There are daughter cards for SFP+ connectors for the ROACH2 These allow either copper or fiber. You can get transcievers for either single mode or multi-mode, or copper cables with the cables and connectors all made up. Google around for sfp+ and you will find lots of possibilities. The daughter cards each contain 4 SFP+ connectors. The card for the PC is likewise SFP+ enabled. We use mellanox, solar flare, and Myricom NICs with good luck on Red Hat. Likewise new switches are SFP+ enabled. I wouldn't fool around with cx-4 connectors unless you have a boatload of old stuff you have to try to use.
