An optical fiber cable includes pairs of transmission lines having length extensions and color coding to facilitate cable system assembly. Each transmission line is preferably constructed from unitary fibers including a P-type fiber and an N-type fiber with the length extensions of the same P-type and N-type fiber at each end respectively. The P-type fiber and the N-type fiber are preferably colored differently to indicate transmission direction. The P-type fiber and N-type fiber in one pair of transmission lines are preferably colored differently than the P-type fiber and N-type fiber in other pairs.

An optical fiber is colored to provide a striped pattern while maintaining a substantially uniform diameter of the fiber. In one embodiment, a coating of a first curable material having a base color is applied to an optical fiber core section using a coloring die. One or more stripes of a second curable material are applied using the die to the coating before the coating is fully cured. The stripe has a stripe color different from the base color and is formed in the coating such that the diameter of the fiber remains substantially uniform. In another embodiment, a tandem coloring system is used in which the coating is partially cured and one or more striping nozzles apply stripe(s) to the partially cured coating. In a further embodiment, the base color coating is applied and cured leaving one or more gaps. One or more stripes are applied in the gap(s) and cured to fully cover the fiber with a substantially uniform diameter.

System and method for coloring an optical fiber

An optical fiber cable is provided for undersea applications that include a hollow buffers tube with at least one optical fiber disposed therein. The buffer tube is formed from a plastic material. A water-blockable gel is located in the buffer tube and a series of strength members are configured in a close-packed arrangement around the buffer tube. A metal conductor surrounds the series of strength members and a plastic jacket encapsulating the metal conductor.
