Abstract
Embodiments of the present disclosure disclose a hybrid fiber coaxial (HFC) network fault locating method and apparatus. The method includes: obtaining a fault group in an HFC network; collecting a pre-equalization coefficient of at least one cable modem (CM); enabling a reference fault point that is corresponding to the fault group and whose location is known; collecting the pre-equalization coefficient of the at least one CM again; and determining a relative distance between each fault point in the fault group and the reference fault point according to the pre-equalization coefficient collected twice. In the present disclosure, not only each fault point in a fault group including a plurality of fault points can be located, but also a fault group including only a single fault point can be located.
