Locating Cable Faults
One of the challenges in underwater cable faults is locating the exact placement of the actual fault (i.e. break). Similar to basic wire faults, a Time-domain reflectometer is used to identify the distance to the fault from a specific site. Time Domain Reflectometry involves sending a signal down the undewater cable line and then capturing the reflected signal. By comparing the original signal with the reflected signal, a mathematical algorithm can provide the distance to the cable fault.
