Pluggable Transceivers and Direct Attach Cables Supported on QFX5120 Switches

 

QFX5120 switches support SFP, SFP+, SFP28, QSFP+, and QSFP28 transceivers. They also support direct attach cables. You can find the list of transceivers supported on QFX5120 switches and information about those transceivers at the following pages:

Note

We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.

Caution

If you face a problem running a Juniper Networks device that uses a third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC) can help you diagnose the source of the problem. Your JTAC engineer might recommend that you check the third-party optic or cable and potentially replace it with an equivalent Juniper Networks optic or cable that is qualified for the device.

The Gigabit Ethernet transceivers installed in QFX5120 switches support digital optical monitoring (DOM): You can view the diagnostic details for these transceivers by issuing the operational mode CLI command show interfaces diagnostics.
