Abstract
A USB active optical cable and a plug capable of managing power consumption and state. The USB active optical cable and plug respectively comprises a first plug, a second plug, and an optical transmission medium used to connect the first plug and the second plug; the first plug and the second plug are configured to operate different operating states, including an initialization mode, a transmission mode, and a power saving mode, and they can switch between the different operating states. The USB active optical cable and plug are both based on the separate control of the transmitting unit and the receiving unit to distinguish different operating modes, provide necessary operating requirements and mode switching conditions for each mode, and also enable the checking and transmission of the plugging state in the power saving mode, thus facilitate the power consumption management of the active optical cable.
