If you want to do 1g on QFX you need to use an SFP transceiver. If you want to do 10g you need an SFP+ transceiver. This is specific to the QFX platform you are using... Check here for the QFX5100, make sure yours is a match..

I'll make more tests, but I had trouble trying to connect 1G/100M on QFX5100-48T with old devices.
