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 SFP+, and QSFP+ transceivers installed in EX4650 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.
NOTE:
The transceivers support DOM even if they are installed in the SFP+ uplink module ports.
SFP28 Direct Attach Copper Cables for EX4650 Switches
IN THIS SECTION
Standards Supported by These Cables | 67
Small form-factor pluggable transceiver (SFP28) direct attach copper (DAC) cables, also known as Twinax
cables, are suitable for in-rack connections between servers and switches. They are suitable for short
distances, making them ideal for highly cost-effective networking connectivity within a rack and between
adjacent racks.
NOTE:
We recommend that you use only SFP28 DAC cables purchased from Juniper Networks
with your Juniper Networks device.
