Fiber link issue

Hello,

I have a 3750 as my main switch in the MDF.  I have a Fiber home run running from the MDF to one of my idfs that i would like to utilize as the trunk line.

Currently our fiber lines are running fine going from a 2950 MTRJ port to the SC ,out to the homerun into another SC patch, and then into an MTRJ port on another 2950.

I purchased a sfp (model #GLC-SX-MM) and i cant get a link up on that SFP.  The fiber is multimode, 62.5 and so are the LC to SC patch cables we purchased.  
I even tried hooking up a fiber cable from the 3750 sfp (LC) directly to a spare 2950 MTRJ port and no link there.
I have also switched cables in every possible send/rec combination.  

Thanks,
Joey
