Everything is functioning flawlessly, the shipping was swift and handled professionally. I will certainly consider your services for future orders.

Perfect for resolving large space occupation issues.

We use this for basic networking. Works great, no frills, just mux demux. Small profile means it does not take up much space. Truly plug and play.

All Working as It Should for a Very Reasonable Price. I bought a pair of these to run my network.
They feel rock solid. The housing is substantial and gives me a sense that they can take some abuse. Quality control is solid.
The rack mounting wings go into place easily, and they fit my rack rails just as they should (19 inches).

With a little organization everything is going well (so far). Our WDM devices are deployed and work well.

Fantastic! It's small and lightweight. Low insertion loss just to meet my link loss has a margin.

I had 8 channels of CWDM before, but the network needed to expand I had to buy more channels of mux, I used the expansion port to connect them and it solved the problem perfectly.

I use WDM devices for the first time. It saves a lot of fiber and improves the space utilization of my data center.

All in all, I am very satisfied. It comes in decent packaging, but the product is good. If you have general knowledge, setting is not too difficult, it is easy.

I am looking for mux/demux for my DC interconnect, and I am leaning towards FHD-C84761EM, not only does it supports expanding my existing fiber network capacity, but also supports monitoring. What’s more, the price is very nice and could meet my budget. I think it's my best choice!
