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 QSFP+ ports and can be widely used in switch NIC router and other equipment testing, R&D validation, and field analysis.

Very powerful loopback modules. These modules came in time with a secure package. I have used them in testing 40G QSFP ports on my cisco switches and I admit it is a great way to test QSFP connectivity on cisco switches. I’m quite satisfied with them.
