Overcomes the limitations of any mini OTDR or Optical Time Domain Reflectometer when used to accurately find a hidden event Locate the exact physical position of a hidden underground cable fault or break, within less than 1 meter, and over long distance! Reduces network hazard and days of labour as exploratory trenching is eliminated Minimises community disruption and excavation damage Finds faults and breaks in fibre cables where there is no visible evidence Minimises service disruption, since it can be used on a live system Field Proven.
