WHY CHOOSE THIS PRODUCT?

• Organizations choose the Cisco QSFP breakout cable when they need a cost-efficient and scalable method to expand 10G connectivity from existing 40G switch infrastructure. It allows a single high-speed port to serve multiple endpoints, maximizing hardware efficiency and reducing overall infrastructure cost.
• Compared to separate transceiver-based connections, this passive copper solution eliminates additional optics, lowering power draw, simplifying cable management, and improving operational efficiency. It is especially beneficial in environments where rapid scaling of server-to-switch connectivity is required without redesigning the entire network architecture.
