Cable Specifications
NFX150 devices support SFP+ passive DAC cables. The passive Twinax cable is a straight
cable with no active electronic components. NFX150 devices support 1 m, 3 m, and 5 m
long SFP+ passive DAC cables.
NOTE: We recommend that you use only SFP+ DAC cables 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 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.
