Patent number: 6171177Abstract: Midspan access to selected optical fibers which are encapsulated in an optical ribbon or tube is achieved by placing the desired span of the encapsulated fibers to be accessed between opposing abrasive layers and controllably urging at least one of the abrasive layers in the direction of the opposing abrasive layer to cause both abrasive layers to contact the encapsulant which covers the fibers. The amount of force applied to the at least one abrasive layer is limited by the structure of a resilient element which is coupled to the abrasive surface. Stress concentrators are created in the encapsulant and the encapsulant is removed from the span portion by relative movement of the encapsulated fibers and the abrasive layers. A minimum separation distance between the opposing abrasive layers can be defined, according to the thickness of the specific encapsulated fiber medium undergoing fiber separation, to avoid contact between the abrasive surfaces and the fibers within the medium.Type: GrantFiled: July 8, 1999Date of Patent: January 9, 2001Assignee: Pirelli Cable CorporationInventor: Jonathan G.
