HPE JH234A X242 40G QSFP+ to QSFP+ 1m Direct Attach Copper Cable
Overview
The HPE X242 is a high-performance, passive Direct Attach Copper (DAC) cable engineered for reliable 40GbE network connectivity in high-density data center environments. It provides a cost-effective and power-efficient solution for establishing short-range links between servers, switches, and storage arrays equipped with QSFP+ ports. This cable is specifically designed to address the demand for high-bandwidth, low-latency interconnects, making it an ideal choice for top-of-rack (ToR) and adjacent-rack deployments where performance is critical. It eliminates the need for more expensive and power-consuming optical transceivers for short distances. At its core, this 1-meter cable leverages advanced twinaxial copper wiring to ensure signal integrity and deliver full 40 Gbps bidirectional throughput with minimal latency. Its passive design means it draws negligible power, contributing to lower operational expenditures and a reduced thermal footprint within the rack—a significant benefit for large-scale deployments. The pre-terminated QSFP+ connectors offer a plug-and-play experience, ensuring seamless compatibility and interoperability with a wide range of HPE networking equipment and other industry-standard devices. Engineered for reliability, the cable is hot-swappable, allowing for installation and replacement without network downtime. Its durable construction is built to withstand the rigors of data center operations, ensuring a secure and stable physical connection. The fixed 1-meter length is optimized for connecting devices within the same rack, which helps to minimize cable clutter, improve airflow, and simplify cable management. Management is inherently simple as the cable is a passive physical layer component, requiring no software or configuration.
