Hello - I am using 1000B-X GBIC Fiber module from two different vendor equipments. When I connect the Fiber links I see that the link does not come up. Whereas if I use 1000BASE-X GBIC Fiber modules from same equipment vendors, the link comes up.
Could someone explain this behaviour ? Is it to do with some specific vendor implementation that only links up with its own implementation?

Do a show interface after you've stuck the gbics in. Does it report the proper (and same) media type on both ends? Some third party brands are not properly recognized in some combinations of Cisco switches and IOS. You might also be mixing SX and LX modules.

even worse. Some vendors only allow there own GBIC/SFP.

could be an attenuation problem?
In theory not unless he's using ZX modules. I'd think he would know that given the huge price tag on those. For the Cisco gbics, the SX and LX modules transmit power is not above the max receive level.
