Interface Specifications for QSFP+ DAC Breakout Cables for the QFX Series
Quad small form-factor pluggable plus (QSFP+) transceiver to four small form-factor
pluggable plus (SFP+) direct-attach copper (DAC) breakout cables are suitable for
in-rack connections between servers and the QFX Series.
You can use breakout cables purchased from a third party. These cables should meet
the specifications described in
Table 29 on page 80 . Table 28 on page 79 describes the
Junos OS software releases that supports third-party DAC breakout cables. Earlier releases
do not support third-party breakout cables.

The cables are hot-removable and hot-insertable. A breakout cable consists of a QSFP+
transceiver on one end and four SFP+ transceivers on the other end. The QSFP+
transceiver connects directly into the QSFP+ access port on the QFX Series device. The
cables use high-performance integrated duplex serial data links for bidirectional
communication on four links simultaneously. The SFP+ links are designed for data rates
up to 10 Gbps each. Passive breakout cables have no signal amplification built into the
cable assembly. There are two types of DAC cables:
•
Passive DAC cables have no signal amplification built into the cable assembly.
Table 29 on page 80 describes the passive QSFP+ DAC breakout cable specifications.
