The SPA-1x10GE-L-V2 supports XFP, not SFP.

There is no need to use attenuators for 10GBASE-LR even if you run it over 
a 1 meter cable. Also, I would be very surprised if cisco didn't support 
SR in that module, where did you get that information?

For 10GE on 12k, I'd say the SIP-601 + SPA1x10GE-L-V2 is the best way to 
go.
