    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

    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.

  3. 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.
