You can find the list of transceivers supported on EX4300-48MP and EX4300-48MP-S switches and information about those transceivers at the Hardware Compatibility Tool page for EX4300 Multigigabit.
We recommend that you use only optical transceivers and optical connectors purchased from Juniper Networks with your Juniper Networks device.
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 EX4300 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 optics.
The transceivers support DOM even if they are installed in ports configured as Virtual Chassis ports (VCPs).
