frequency and type of pulse for time domain reflectometer (TDR)

WebTDRs basically require two parallel wires. Usually this is a center conductor and shield (or neutral), which is most comonly a cable with concentric construction. However any set of parallel wires can work, phase to phase (leg to leg) etc. It is usually fairly straight forward to verify if a TDR will or will not work in most applications. WebWhat Is ODTR? Optical Time-Domain Reflectometer (OTDR) is an optoelectronic instrument used to characterize an optical fiber. It can be considered as the optical equivalent of an electronic time-domain reflectometer. OTDR injects a series of optical pulses into the fiber under test. It also extracts, from the same end of the fiber,light that is ... flushing self storage
