time, the test efficiency is low, and it is not easy to mass-produce.
