The conceptual characteristics of multimode optical fiber
Multi-mode fiber has a fairly large core diameter that enables multiple light modes to be propagated and limits the maximum length of a transmission link because of modal dispersion. Multi-mode optical fiber is a type of optical fiber mostly used for communication over short distances, such as within a building or on a campus. Multimode fiber (MMF) continues to play a critical role in today's high-bandwidth, short-range optical networks. Mul-timode fiber (MMF) operated at 850 nm is the leading optical medium now used in DCs for distances up to 100–150 m, enabling utilization of vertical-cavity surface-emitting lasers (VCSELs) to provide low-cost optical connectivity compared to single-mode fiber solutions.
