ABSTRACT:
An optical fiber monitoring method and apparatus is described for monitoring the signal loss within an optical fiber during installation of the optical fiber. The apparatus contains a jig for advancing the optical fiber along a predetermined path, a light source for transmitting light signals along the optical fiber, and a light sensor for detecting the light signals. The detected light signals are converted to an audible signal having a frequency which varies in relation to the detected signal. An audio transducer then outputs the audible signal. Since the frequency of the audio signal is a measure of the signal loss along the optical fiber and, therefore, is a measure of the amount by which the optical fiber is bent during the installation process, the audible signal can be monitored in an "eyes-free" manner to detect excessive bending of the optical fiber in order to prevent damage to the optical fiber during installation.
