Precise measurement of refractive index profile of an optical fiber is crucial for the measurement of different characteristics, such as the signal bandwidth of the fiber. We present a simple and inexpensive method for mapping the refractive index profile of an optical fiber. This method uses an interferometric technique to map the refractive index profile of a fiber. Comparing the index profile simulated theoretically with the experimental one, the difference between the refractive index of clad and that at the center of core for a graded index fiber was found to be 0.018. This technique also enables one to determine whether the fiber is a step index fiber or a graded index fiber.<>
