What is an Active Optical Cable?
An Active Optical Cable (AOC) is a hybrid cable that combines electrical interfaces (like copper cables) with optical fiber for data transmission. It uses integrated "opto-electronic converters" at both ends to convert electrical signals into light (and vice versa), enabling high-speed, long-distance communication while maintaining compatibility with standard ports like HDMI, DVI,USB,Displayport or QSFP+ .

What is an Optical Cable?
An optical cable is a type of cable that transmits data via light pulses through glass or plastic fibers. Unlike traditional copper cables, optical cables are immune to electromagnetic interference and support higher bandwidths. AOCs are a specialized subset of optical cables with built-in active components for signal conversion.
What makes an AOC "Active"?
The term "Active" refers to the inclusion of "opto-electronic modules" (e.g., lasers, drivers) within the cable connectors. These components require external power to convert electrical signals to optical signals (and back), enabling signal amplification and extended transmission distances. Passive cables, like copper-based Direct Attach Cables (DACs), lack these components and are limited to shorter ranges .
