description The invention provides a method and device for optical fiber measurement, and the method comprises the steps: determining the energy transfer size of a first SRS according to the energy transfer relation between at least two kinds of service light and a corresponding OTDR pulse signal, the at least two kinds of service light comprise first service light and second service light, the first service light and the second service light are different in wavelength or power, and the first service light and the second service light are different in wavelength or power; the first service light and the first OTDR pulse signal are transmitted at the same time, and the second service light and the second OTDR pulse signal are transmitted at the same time; and generating a target OTDR test curve according to the first OTDR test curve and the first SRS energy transfer size for optical fiber measurement. By measuring the OTDR test curves under different service lights and the energy relation of different service lights, the
