HPE Aruba Networking 100G QSFP28 to QSFP28 1m Direct Attach Copper Cable

Overview

The HPE R0Z25A is a 1-meter direct attach copper cable designed to carry 100 gigabit signals using QSFP28 connectors on both ends. It provides a cost-effective and efficient solution for connecting devices within the same rack, eliminating the need for optical transceivers. This cable is ideal for high-bandwidth applications such as switch stacking, leaf-spine links, and connecting top-of-rack servers to switches, delivering low latency and modest power consumption.

Key features

• Direct attach copper design that reduces latency and power usage compared to optical alternatives
• QSFP28 connectors on both ends enable straightforward plug-and-play installation without extra transceivers
• Optimized compatibility with HPE Aruba 8325-32C and 8325-48Y8C switches for seamless integration
• Fixed 1-meter length helps maintain clean cable management and minimizes signal loss on short runs
• Lightweight and durable with a black outer jacket, suitable for dense data center environments
• Supports high-speed 100 Gbps throughput for demanding network traffic within racks

Connectivity and compatibility

This cable is designed to connect directly to QSFP28 ports on compatible HPE Aruba switches, including the 8325-32C and 8325-48Y8C models. It supports high-speed links within the same rack, making it a practical choice for data centers that require reliable and efficient short-range connections. The direct attach copper design ensures low latency and power consumption, which is critical for maintaining performance in dense networking setups.

Ideal uses and environments

The HPE R0Z25A fits well in data center environments where short-range, high-bandwidth connections are needed. It is particularly suited for switch stacking, leaf-spine network architectures, and linking top-of-rack servers to switches. Its 1-meter length and copper construction make it a strong choice for setups that prioritize low latency and energy efficiency without the complexity of optical transceivers.
