Cable Fault Locators

GAOTek’s fault locators are precise and practical devices which provide an immediate display of the location and distance of the break in pair wires and cables both under and above ground level. These high-quality and portable field instruments make use of time domain reflectometer (TDR) and bridge methods, which adopts advanced micro-electronics technology. They are designed to measure the exact fault location and distance for under and above ground telecommunication covered with sheathed, plastic or lead wires. GAOTek’s cable fault locators are effective instruments for field staff, because it reduces labor intensity, and enhances work efficiency and precision.


Cable fault distance locators can locate some hidden, underground and out of reach cables with ease and quickly. These locators can solve the issues as early as possible by sending signals down to the investigation area, then calculating and determining the distance and exact location of the fault from the base station. Afterwards, the information will be delivered to the users via the LCD display. They are mainly used in the line project acceptance tests and inspection of cables.  Also these devices are widely used in testing underground cables to find out impedance break points, to locate the distance to cable damages, and reveal terminal impedance failures. It helps technicians by decreasing investigation time, enhancing work proficiency, and lessens workload of line installation or maintenance.


GAOTek’s cable fault detectors are user-friendly, portable, lightweight, and compact. The high-quality and affordable devices feature auto key that allows engineers to get test results instantly after setting the proper parameters. Moreover, they have USB and sometimes RS-232C interface for waveform transmission and analysis. Cable fault locators have a unique feature of automatic placement of measuring cursor at fault point in auto mode. These devices are weatherproof and have large LCD display for easy visualization. Essentially, it provides maximum technical safety and support successful operation.

Applications and Industries

Cable fault detectors are widely used as the solution to install, analyze, and identify fault points in HFC systems. Cable fault locators are used in the industries such as data communications, video communications, networks, testing, maintenance and technical services, communications infrastructures of hydro, oil, gas, and mining industries.
