Solid build quality, worked straight away with the FS switch with no errors. On my list to buy again when more is needed.

So far so good at present time. We just finished/completed all the configurations and then connecting the Nutanix server to FS fiber switch, and to Cisco Core switch - all works fine.
The SFP+ and X2 10GB transceivers are all working good as well with no compatibility issues. Configuring the FS switch is not so difficult to learn, understand and to follow.

When you have compatibility issues, the first choice could be FS.COM. These guys can make a perfect combination between different switches. As a personal shopping, I just want to get one unit X2 module can work with my Cisco & Extreme switches. I found many vendors and they cannot do that, at that time, my friends recommended FS to me and firmly said FS can help me. After trying, It’s amazing that they could code the module with high-end code which could fully compatible with my devices. It’s really shocked me, I’ll spread this news to everyone.

I have cooperated with FS.COM for a few years and have never been disappointed with their products. Their professional Technical Team has finished the OTN solution within one day to avoid any delay of my projects. No complaints-thanks for the great service and technical support.

Will be impossible to find a better company to work with, this guys can make a perfect combination between different switch. Recently, I just want to get a X2 module to work with my Cisco & Extreme switch, it’s an exciting news that FS.COM could customized the module with high-end code for me. Excellent!!!

That's a secret! I purchased the Cisco Compatible 10G X2 SR transceivers from FS.COM, they are working well with my equipment(Cisco 4500X switch). It's so great! I will purchase again. ^^
