CWDM technology provides the flexibility to increase capacity of existing fiber infrastructure by enabling multiple channels/wavelengths over the same fiber cabling. Each channel carries data independently from each other, allowing network designers to transport different data rates. It's protocol and rate transparent supporting such applications as 1G/10G Ethernet, SDH/SONET and 8/4/2/1G Fiber Channel across the same fiber link.
In addition, FS professional technical team always try their best to meet customer's network expectations by designing the most quality and cost-effective optical transport solutions as possible.

Application of Different Transmission Rates in Mux/Demux
Mux can enable different rates of data to be transmitted simultaneously without disturbing other transmissions. Ensure consistency rate of multiplexing and demultiplexing.
The monitor port on the CWDM MUX uses an optical splitter to monitor the power of multiplexed signal. The split ratio can be customized and the default split ratio is 1%. The port cannot serve as a live fiber test port. By FS on 10/24/2018
Thanks for your question. This item belongs to passsive product, which is only selective for wavelengths. It will not affect the transmission of jumbo frames as long as the wavelengths match. For further question, welcome to contact with Sales@fs.com freely. By FS on 08/08/2018
Only the monitor port is available, the expansion and 1310nm port can not be added since 18CH CWDM Mux Dwmux covers the full channels of CWDM Mux Demux, the expansion port is not required. And if the Mux Demux has 1310nm special port, it cannot use the wavelength of 1270-1370nm, so the 1310nm port can't be added on 18CH CWDM Mux Demux. By FS on 01/30/2018
Yes, since 1310 port can transport the adjacent +/-40nm wavelengths signals, you can use 1270nm-TX/1330nm-RX & 1330nm-RX/1270nm-TX BIDI module on 1310nm port of CWDM MUX DEMUX. By FS on 01/30/2018
Yes, if 1550nm port connects 1550nm optical transceiver, please skip these five wavelengths (1510nm, 1530nm, 1550nm, 1570nm and 1590nm) when choose the channels of CWDM MUX DEMUX. In the same way for 1310nm, please skip 1270nm, 1290nm, 1310nm, 1330nm and 1350nm. By FS on 01/30/2018
Yes, we can customize your Mux perfectly tailored to your specific needs. Any wavelength, any connector, any housing and any special ports can be achieved. By FS on 08/11/2017
This could be achieved by connecting the 1530nm or 1550nm CWDM channel to the line port of DWDM Mux Demux. CWDM 1530nm matches to narrowband C52-C61 of DWDM, CWDM 1550nm matches to narrowband C30-C37 of DWDM. By FS on 06/08/2017
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.
We had a new dark fiber between our controlling room and streaming office with 3km apart. We planed to use CWDM to break the dark fiber into multiple waves. We once happened to see FS OTN cases online, and thought they might offer some help for our project. Exactly, they did. We talked with the AM and told him our demands. The man confirmed the details with us, and always answered our connecting questions in patience. We were grateful that the final solution 18CH CWDM MUX system met all needs. We could use it to deliver our 12CH businesses at 10Gbps, and the other 6 could be reserved for expansion. Except for the 18CH MUX, we also bought the compatible modules and fibers recommended by the AM. Everything is great, will come again.
The final solution meets our demands for CWDM and monitoring. We are satisfied.
The deal started with a talk with our account manager. We needed to connect two data centers located at two different places, and there was already a pair of G.652D Dark Fiber of 2 kilometers long between them. We wanted to break them into CWDM wavelengths thus allowing future expansion, but the switches in two data centers adopted 10G transceivers of normal wavelengths only. At first we thought it would be complicated to solve these problems, however, FS team made out the plan within a day. They recommended us using OEO to convert 10G SR signals at the two data centers into CWDM wavelengths, then they can be transmitted by the CWDM transceivers and 16CH CWDM muxes. Their FMT system could monitor the FS products as well as some of our devices. A good system for convenient monitoring!
Our original need was to deliver and monitor several 10G and 1G signals, and a 3G video signal. We talked with FS about our needs and they suggested using 16ch CWDM solution. The solution worked like a charm, and there are some channels left for future expansion.
We had been doing lots of research on FS products, and wondered whether the 18 channels CWDM mux could fit our transmission less than 2km. We contacted the AM. The guy first asked our networking environment and optical loss requirement. Then he assured us that the mux could fit our demands, and recommended the 40km 10G CWDM modules and related fiber optic attenuators. Thus, our RX power of the transceiver can be limited in the range of -8~-13dbm. We quickly got our items from UPS. They were protected in solid packages. Just installed the ears on the two sides of the mux, we could easily put it on our network rack. We have run it for a time, no bad or missed connections.
I had bought two FMU-C182761M in FS for my site to site dark fiber network before, the products work well. This time I planned to insert an add/drop module in the middle of the network. According to my current network, my account manager suggested me to use the dual fiber cwdm oadm matching with this rack chassis. Having used a while, this fmu chassis is indeed useful for saving rack space and managing modules.
About two weeks ago, we were preparing our purchase list including some SFP modules, fiber jumpers, panels, and CWDM MUX/DEMUXes. We'd love to buy all of the components from FS, but I was still uncertain whether the 9ch Single-fiber CWDM MUX/DEMUXes would fit our demands. So I turned to FS's account manager for help. The AM provided me with a solution of deploying 9ch and 2ch CWDM MUX/DEMUXes based on our case. The maximum link loss was within the range of acceptance. Their detailed product list covered EVERY item description and some remarks for my reference, which impressed me indeed.
Bought the mux and the related FMU mounting chassis. FS guys delivered the products quickly. We took the items out from the good packing. The physical construction of the mux was as solid as we expected. We had done two projects with FS guys, and would recommend to anyone.
We need a 14km connection between two sites. We wanted to adopt a WDM solution, DWDM seems not cost-effective due to our tight budget. After discussing, FS's technical team recommended us with another CWDM solution including the following components: 9ch CWDM MUX/DEMUXes (1270-1590 on side A and 1290-1610 on side B), customized OEO, FMU Chassis, and some matched modules and cables. The solution they provided was rather exhaustive, which solved our problems effectively and meet our 14km-transmission requirements. Thanks for your tech support again!
