In contrast to other reviews I figured I had to add that this adapter does work well with Copper Twinaxial cables, Cisco included. I have one of these adapters in a storage server I built using iSCSI as the protocol. This adapter hooked up seamlessly with a Cisco Twinaxial cable to a Cisco 2960-S (certain models of the 2960-S have 2x 10-Gigabit SFP+ modules.) that particular server now acts as a SAN in my network, jumbo frames fully supported and doesn't show the slightest sign of slowing. The Cisco Twinaxial cable combined with this adapter gives the benefit of significantly lower latency than its Cat-6 ethernet relative and provides outstanding results in my setup.
