single mode fiber light detection

So, i've used my camera to look for light when i troubleshoot SM fiber. Im trying to bring up a circuit, and im having a hard time bringing up L1. I see light via my camera on my Xenpak 10 gig optic, but i don't see light on the fiber drop. The colo guys can test it with a fluke and see signal, but i can't see it via my camera, even though i can see the Fiber module on my 6500. Any ideas as to what could cause SM to SM fiber not to come up? My TX and RX are correct and i've flipped them just to verify.
