    摘要： A coated fiber strand includes one or more coating layers located directly or indirectly on the strand and at least one heterogeneous region present in or on one or more of the coating layer(s). The heterogeneous region(s) preferably comprises a material useful for coding of the fiber. One particularly preferred embodiment relates to an optical fiber having a primary coating layer and a secondary coating layer where the heterogeneous region(s) defines one or more colored stripes in or on the secondary coating layer. A method for forming a coated fiber, such as an optical fiber, includes introducing at least one coating layer onto a fiber strand such that one or more coating layers directly or indirectly cover at least a portion of the surface of the strand. The method further includes introducing at least one heterogeneous region into or onto a coating layer(s). The fiber can then be treated, e.g., cured so as to provide a desired product. By this method, a desired functionality, e.g., coding, can be introduced onto a fiber without adversely effecting subsequent processing steps, e.g., curing of the coating layer(s).

    摘要： A coating system for individual glass fibers of a lightwave communications system has improved strippability, particularly in situations where a group of such fibers are arrayed together in what is known as a ribbon. A preferred embodiment includes two layers (primary and secondary) of polymeric materials surrounding the glass fiber. The primary layer comprises an oligomer (50-80% by weight), a diluent (15-40% by weight), and additives (5-35% by weight). The oligomer comprises polyol "A," diisocyanate "B," and a hydroxy-terminated alkyl acrylate "C" having the structure C-B-A-B-C. At least one of the additives contains a non-crosslinked hydrocarbon component (1-20% by weight) having a structure R.sub.1 --(R).sub.n --R.sub.2 ; where R.sub.1, R.sub.2 comprises an alkyl group or an OH group, and R is a combination of C, H or C, H, O. In an alternative embodiment, the need for a diluent is substantially eliminated by using an oligomer having the structure E-D-E where "D" represents a carboxy-terminated polyol, and "E" represents a glycidyl acrylate.

    摘要： A drawn optical fiber (21) is provided with inner and outer layers (42,44) of coating material to protect the optical fiber during handling and use. The coating materials are such that they are characterized by being curable upon exposure to different portions of the light spectrum. In a preferred embodiment, the coating material of the inner layer includes a photoinitiator which absorbs light in the visible portion of the light spectrum whereas the outer coating material of the outer layer includes a photoinitiator which absorbs light in the ultraviolet light portion of the light spectrum.
