Abstract
Provided is an Active Optical Cable (AOC) device for short-range optical communication. The AOC device includes an electrical wire between a transmitter and a receiver for the feedback of a monitoring signal from the receiver. The receiver further includes a monitoring circuit to control the compensation of a high frequency component of an equalizing filter, acquire the result of receiving signal size determination and a high frequency component compensation from the equalizing filter, and perform the feedback of the acquired monitoring signal to the transmitter through the electrical wire. The transmitter further includes a transmitter control circuit to receive the feedback monitoring signal from the receiver through the electrical wire and control a high frequency component control code of the high frequency component control circuit and an optical signal output size control code of the optical device driving circuit based on the received monitoring signal.
