A trunk cable is a type of fiber optic cable that can carry large amounts of data at once through a telecommunications system. It acts as the “backbone” or main line of communication within a network, connecting different areas together while preserving signal quality over long. In modern telecommunications and data transmission systems, fiber-optic trunking cables are of great importance as they offer fast connections and reliability. Several optical fibers are contained in these cables, which are enveloped by a protective covering to ensure that information is. Trunk cables are one of the essential elements in any fiber optic communication network, since they serve as a physical conduit, pipeline or circuit for an optical fiber connection. Instead of running 12 separate cables between two cabinets, you can run one trunk cable with 12. Discover our wide range of U-DQ trunk cables as variant with LC or SC connectors, for example, in categories OS2, OM2, OM3, OM4 and OM5.
