This topic describes:
Cable Specifications on page 133
QSFP+ passive direct attach cables are hot-removable and hot-insertable. A cable
consists of a cable assembly that connects directly into two QSFP+ modules, one at
each end of the cable. The cables use integrated duplex serial data links for bidirectional
communication and are designed for data rates up to 40 Gbps. Passive direct attach
cables have no signal amplification built into the cable assembly.
Table 74 on page 133 describes the support for QSFP+ passive direct attach cable lengths
on EX Series switches for Junos OS releases.
NOTE: We recommend that you use only QSFP+ direct attach 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
