The optical frequency domain technique has been used in the analysis of discrete and distributed reflections in an optical fiber. To study discrete reflections, three examples are shown on a single-mode fiber: the first involves one reflector, the second and third examples use two and three reflectors in sequence. Another investigation is conducted on a 500-m multimode fiber to detect distributed reflections. This technique is suitable for recognition of the positions and properties of discrete reflections along an optical fiber.
