QSFP Cable Overview
Every 4700 port on the switch is equipped with transmit and receive circuits that can adjust to
fit different types of link characteristics and either optical or copper cables.
The QSFP cables transmit and receive up to 10 Gbps per channel (total: up to 40 Gbps per
port) over a single active/passive optical or copper cable, Passive copper cables do not
consume any additional power while active copper and optic cables consume up to 2.5 Watt.
You can use the QSFP module with Copper or Optical cables. You can install any combination
of the cables in any of the QSFP cages.
