You can use both of them. Look for some possible causes like:

1. GBIC module used is BAD/ Not working. Try using a spare GBIC

2. Cable is not good or wrongly connected. Make sure that you connect the fiber cable correctly and is a good one.

Sometimes the GBIC is not able to negotiate the speed correctly with the other end. Try using the command " speed nonegotiate " under the interface config of the GBIC interface.

HTH,Please rate if it does.
