Features
25G SFP28 Loopback Module for Testing
This low-profile passive SFP28 25G loopback cable features typical insertion loss (attenuation) characteristics of a mere 0dB, consuming no more than 0.0 Watts of power during the testing process.
Power Consumption
0W
Attenuation
0dB
Max Data Rate
28Gbps
Make Port Testing Easier and More Efficient
Compared with traditional loopback testing where modules are connected to jumpers, loopback modules are simpler and more efficient in port testing, allowing you to check port operating status by simply plugging in the switch.
No Compatibility Restrictions
The loopback transceiver is compatible with all SFP28 ports and can be widely used in switch NIC router and other equipment testing, R&D validation, and field analysis.
