DEVICE FOR DETECTING AND LOCATING TRANSMISSION FAULTS IN HYBRID FIBER COAX (HFC) NETWORKS AND METHOD FOR USING SAME

摘要

The invention relates to a device for detection and location of defects of transmission in the networks of the hfc type, and a method of implementation of this device. A means (1) of transmission, produces a pulse signal (p) which is injected in the descending path of the network. This pulse signal (p) causes an intermodulation, in the network equipment, which causes the formation of an echo signal (e) transferred on the channel rising to a reception means (4). A system (7) of control makes it possible to control the means (1) of transmission and the processing of the echo signal (e).
