HPE Networking X242 40G QSFP+ to QSFP+ 1m Direct Attach Copper Cable

Overview

The HPE JH234A is a 1 meter direct attach copper cable designed to provide 40 gigabit per second connectivity between devices with QSFP+ ports. It enables high-speed links without the need for separate transceivers, making it a practical choice for connecting switches, server adapters, or storage targets in close proximity. Its copper construction helps maintain low latency and reduces power consumption compared to optical cables, which benefits rack environments by lowering heat output and operating costs.

Key features

• Direct attach copper design eliminates the need for additional transceivers, simplifying setup and reducing costs.
• Compatible with HPE Aruba switches such as the 2930M access and CX 8360 core series, ensuring seamless integration.
• Ideal for switch stacking, short uplinks, and top of rack configurations where space and cable management are important.
• Low latency connection supports fast data transfer and responsive network performance.
• Reduced power draw compared to optical alternatives helps maintain cooler rack environments and lowers energy expenses.
• Durable build quality and a weight of approximately 0.41 kg keep the cable stable and secure once installed.
• Compact 1 meter length allows for neat routing without excess slack, improving airflow and organization.
