Abstract
In accordance with the teachings of the present invention, a method and apparatus is presented for troubleshooting a fiber-optic cable. A fiber-optic, cable-troubleshooting system includes an integrated Optical Time Domain Reflectometer (OTDR) for generating an optical distance to a fault and a cable-locating module for presenting a tone on a fiber-optic cable. A technician uses the tone to locate the fiber-optic cable and the optical distance to locate the fault in the fiber-optic cable.
