The Huawei SFP+STACK-CU1M5 is a dedicated SFP+ stacking Direct Attach Copper (DAC) cable engineered to interconnect Huawei switches within a unified stack. With a length of 1.5 meters, it is ideal for short-distance switch-to-switch connections inside racks or between adjacent racks, enabling multiple switches to operate as a single logical device. This enhances network scalability, simplifies management, and improves resilience by ensuring rapid failover and unified configuration across the entire stack.The cable features SFP+ connectors on both ends and supports 10-gigabit transmission over a high-quality passive twinax copper conductor. As a passive DAC cable, it requires no additional electrical power, providing an energy-efficient and cost-effective solution for stacking scenarios while reducing heat output in dense environments.
Its durable jacket and shielded construction ensure excellent electromagnetic interference protection, stable electrical characteristics, and consistent low-latency performance. The flexible cable structure facilitates easy installation, optimal routing, and reduced mechanical strain on switch ports.
Designed to meet Huawei’s standards for switch stacking, the SFP+STACK-CU1M5 ensures reliable synchronization between stack members, allowing seamless load balancing, unified management, and rapid recovery in case of hardware failure. It is an ideal choice for enterprise networks, campus infrastructures, and data center deployments requiring dependable and high-performance stacking connectivity.
