Singlemode fiber (SMF) has a very small core—around 8 to 10 microns —that allows only a single light mode to travel directly through the cable. Because the light does not bounce around, signal distortion is minimal, enabling long-distance transmission with high bandwidth. In fiber-optic communication, a single-mode optical fiber, also known as fundamental- or mono-mode,is an optical fiber designed to carry only a single mode of light - the transverse mode. Modes are the possible solutions of the Helmholtz equation for waves, which is obtained by combining. The basic principle behind single mode fibers lies in their ability to confine light within a small core diameter.
