An integrated on-line cable-monitoring technique for hybrid fiber/coaxial (HFC) networks is proposed and experimentally demonstrated. The in-service monitoring of fiber optic cable and coaxial cable is achieved simultaneously by an optical time-domain reflectometer (OTDR) and the frequency domain analysis (FDA) method, respectively, where the FDA results are encoded in the additional dummy fiber through digitally modulated fiber benders. This technique can be easily developed into an automated in-service surveillance system to provide real-time monitoring to enhance HFC network reliability.
