HPE JH235A X242 40G QSFP+ to QSFP+ 3m Direct Attach Cable

Detailed Specifications

The HPE X242 is a high-speed, direct-attach copper cable designed to provide reliable 40 Gigabit Ethernet connectivity for in-rack and adjacent-rack deployments. It serves as a critical link in modern data centers, connecting high-performance servers, storage arrays, and network switches over short distances. This passive cable assembly offers a straightforward, cost-effective, and low-latency alternative to optical transceivers, eliminating the need for separate modules and fiber patch cords, which simplifies purchasing and deployment. Engineered for performance, the cable assembly supports a data transfer rate of 40 Gbps, making it ideal for high-throughput applications where minimal delay is critical. It is built with high-quality twinax copper wire and features QSFP+ (Quad Small Form-factor Pluggable Plus) connectors on both ends. This ensures broad compatibility with a wide range of HPE networking equipment and other hardware that adheres to industry standards, providing a secure and stable physical connection. This 3-meter cable is primarily used for top-of-rack switch-to-server links or for interconnecting switches within a fabric. Its passive design means it consumes minimal power, contributing to lower operational costs and a reduced thermal footprint in dense rack environments. The plug-and-play nature of the JH235A simplifies network installation and upgrades, allowing IT staff to quickly establish high-bandwidth connections without complex configuration.
