Nice service.

Great support!

Got these loopback modules for our transceiver board-level test. These modules worked great on our switches and the test results had no problems. These modules provided us a cost-effective method for our SFP28 port testing. Quite satisfied!

Personal Experience:
Just need several testing modules for our SFP28 connectivity tests. FS is always our first & best choice. That's it.

Pros:
Compact design.
Cisco Compatible.
Easy to install.
Worked on our switch.

Recommend:
Yes.
