Fiber Optic Cable Manufacturing Process The manufacturing process of optical fiber cables consists of several stages, including fiber production, cable sheathing, cable assembly, and testing. Fiber production involves the drawing of glass or plastic fibers from preforms. “We are constantly working to refine our processes down to the very last detail. Unlike traditional copper cables, fiber optic cables use light signals to transmit data, which allows them to carry large amounts of information at extremely high speeds. Fiber optic cables have revolutionized data transmission, providing high-speed, reliable communication over long distances.
