NOTE: We recommendthat youuse onlySFP+ directattach cables purchased
from Juniper Networks with your Juniper Networks device.
CAUTION: If you are having a problem running a Juniper Networks device
that is using 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 cables are hot-removable and hot-insertable: You can remove and replace them
without powering off the switch or disrupting switch functions. A cable comprises a
low-voltage cable assembly that connects directly into two SFP+ ports, one at each end
of the cable. The cables use high-performance integrated duplex serial data links for
bidirectional communication and are designed for data rates of up to 10 Gbps.
