2. Transceiver Identification

The SFP-GE-CWDM-1530-32DB-I-F10 was inserted into Huawei S5700-52X-LI-48CS-AC switch and connected with fiber jumpers. The switch can fully identify the transceiver information including model, manufacturer, connector type, wavelength and transmission distance. Meanwhile, DOM data can be read normally with all parameters within the threshold range and no alarm generated.
