Move 40 GbE traffic across short distances without filling the rack with excess copper or oversized patch bundles. This AddOn active optical cable connects a QSFP port to 4x SFP+ endpoints over 10 m, giving infrastructure teams a practical way to link high-density switching and server aggregation gear. Compared with separate transceivers and fiber patch cords, an AOC simplifies the physical layer. The cable arrives as a single assembly, which reduces component count, shortens install time, and helps keep cable paths organized in crowded cabinets. That matters when you are building or refreshing a fabric where airflow, serviceability, and port density all compete for space. The 40GBASE-AOC design is well suited to short-run interconnects that still need the reach and signal characteristics of optical transport. It is a strong fit for top-of-rack and end-of-row architectures, especially where teams want a cleaner alternative to bulky copper at 40 GbE speeds. Choose this cable when you need a compact, purpose-built link that supports high-throughput connectivity and keeps the rack easier to manage over time.
