Abstract
The present invention relates to an optical fiber ribbon. The optical fiber ribbon includes a plurality of coated, substantially coplanar optical fibers and a ribbon matrix material which maintains the plurality of coated optical fibers in substantially coplanar alignment. Each of the optical fibers includes a glass core, a cladding layer. surrounding and adjacent to the glass core, and a primary polymeric coating material, preferably containing a silicone, surrounding and adjacent to the cladding layer. The primary polymeric coating material adheres to the cladding layer to form a cladding layer-primary polymeric coating material interface. Upon application of a longitudinal stripping force at the cladding layer-primary polymeric coating material interface, the ribbon matrix material and the primary polymeric coating material are substantially removed from the cladding layer. A continuous, smooth residual layer of the primary polymeric coating material with a thickness of less than about 5 &mgr;m remains on the cladding layer. These optical fiber ribbons exhibit enhanced strippability without sacrificing adhesion of the primary coating material and are well-suited to being spliced by mass fusion splicing techniques.
