Abstract
A cable signal detector for being provided at a connector at an end of a communication cable transmitting differential signals or at a relay connector to be connected to the connector to detect an existence of information communication. The cable signal detector includes an amplifier circuit that branches and extracts a portion of a signal transmitted through the communication cable, amplifies the extracted signal and outputs the amplified signal, and a display portion that display the existence of information communication based on the output of the amplifier circuit. The amplifier circuit is mounted on a detection device formed separately from the connector or the relay connector. The connector or the relay connector is configured to transmit the extracted signal to the detection device.
