摘要: An apparatus for measuring the characteristics of an optical fiber is provided. pulse generator generates, from a coherent light, first and second pulses having time interval which equal to or shorter tan life acoustic wave in fiber. A detector couples light with Brillouin backscattered includes lights belonging respectively, thereby generating signal. The further converts signal into electrical processor takes sum delay delayed by corresponding interval, interference signal, finds based on
