I do enjoy browsing the FS.com website! Lots of ideas come to mind. If I have any questions, I will be in touch.

So far, the modules are performing as we expected and meet our needs. We haven’t encountered any challenges with the modules.

The package arrived on Friday as expected and the item functions perfectly. I have nothing but positive things to say. The item was priced well, the ordering process was easy, and the shipping was fast. I will definitely use FS in the future if I need other fiber modules or networking devices like this.

I was recommended by one friend to try modules here when I searched for 10G Cisco compatible CWDM module solutions online. I tried them on many Cisco switches and all performed well. It seems that these modules will last for a long time. I’ll definitely buy some again.

The AM helped me to check whether the modules were compatible with Cisco Nexus 3000 switches. After receiving the affirmative answer, we bought two. Plugged them on the switches, the LED turned on, and zero packets dropped.

We worked in Philadelphia. I'm grateful that FS has a warehouse in Delaware, and the AM shipped the CWDM modules from the warehouse. They arrived without any damages. We did a test on our switch, the modules worked as advertised.

Used this 10G CWDM SFP+ module on our WDM converter to connect with the CWDM Mux we had. No issue occurred. And the price was relatively lower than other vendors we found before.

We have a Cisco C9500-24Y4C switch, and we were searching for the Cisco compatible transceivers with wavelengths of 1550 and 1570 for 8G fiber channel transmission. These modules should be installed in CWDM MUX. We were not sure if this 10G CWDM module works or not so I checked with the AM and the FS technical group gave me advice. I bought these modules on the recommendation. This works very well, and I’ d like to say it is just the solution I needed.

We had two CWDM devices with 1470nm and 1490nm, the two CWDM mux demux were single fiber. We needed a pair of 10G CWDM modules. So we asked FS for advice. My account manager gave me really useful recommendations. We picked this CWDM module and confirmed it is the right device that we needed. These modules did a very good job, without any issues. I would buy more from FS if I need.

These have worked well for us so far and FS.COM custom coded them for us so they would work in our 3560X Switches.
