A Cisco QSFP-4X10G-AOC3M compatible active optical breakout cable designed for high-speed data center interconnects. Connects a single QSFP+ port (40 GbE) to four 10G SFP+ ports and is fully hot-pluggable to minimize network disruptions. The fiber QSFP+ cable is lighter and more flexible than direct-attach cables, making it ideal for tight spaces and longer distances.
