The primary limitation of time-domain reflectometry (TDR) in detecting faults in long subsea cables is signal attenuation, which reduces the method's sensitivity and effective range for accurately locating faults over extended distances. Time-domain reflectometry (TDR) is a technique used to locate faults and characterize electrical cables by sending a pulse of energy down the cable and analyzing the reflections that occur due to impedance changes caused by faults or other anomalies. The distance to the fault is determined by measuring t....
