The HP 498385-B21 is a 1-meter, quad data rate (QDR) copper cable equipped with Quad Small Form-factor Pluggable (QSFP) connectors, designed for high-speed data transfers between networking equipment. This cable is perfectly suited for connecting InfiniBand technology-based systems, including switches, routers, and high-performance computing (HPC) clusters, facilitating data rates of up to 40 Gbps. Its construction is optimized for durability and minimal signal loss, ensuring reliable, high-quality connections over its entire length. The use of copper for the cable provides a cost-effective, lower-power alternative to fiber optic cables, while still delivering the high bandwidth and low latency that critical applications require. Suitable for short-range connections within data centers, this cable supports the demands of data-intensive applications such as data mining, real-time analytics, and high-frequency trading operations. The HP 498385-B21 cable is an essential component for IT professionals aiming to achieve efficient, high-speed networking performance in environments that utilize InfiniBand technology or other compatible interconnects.
