As techniques for locating the fault point in the power feeding line of an optical submarine cable, the electric time domain reflector(TDR) is discussed. The location of the failure point of the power feeding line of the optical submarine cable can be measured using an electric time domain reflectometry (TDR). In TDR, round-trip time of an electric pulse is measured. However as the frequency dispersion...
As techniques for locating the fault point in the power feeding line of an optical submarine cable, the electric time domain reflector, and frequency domain reflectometry are discussed. In this paper, we will discuss time domain analysis and compare simulated and actual measurements. We will also discuss the pulse propagation velocity of a single sinusoidal wave used for TDR measurement. The analytical...
