Abstract:
1. A device comprising: a connector configured to couple to an optical fiber; a light source coupled to the connector; a selector operable to change a mode between a distance test operating mode and a visual test operating mode; an oscillator that is operable in the distance test operating mode to send pulses of light from the light source to a first end of the optical fiber; a sensor coupled to the connector, wherein the sensor is operable in the distance test operating mode to detect light reflected by a fault in the optical fiber; a processor that is operable in the distance test operating mode to determine an estimated distance to the fault at a first site in response to the sensor detecting the light reflected by the fault, wherein the processor is further operable in the distance test operating mode, when the fault is not identified at the first site, to determine a second estimated distance while the optical fiber is bent near the first site, wherein a difference between the estimated distance and the second estimated distance is used to determine a second site; and a receiver configured to cause the selector to change the mode to the distance test operating mode in response to remote selection of the distance test operating mode and further configured to cause the selector to change the mode to the visual test operating mode in response to remote selection of the visual test operating mode, wherein the remote selection is wirelessly communicated to the receiver; wherein visible light from the light source is provided to the optical fiber in the visual test operating mode.
