This isn't probably isn't a Linux question, it's really a hardware issue 
but please answer anyway.

I have a couple of Intel E10G42BTDA Dual SFP+ 10G NICs in a pair of 
Scientific Linux 6.1 systems. They work fine when I connect them together 
with passive copper cables but they don't get signal detect when I connect 
them with fiber. I'm using Finisar transceivers with 2M fiber LC-LC 
cables. I've been able to reliably send data through the fiber cables from 
an FPGA card that I'm working on so I know the cables are OK. I've tried 
reversing the cable connections and that doesn't help. 

Is there something that has to be configured to make them work with fiber?
