At the center of a fiber optic patch cable lies the core, which is composed of glass or plastic. This is the channel through which light flows. ZION Communication supplies both standard patch cords and custom assemblies to match your equipment, distance, and installation. A fiber-optic patch cord is a fiber-optic cable capped at each end with connectors that allow it to be rapidly and conveniently connected to telecommunication equipment. The wavelength range of visible light is: 390~760nm (nanometer), greater than the 760nm part is infrared light, and the part smaller. A fiber optic cable consists of five basic components: the core, the cladding, the coating, the strengthening fibers, and the cable jacket. They act as the critical link for interconnecting devices like optical switches, servers, and distribution frames.
