The invention discloses an adapter cable testing system capable of recognizing the addresses of tested devices. The adapter cable testing system comprises a testing host and a plurality of testing terminals, and the testing host and the detecting terminals are connected through a control bus. The adapter cable testing system is characterized by further comprising adapter cables, the testing terminals are connected with the tested cable devices through the adapter cables, resistors or chips used for recognizing the addresses are installed on plugs of the adapter cables, and the testing host automatically sorts out network connection tables of the tested cable devices through the resistors or the chips. According to the adapter cable testing system, the ID of the adapter cables connected to the tested devices can be automatically recognized, a tester does not need to connect the adapter cables to the specified testing terminals in a one-to-one corresponding mode but can carry out flexible configuration according to the testing field, it is only needed to connect the tested cables to the testing terminals, the intelligent cable testing recognizing function can be achieved, mistaken connection and connection omission are prevented, and the testing efficiency and accuracy of cable testing can be more effectively improved.
