We have used them for a project, and they have performed as expected. We are very happy with all the products we receive from FS.

Easiest setup and connection there is.

Believe it or not this mux demux just solved an issue ive been having for months, Ive been dealing with the problem of fiber redundancy on my existing network for months. I no longer have any similar problems on my lines, I get a solid clean connection now every time. there was no setup required. So far I'm super happy with this so far.

I like the steel case that shields the unit better than one in a plastic case. So far I have not needed to contact tech support.

The expansion port is very easy to use. I connected it with my spare 8 channel mux to achieve a total of 16 channel data transmission over two fibers.

This small size perfectly solves the problem of large space occupation. Thanks to our account manager, he helped us to optimize our solution. We followed and found the system work smoothly till now. Their advice and support really saved us a lot of time.
