Product Description
This HP 5m 100Gb QSFP28 to QSFP28 cable is built for high-speed, short-distance connections in data centers and enterprise networks. It’s often found in environments where reliable 100Gbps links between switches, routers, or servers are needed without the complexity of optical transceivers. Designed primarily for network engineers and IT professionals, this cable streamlines setup by offering a plug-and-play solution with minimal signal loss. It’s commonly used in top-of-rack, end-of-row, or spine-leaf network architectures where efficiency matters. Key Features Provides a stable 100Gbps connection over a 5-meter length Uses QSFP28 connectors for easy integration with compatible devices Maintains signal integrity with copper cabling optimized for short runs Ideal for data center switching and high-performance computing setups Reduces power consumption compared to equivalent optical links This cable is typically deployed inside server racks or between closely located network devices. Its robust build ensures consistent performance, helping maintain smooth data flow in demanding network environments.

Use Cases
The HPE 5m 100Gb QSFP28 to QSFP28 100GBase-CR4 Direct Attach Cable is ideal for high-density data center environments requiring low-latency, high-bandwidth interconnects over short distances. It is especially beneficial for IT teams managing rack deployments where direct server-to-switch or switch-to-switch connectivity is critical for performance-sensitive workloads. How It's Used: Connecting top-of-rack switches within enterprise data centers to support virtualization and cloud computing traffic. Linking storage clusters in hyper-converged infrastructure setups to ensure rapid data access and replication. Facilitating high-speed communications between network devices in financial services trading floors where minimal latency is essential. Interconnecting compute nodes in high-performance computing (HPC) environments requiring consistent 100Gbps throughput. Establishing direct server-to-server links in edge computing facilities to optimize processing near data sources. This cable supports operational efficiency by simplifying physical connectivity and reducing latency in critical network paths. Its compatibility with standard QSFP28 interfaces allows for scalable upgrading of network infrastructure without adding complexity to existing data center architectures.
