Abstract
An offline phase of a cable length measuring method involves a determination of a plurality of preset frequency test signals for facilitating the length measurement of the cable based on a maximum measurable length of the cable. An online phase minimally involves a measurement of the length of the cable based on a first reflected phase shift between a first preset frequency test signal as transmitted at a transmission end of the cable and a first preset frequency reflection signal representative of a reflection of the first preset frequency test signal at a reflection end of the cable, and based on a second reflected phase shift between the second preset frequency test signal as transmitted at the transmission end of the cable and a second preset frequency reflection signal representative of a reflection of the second preset frequency test signal at the reflection end of the cable.
