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
