MX Extender? How far apart are the devices. A ZX GBIC will go 70km over single mode fiber, and 100km over dispersion shifted fiber. If you are using an extender and over driving the receive you could be killing the GBIC's. I had a customer use ZX GBIC's over a 15km link and had to add attenuators on the transmit side in order to not over drive the receive.
You'll need to set the interface to nonegotiate dot1q, instead of on.
