Preserve 40 GbE performance across longer interconnects with this 20 m active optical cable from UNC GROUP. Built for QSFP+ to 4x SFP+ breakout deployments, it supports dense switch-to-server and switch-to-switch topologies where clean signal delivery matters more than cable cost alone. The optical design helps avoid the attenuation and reach limits that can constrain passive DAC options in larger racks or adjacent rows. For infrastructure teams standardizing on Arista environments, this cable provides a practical path for connecting a single 40G uplink to multiple 10G endpoints without adding transceivers and patch cords at each end. That reduces cable clutter, simplifies port mapping, and keeps airflow more predictable in crowded cabinets. The 20 m reach gives you room to route cleanly through overhead trays or across aisles while maintaining a direct, point-to-point link. Choose this AOC when you need dependable breakout connectivity with the physical flexibility of fiber and the simplicity of an integrated assembly. It is a strong fit for production networks where link stability, rack density, and installation speed all matter.
