You've got a 10G link to wire up and the last thing you need is a transceiver on each end plus a CAT6A run that adds latency. The D-Link DEM-CB300S is a single passive SFP+ twinaxial cable, 3 metres long. Plug it into both ends, your 10Gbps link is live. Lower power draw than 10GBASE-T or CX4, no modules to source. Two are on the shelf right now if you need one this week
