Abstract: Small-radius coated optical fibers having large mode field diameter and low bending losses. The coated fiber may have an outer radius of 110 μm or less, while providing a mode field diameter of 9.0 μm or greater and a bending loss when wrapped about a 15 mm mandrel of 0.5 dB/km or less at wavelength of 1550 nm. The coated fiber may have a mode field diameter of 9.2 μm or greater and may have a bending loss at 1550 nm of 0.25 dB/km or less when wrapped about a 20 mm mandrel or a bending loss at 1550 nm of 0.02 dB/km or less when wrapped about a 30 mm mandrel.

Abstract: An optical fiber having an ink layer that includes an optical brightener is described. The optical brightener is a marker that permits identification of the fiber. The ink layer may also include a pigment, where either or both of the pigment and optical brightener may function as a marker for identifying the fiber. Bundles of two or more optical fibers, each of which includes an ink layer containing an optical brightener, are also described.

Abstract: This disclosure is directed to lighting diffusing fibers (LDFs) having a flame retardant coating thereon. The LDFs comprise a glass RAL fiber core having a primary polymer coating of a clear, colorless polymeric material having an index of refraction less than that of the glass fiber core and a flame retardant coating applied over the primary coating. The flame retardant coating consist of approximately 35-85 wt. % UV curable polymer forming monomers and 15-65 wt. % of an inorganic, halogen free filler, along with at least one photoinitiator and an antioxidant. In an embodiment phosphor-containing polymer layer can be applied between the primary coating and the flame retardant coating. In another embodiment the phosphor can be added to the flame retardant coating.
