Unlike traditional copper Direct Attach Cables, an AOC cable can carry hundreds of gigabits per second over tens of meters with virtually no signal loss. For example, QSFP‑DD AOC cables pack eight 50Gb/s VCSEL lanes into one link, enabling a 400G AOC cable that replaces four 100G. As data center speeds grow from 10G → 25G → 100G → 400G → 800G, the choices for server-to-switch interconnects become more complex. Today, IT teams typically pick between three options: DAC (Direct Attach Copper) – cheapest, short-distance. As. Those speeds usually range between 10 and 100 Gigabits per second, and if that describes your network, then you have several viable options for how you connect your devices. One option is that of active optical cables. They can provide powerful, cost-effective connectivity for many different. Fiber NICs come with pluggable cages that accept optical transceivers or direct-attach cables. Fiber NICs can accept a variety of media. Explore Amphenol's high-speed Active Optical Cables designed for data centers, HPC, telecom, and storage systems with support from 12G to 400G. Amphenol is a leading innovator in the development and manufacturing of Active Optical Cables (AOCs), delivering high-performance interconnect solutions. Advanced AOC cables support very high speeds (25G, 40G, 100G, 200G, even 400G) in data center environments.
