The single-fiber SFP transceiver is shamefully expensive, it is 
basically a 4-way WDM module. There is an effort in the 10G committees 
to spec the quad-fiber cable that is used for many other things. It is 
much less expensive because there is no need for WDM, and it keeps the 
good properties of fiber cables.

The last time I asked, the public price was roughly (it of course 
depends on the number of nodes) $800 per port (all in) for 2G/Fiber, 
$1200 per port for 10G/Copper and $1600 per port for 10G/Fiber. For the 
IT market, the 10G/Copper NIC with the Ethernet-mode firmware was $800.
