Keep 40 GbE links tight, clean, and predictable with Cisco’s 1 m active optical cable. Designed for short-reach interconnects in high-density racks, it gives infrastructure teams a practical alternative to bulky copper assemblies when port spacing and cable routing are constrained. This cable is a strong fit for switch-to-switch, switch-to-server, and top-of-rack deployments where a short, fixed-length connection is all that’s required. The active optical design helps maintain signal quality over the link while reducing the clutter that can slow down maintenance and obscure airflow paths. For teams standardizing on Cisco optics and cabling, this part supports a more controlled physical layer strategy. It is especially useful in environments where consistency, rack cleanliness, and dependable 40 GbE connectivity justify choosing a vendor-qualified cable over lower-cost generic options. When the link is short but the requirement is strict, this cable keeps the connection simple and professional. Ideal For Connect adjacent switches in a top-of-rack deployment Link servers to a nearby aggregation switch in the same rack Patch 40 GbE ports in dense data center cabinets Replace short copper runs where cleaner cable routing is preferred Why This Product 1 Optical short-reach design instead of bulky copper cabling 2 Fixed 1 m length for predictable rack routing 3 Cisco-qualified part for compatible 40 GbE deployments 4 Better fit for dense cabinets where airflow and cable control matter
