Let's start with AOC, which stands for Active Optical Cable. The optical module and optical cable are integrated, and laser components are required for both ends' optical modules. The acronym AOC represents Active Optical Cable and can also fall in the category of a Transceiver, SFP (Small Form-factor Pluggable) or QSFP (Quad Small Form-factor Pluggable) modules, TOSA (Transmit Optical Sub-assembly, ROSA (Receive Optical Sub-assembly), etc. DAC can be further categorized into active ACC, AEC, and passive DAC. So, what exactly are these solutions and how do they. Active Optical Cables (AOC) use optical fibers, allowing for longer distance transmission compared to copper cables and being less susceptible to electromagnetic interference.
