An AOC cable is a type of interconnect that uses optical fiber media inside the cable, but the transceivers (optical–electrical conversion) are integrated into its ends. Hence, active. An Active Optical Cable (AOC) is a high-speed data transmission cable assembly type. It combines electronics transceivers with fiber optics, surpassing the speed and reliability of copper-based connections. Standard connectors (SFP+, SFP28, QSFP+, QSFP28, QSFP-DD, OSFP). The purpose of this manual is to give a complete understanding of AOCs, including how they work at their core level, where they can be. In simple terms, an active optical cable has modules at either end of an optical fiber cable that allows direct communication between devices over that permanently attached fiber cable.
