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. The
Hardware Compatibility Tool and Table 47 on page 137 describe the passive QSFP+
DAC breakout cable specifications.
•
Active DAC cables have signal amplification and equalization built into the cable
assembly. The Hardware Compatibility Tool and Table 48 on page 138 describe the
passive QSFP+ DAC breakout cable specifications.
