Multi-mode (mm) fibers have large optical cores that can carry multiple modes, or paths, of light. Their main applications include telecom and audio/video links. Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be. Multimode Fiber (MMF) has a core diameter, typically 50–100 micrometers, has ability to transfer multiple modes of light through the fiber core, uses lower-cost electronics (LED, VCSEL) operates at the 850 nm and 1300 nm wavelength and is used for short distance interconnections (up to 550m). Single mode fiber optic cable is made up of a small diameter glass or plastic core surrounded by cladding, which is a layer of reflective material. These feature a small modal dispersion for vast-distance signal transmission. In contrast with multimode fiber, single. Singlemode (SM) and multimode (MM) fiber optic cables are two core fiber types distinguished by core diameter, light propagation mode structure, attenuation performance, and transmission distance.
