OverviewApplicationsComparison with single-mode fiberTypesEncircled fluxExternal links

The equipment used for communications over multi-mode optical fiber is less expensive than that for single-mode optical fiber. Because of its high capacity and reliability, multi-mode optical fiber is generally used for backbone applications in buildings. An increasing number of users are taking the benefits of fiber closer to the user by running fiber to the desktop or to the zone. Standards-compliant architectures such as Centralized
