ABSTRACT:
A visually-distinguishable fiber pair in a shared coating, a method for making uncoated visually-distinguishable fiber, and a fiber-optic system using a visually-distinguishable fiber and a dark fiber in a shared coating are disclosed. To form the visually-distinguishable fiber, a marker is incorporated onto or into uncoated optical fiber. The marker can be applied to the cladding of the fiber, to a buffer layer disposed on the cladding layer, or integrated in a boule from which an optical fiber is drawn. In a further aspect, a marked fiber is paired with an unmarked fiber or a differently-marked fiber creating a visually-distinguishable fiber pair. The distinguishable paired fibers are then coated with plastic.
