Why media converter? There are CX4 XFPs as far as I can google...

the cx4 interface is xaui 4x3Gb/s, as is xenpack. xfp is xfi 1 x 10Gb/s
so connecting the two requires a serdes device.

"The XFP-CX4 copper transceiver module provides cost effective and reliable transport of 10 Gigabit Ethernet LAN data over distances of up to 15 meters. Transparently to the user, the module transfers the 10GbE data stream over four full-duplex 3.125 GigaBaud channels over a single parallel copper cable. The product offers the ability to scale bandwidth in 10 Gigabit increments, and directly with the industry standard MDI electrical socket."

I guess this one does that?
