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.
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.
