Abstract

P-OTDR is the effective method for measuring distribution of PMD in a single-mode fiber, this paper analysis the effect of coherence of light source on measurement, that, when the width of input pulse is short enough, this effect can be neglected. But, when we estimate the effect of width of pulse on the measurement results, the coherence of light source must be considered.
