62.5u or 50u Fiber connections

Currently we are using 62.5u fiber between the core switch and the uplinks from our access switches.

If we change from 62.5 to 50 do we have to replace the GBICs and 1000base SX SPFs? I realize I'll need new patch cables but not sure on the fiber transceivers.

Reason I'm asking is we've tasked our wire installation contractor to rum more fiber strands between two bldgs., and he is suggesting that we go with the 50u size.

You do not need new GBICs/SFPs. Also, I have run 10 gig connections over 50u riser fiber with 62.5u patch cables so you may want to try the existing cables before buying new ones. I would definitely recommend going with the 50u per your contractor for future bandwidth growth.
