Keep short-range 10 GbE infrastructure simple, compliant, and predictable with the AddOn HP 487649-B21 compatible direct attach copper cable. This SFP+ to SFP+ DAC is designed for direct connections between compatible network devices, reducing the need for separate optics and fiber while preserving the throughput required for server access, top-of-rack switching, and storage connectivity. For teams standardizing on approved procurement paths, the TAA-compliant design supports public sector and regulated enterprise environments without adding complexity to the bill of materials. Direct attach copper is often the right choice when the link spans a rack or two and the priority is dependable performance, lower power draw, and simpler deployment. AddOn’s compatibility-focused approach makes this cable a practical fit for infrastructure teams that need to extend 10 GbE links without overbuying on transceivers. Use it where short-reach connectivity must be clean, fast, and easy to provision. It is a straightforward way to connect SFP+ ports in dense environments while keeping costs aligned to the actual distance requirement.
