This is a fantastic way to utilize DWDM. It's just as intuitive as a standard patch bay, just plug into the right channel on both ends. This uses the standard duplex positions, so there's no second-guessing which direction your fibers should plug in.

I've bought this product and had it running in my system for about 5 months. Here is what I can gather about it: working great, helping to realize efficient 30km transmission, saving us a great bunch of fibers, ideal for our DWDM network deployment. All in all, I would recommend FS for those who are trying to find the optimal OTN solution provider. Will update if I have any issues.

First off, let me say that this is a great product that is well built and works perfectly. For that, it deserved 5 stars. Specifically, solid product, low loss, remarkable manageability, fiber-saving & space-saving, reasonable price, on-time delivery, and nice services. Fabulous!

Bought this product for deploying a DWDM network. The insertion loss is low indeed. Very efficient transmission and saved us a great bunch of fibers. We'd like to give five stars.

We turned to FS for a basic point to point DWDM build using the 40ch mux/demux. They quickly replied with a solution to transmit business by the way of dual-fiber bi-directional, which is said to achieve 400G business transmission. Finally got 80 10G DWDM SFP+ and 2 40 Channels C21-C60 dual fiber DWDM Mux Demux, deployed in accordance with the instruction. Now things go well. We’ll come back when looking for advice on what to order.

I purchased these for accomdating several FMU plug-in modules. This is not my first purchase of this case. Nothing special to mention about it. It is just good quality at a fairly price. For a value 1U case, it does its job. The screws that came with are solid and abundant. I only load them with FS self-designed plug-in modules which all fit in it well. Be sure you pay attention to the product description if you try to insert other components.

Use the mux to run multiple 10G DWDM waves in our telecom room. We also bought some compatible Cisco 10G modules, then connected the mux to our Cisco switch. Packets run smoothly.

We are going to buy some DWDM products for our metro network project, including DWDM mux/demux, OADM, transceivers(which must be Fibre Channel DWDM SFP+), and some other components like switches, fiber cables, chassis, etc. This is a huge and essential project, so we want to make sure everything about the product and quantity will be right. We asked for help from the FS tech group. They gave me very detailed and professional suggestions. Any question they would be patient to explain. They also made a solution and clear product lists. They advised me to choose this regular 19” 40CH mux/demux with insertion loss lower than 5dB. And it can still work even when power is off. With O16/G26 EDFA, OADM, this long-distance DWDM transmission network would work well. You guys did a great job. Save us budget. We are considering to come back again in the future.

We considered buying a DWDM mux and wondered if the 1310nm port could use with our 40G transceiver. On the website a Q&A answered that the 1310nm Port Pass Band Width is 1260nm-1360nm. Then we bought this mux with no more questions. Product is easy to use as well.
