Is single-mode fiber generally universal
But not all fiber cables are created equal: multimode (MM) and single mode (SM) fibers are the two primary types, each engineered for specific use cases, from short-range data center connections to transcontinental telecom backbones. 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. Larger cores, by contrast, allow many spatial modes to travel simultaneously, each following a slightly different optical path. They both have their sweet spot, and knowing which one fits your organization's needs can help you make the right choice.
