The modular design is very convenient and can be adapted to the chassis I bought.

This is much more cost-effective than buying a mux separately, and its network management is very easy to use.

I called tech support three times, and they resolved the issues and guided the configuration with docs and demos. Overall, I am impressed with their quick response.

Alles bestens. Gute Preis-Leistung! Gern wieder...

I use it with other equipment for data center interconnection, and the technical support is very good.

We already had 2 existing Dark Fibers which were being used by another part of the business via an FS.com passive mux, we bought Mux this time for our 2 new installed Dark Fiber connections. I would not hesitate to choose FS every time we have a need, nice bit of kit and does the job ok.
