This product is exactly what we were looking for and came as expected. Done a lot of testing with a very helpful tech support, it works great with my switch.

All the stuff we got from FS all is great so far! I will continue to purchase in the future.

Second time ordering from FS. The services provided by them had always not let me down. They always responded to you in a timely manner with great enthusiasm. The package was well-packed with no damages. The modules could work well on my Cisco switches. Anyway, I was very content with this purchase.

It was a great online shopping experience at FS. Not a lot to say about the item that worked flawlessly. Hadn’t any problems with the SFP+ loopback modules. Provided me an effective way of testing the SFP+ port in the host system by looping back the electrical signal (optics are excluded). Would buy it again.

We tested the loopback module and it works well in my lab.
