Abstract
Synchronous capture of a forward signal and a related CPD signal at a remote PHY device (RPD) for detecting and locating CPD is disclosed. The RPD delivers the forward signal to a coaxial cable plant. The forward signal propagates from the RPD to a CPD source and the CPD signal propagates from the source to the RPD within a round-trip interval. The steps include: (a) capturing the forward signal from the RPD during the round-trip interval; (b) generating a reference signal, substantially simulating the CPD signal, from the forward signal; (c) supplying the reference signal to the RPD; (d) receiving the reference signal in the RPD via a return channel; and (e) capturing the CPD signal at the RPD in the return channel during the round-trip interval. Reference and actual CPD signals are processed as a combined return signal for detecting CPD.
