The modules are working fantastic, as expected.

We ordered two for our 28km transmission, and hoped to receive them as soon as possible. The sales kindly arranged the shipping quickly and informed us of the logistics. The products arrived faster than we expected and ran well on our Cisco switches.

With the DOM feature, it is easy for us to troubleshoot the failure of the link, which offers us a lot of convenience. Nice feature.

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.

Hello, they worked well. We just ordered another 83 of them. Thank you

I've come to expect very quality products from FS and these deliver on those expectations once again.
