Components of the fiber optic patch cord (cable assembly) The majority of our customers manufacture fiber optic cable assemblies, which are widely known as patch cords. Patch cords can be simplex or duplex. A simplex cable consists of a single strand of optic fiber. A duplex cable is composed of. A fiber-optic cable, also known as an optical-fiber cable, is an assembly similar to an electrical cable but containing one or more optical fibers that are used to carry light. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube. The patch cord consists of three parts: fiber optic cable, housing, and ferrule. Fiber Optic Cable Light is an electromagnetic wave. 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 are generally sold in large quantities, rather than custom -made, although quite special models are also.
