Abstract

We present a fault locator developed for diagnosing an optical fiber transmission line. This locator works under the principle of phase—modulating optical coherence domain refiectometry, and as a precisely tunable light source it takes a fiber loop including an EDFA and a frequency shifter. By optimizing the characteristics of this light source, spatial resolution of 10cm is demonstrated.
