Keep high-speed links tight, predictable, and easy to service with this 40G-CR4 QSFP active DAC cable. Built for Cisco-compatible QSFP environments, it delivers a direct-attach copper connection for 40 GbE links over 2 m, making it a practical choice for adjacent rack equipment and short interconnect runs. Active DAC design helps maintain signal quality across the cable length while avoiding the cost and complexity of separate optics and fiber patching. That makes it well suited for dense infrastructure where port availability, cable management, and latency all matter. For teams standardizing on short-reach 40 GbE, this cable offers a clean path between switches, servers, and storage systems without adding unnecessary components. Use it where fast deployment and tidy rack layouts are more valuable than long-distance reach. The QSFP interface supports straightforward installation in compatible hardware, while the copper construction keeps the link simple to provision and maintain. For enterprise environments, that combination helps reduce points of failure and keeps high-throughput connections close to the equipment they serve.
