The optimal design of tightly jacketed double-coated optical fibers to minimize the mechanical strip force is investigated. The stripper is assumed to consist of two hinged arms and paired blades with semicircular bore. It is found that the strip force is a function of the bore radius of the stripper. The optimal bore radius of the stripper is equal to the radius of the primary coating. Based on the type of strip force, the stripping process can be divided into three steps. In the first stripping step, a strip force Ft is required to extend the crack on the cutting plane to the glass fiber surface. In the second stripping process, a strip force Fb is required to break all of the adhesive bonds at the interface of the glass fiber and primary coating. In the third step, a strip force Ff is required to push the polymeric coating tube off the glass fiber. For commercial tightly jacketed double-coated optical fibers, Fb is much larger than Ft and Ff . The strip force Fb could be minimized by a suitable selection of polymeric coatings and their thicknesses.
