Lenovo 78P4418 3 m Active Optical Cable for PCIe3 Expansion | Enterprise

Place PCIe3 expansion hardware where the rack design works best, not where a short copper cable allows. This 3 m active optical cable is designed to carry high-speed PCIe3 expansion links over a longer span while helping preserve signal integrity and reducing the physical constraints that come with direct-attached cabling. For infrastructure teams, the value is practical: cleaner cable routing, more freedom in chassis placement, and fewer compromises when building dense systems. Active optical construction is especially useful when expansion cards, enclosures, or accelerator modules must be separated by distance that would challenge passive cabling. In enterprise environments, that flexibility can simplify serviceability and improve layout discipline. It supports installations where airflow, access, and cable management are part of the performance equation. When the system design calls for a longer PCIe3 expansion run, this cable provides a purpose-built path that is more suitable than generic interconnect options.
