Description

technical field [0001] The present invention relates to a detection device and method for module timing parameters, in particular to a detection device and method for accurately and automatically detecting timing parameters of SFP (Small Form-factor Pluggable transceiver, small package pluggable transceiver) modules. Detection method. Background technique [0002] The SFP module is a small hot-swappable optical transceiver module, which is installed in the SFP slot of the Gigabit Ethernet module to provide gigabit connections with other switches and servers. The timing parameters of the SFP module are within a reasonable range The size plays a crucial role in reducing the occurrence of faults in the optical link, so it is also particularly important for the timing parameter detection of the SFP module. At the same time, the MSA (MultiSource Agreement, multi-source agreement) protocol ensures the interoperability of optical device products from different suppliers. The MSA p...

Problems solved by technology

At present, the entire system for testing the timing parameters of the SFP module is relatively complicated and requires manual operation. Sometimes two people are required to cooperate to complete the timing test. There are defects in the test that are not standardized and are easy to introduce errors.
