Prysmian Group: the only manufacturer to produce colour coded 180µm fiber optic 2 Fiber optic cannot be used without being part of an optical cable. An optical cable contains 1 to 6,912 fiber optic, and is designed to appropriately protect the fibers, depending on where and how the cable is installed. Primarily, each fiber is required to be colour coded accordingly, otherwise it cannot be used in an optical cable. This is simply because, unless the cable contains only one fiber, it would be impossible to indicate the use of each individual fiber at both cable ends without a colour code. This is similar to how we identify different electrical wires.
