摘要： A hand-held instrument uses a red laser to both provide a visual indication to the user of where a fault is present along an optical fiber, and a distance measurement to the user where the fault is present along the optical fiber. The instrument provides a single bulkhead to which the optical fiber is attached to accomplish this dual functionality. The instrument passes a beam of red light into the optical fiber. When the red light encounters a fault in the optical fiber, the red light is emitted from the optical fiber so that the user can visually detect the fault. In addition, the red light is reflected back to the instrument and the instrument determines and outputs a distance measurement at which the fault is located.
