Cable Specifications on page 141
QSFP+ passive DAC 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 DAC cables have no signal
amplification built into the cable assembly. For the full specifications of these cables,
see
The Hardware Compatibility Tool
Table 75 on page 141 describes the support for QSFP+ passive DAC cable lengths on
EX Series switches for Junos OS releases.
