This paper proposes a new method for measuring a longitudinal distribution of the Raman gain efficiency in concatenations of single-mode optical fibers by using a backscattering technique and a pulsed pump light. The advantage of this method is that it can provide us with an easy way of evaluating optical fiber networks because we can measure from only one end of optical fibers. We perform an experiment employing this method and confirm that it can be used to measure Raman gain efficiency distribution easily.
