Abstract

Measurement of the Raman gain coefficient in optical fiber is important for the design of new fibers to be used in 1.3-μm Raman amplifiers, generation of 1.48-μm light for remote pumping of erbium-doped fiber amplifiers (EDFAs), and the calculation of cross talk in long-haul wavelength-division multiplexing (WDM) systems. Our technique, in which we measure the larger stimulated Raman signal, directly gives the Raman gain coefficient and dispersion of the fiber without the need for calibration or absolute measurement of the Raman signal
