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.

Claim (Index 7):
A hybrid fiber coaxial (HFC) network fault locating apparatus, comprising:\n an input apparatus; a processor; memory configured to store a program and data; a communications bus is configured to establish connection and communication between the processor, the memory, and the input apparatus; and wherein the processor is configured to invoke the program stored in the memory to:\n obtain a fault group in a hybrid fiber coaxial (HFC) network, wherein the fault group comprises at least one fault point, \n control the input apparatus to collect a pre-equalization coefficient of at least one cable modem (CM), to obtain a first pre-equalization coefficient set, wherein the at least one CM is a CM whose pre-equalization coefficient changes after the fault group emerges, \n enable a reference fault point that is corresponding to the fault group and whose location is known, wherein the reference fault point is an impedance mismatch point that changes the pre-equalization coefficient of the at least one CM, \n control the input apparatus to collect the pre-equalization coefficient of the at least one CM again, to obtain a second pre-equalization coefficient set, \n calculate a relative distance between every two fault points in the fault group according to the first pre-equalization coefficient set, to obtain a first relative distance set, \n calculate a relative distance between every two fault points in a fault point set according to the second pre-equalization coefficient set, to obtain a second relative distance set, wherein the fault point set comprises the fault group and the reference fault point, and \n determine a relative distance between each fault point and the reference fault point according to the first relative distance set and the second relative distance set.
