NOTE: This topic does not describe which devices support these transceivers.
For information about which transceivers are supported on QFX Series devices,
see the following topics:

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 36 on page 122 describes the passive QSFP+ DAC breakout cable specifications.
•
Active DAC cables have signal amplification and equalization built into the cable
assembly.
Table 37 on page 123 describes the passive QSFP+ DAC breakout cable
specifications.
