摘要： The system and methods for marking an optical fiber with color-coded marks disclosed herein include forming closely spaced multiple ink streams, with at least two of the ink streams having different colors. The optical fiber moves over a fiber path that resides adjacent the ink streams. The fiber path and the ink streams are made to briefly intersect so that the ink streams form on the outer surface of the optical fiber a group of spaced apart individual marks, wherein the group of individual marks constitute a color-coded mark. Repeating this marking process at different times as the fiber moves over the fiber path forms spaced apart color-coded marks along the length of the fiber. Subsequent drying and overcoating of the marks fixes and protects the color-coded marks.

摘要： A method for preparing optical fibers formed with high-particle-coated porous polymeric outer coating layer is provided. The method includes preparing a coating suspension solution by dispersing a plurality of particles into an organic solvent system, immersing one or more optical fibers into the coating suspension solution, removing the one or more optical fibers from the coating suspension solution to form high-particle-coated porous polymeric outer coating layer after drying. Concentrations and compositions of the particles in the coating suspension solution, concentrations and compositions of the organic solvent system, the period of time of immersing, or the external environment are adjusted such that the optical fibers is formed with high-particle-coated polymeric outer coating layers having desirable coating masses, coating thicknesses, or coating morphologies.

摘要： Described herein is a method for coating optical fiber where the coating has been cured by application of a source of monochromatic actinic radiation, such as a light emitting diode, wherein the coating contains a urethane(meth)acrylate oligomer; a (meth)acrylate diluent monomer; a diluent monomer having an electron donating group adjacent to the vinyl group, such as a vinyl ether monomer; and a photoinitiator. Also described are compositions which are capable of undergoing photopolymerization when coated on an optical fiber and when irradiated by a light emitting diode (LED) with improved surface cure and reduced yellowing. Also described are the coated optical fibers produced by such processes and compositions.

摘要： The present invention is directed to water-swellable, radiation curable compositions suitable for use in coating water-blocking fibers, such as optical fibers. The present invention is further directed to fibers, including optical fibers, which are coated with water-swellable exterior coatings that are configured to buckle and detach from the associated fiber to facilitate superior performance in longitudinal water-blocking testing. Also claimed and described are methods of applying such water-swellable coatings to optical fiber coatings. Further claimed and described are buffered bundles of fibers including at least one optical fiber that is coated with a water-swellable, radiation curable coating to ensure superior longitudinal water blocking performance.
