Single-mode optical cables and multimode fibers can both employ either a step-index refractive index profile or a graded-index profile; single-mode fibers, however, predominantly use the step-index profile. Consequently, quartz optical fibers can generally be classified into three types: multimode step-index fibers, multimode graded-index fibers, and single-mode step-index fibers. The propagation of light—as an electromagnetic wave—within an optical fiber constitutes guided wave propagation in a dielectric cylindrical waveguide. When total internal reflection occurs at the interface between media, the electromagnetic wave is confined within the medium, a phenomenon known as guided wave or guided mode. For a given guided wave and operating wavelength, multiple incident conditions can satisfy the condition for total internal reflection, corresponding to different modes of the guided wave. Based on the number of propagating modes, optical fibers are categorized as multimode fibers and single-mode fibers. Multimode fibers can support the propagation of several modes, whereas a single-mode fiber can support only a single mode at a specified operating wavelength.
