Quad small form-factor pluggable plus transceiver (QSFP+) to 4 SFP+ direct attach copper breakout cables are suitable for in-rack connections between servers and QFX3500 switches.

The cables are hot-removable and hot-insertable. A breakout cable consists of a cable assembly that connects directly into a QSFP+ module on one end and four SFP+ modules on the other end. The cables use 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.
