To be honestly, I don’t know what to find the high quality with cost-effective transceivers, my friend recommended me to purchase them on FS.COM. He said their purchase department always purchase here and the items work perfectly with his server, most importantly, the price is very low. So I want to have a try, the items arrived on time. I have tested the items last night, they worked straight away with my Cisco switches, very fast connectivity. Just what I need!

It takes nearly 2 weeks for me to receive my Cisco C19 XFP, because no stocks here. It a little delayed my project, I expected to carry on as early as we can before. Fortunately, they work great. I will remember to buy in advance, and to leave more time for my scheduled cases.

This platform gives the impression that is very professional. I used it on the switch for several days, the performance is very stable, not very hot, quite good and reliable.

I bought this items for my Cisco switch. They are packaged well and nothing is damaged. I inserted the transceiver and cable into the switch smoothly with the help of its instructions. Everything started working immediately. No compatibility problems so far. In fact, I was told that their modules were fully tested on the brand switch before shipment. It seems true now.

My friend asked me to get this for him. He came back to me and said that this is a great product with great price. It works perfectly with his server. He has asked me to share the feedback here. As an IT, he would recommend this to people who is looking for a transceiver.

My switch is Cisco 3650 series, and the Ciso website mentioned the 10G DWDM optics can work on the switch, but not mention the distance. Actually, I really worried it can't work at first, the sales told me I can place a test order for testing, if not work, they will do refund for me. So I purchase 2pcs for test, and it works great. So I will purchase a lot for my project this time, hope they work well, too, thanks

I was attracted by a passage of FS.COM on the website, later I found products in your website all look good. Since quality assurance is five years which really makes me rest assured so I just placed the order without hesitation. A lot of spot inventory is especial to my satisfaction, but also the performance of the transceiver is stable, high praise.

I have used quite a few of these in my system, excellent product. The only failure was when operating in extreme low temperature beyond the specs, and it started working again when warmed up.

Before I getting to know FS.COM, I also searched this transceiver somewhere else, unfortunately, there is no inventory. Then I found FS.COM, also no stock but they promised to produce it in 4-5 business days, much shorter than others, so I placed the order. And they just made it, I received the transceivers in time, no delay for my project. Appreciate!

I have to say the price is really attractive! This is not the first time I purchase here.
What surprise me is the lead time, they support same day shipment while other vendors always let me wait for nearly one week.
This time, I tried to ask them to design a WDM solution for me, still waiting for their update.
