We are trying to go from an HP Procurve gigabit switch to an Extreme Summit switch but are not getting connectivity.  We used to go from a Unix box to the same fiber port on the Extreme Summit switch but have gotten a gbic module for the HP Procurve to try to connect those but it does not work.  The gbic and the fiber cable are both good.  Is there different gbics to go from switch to swith as opposed to going from switch to server?  If so what do I need?

Make sure both GBICs or Fiber ports are of the same type - for instance both SX or both LX.  There are other types, so you want to make sure you're using the same on both ends.

A quick and dirty check for the fiber is to shine a flashlight through one end and eyeball the other.  Do NOT look directly into a fiber connected to a fiber transceiver.

Make sure that you cross over the fiber when you connect from switch to switch, just like you would with copper pairs.

The one GBIC had gone bad somehow.  We replaced it and all was well.  Thanks for the answers!

Well, you need to award points somehow. You said the GBIC was good and we all provided information to answer your question.
