This 25G WDM converter is just what I want. I really got it right this time. I need a long-haul 25G-100G connection. Their solution is just suitable to solve my problem. The whole signal transmission is basically not affected by the distance. I bought their modules and fibers too. Networking is very convenient with FS.

Got two pieces of 25G WDM converter and two managed chassis for two-site construction. Nice quality and I will continue to buy them as long as their pricing stays competitive.

Two 25G OEOs are used to convert the 100G optical signal into 4*25G DWDM wavelengths. A 40-CH DWDM passive MUX/DEMUX works sufficiently with 25G DWDM SFP28 to transmit 25G over individual DWDM channels on our MUX/DEMUX.

We took FS team’s advice to do the 100G connection: 100G - 25G AOC - 25G OEO - 4x 25G DWDM modules - DWDM MUX DEMUX. We bought the OEO and matched modules, and all the products worked as advertised.

Really impressed by FS online support. Got the info about our demands, they recommended the 25G OEO for our 50km transmission at once. Installed the item in our new office, worked well with our devices.

I bought this 25G transponder for about a month. Yesterday, there was a need to add this transponder in my 25g network, but I forgot where I had put the CD with monitor online software that I had received from FS. I came to their website for help. I found this software is provided on its product page. That was really thoughtful. I could download the file I need directly.
