Features
100G QSFP28 Loopback Module for Testing
This low-profile passive QSFP28 100G 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
112Gbps
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.

Thanks for reaching out, FS.com has had excellent service since we opened our account – I plan to continue ordering cables, jumpers and modules when needed.
Thanks for the information on the switches, I will keep that in mind for when we need to order network equipment in the future.
