Abstract
Disclosed is a method accessing one or more optical fibers in a telecommunication cable in a way that considerably reduces the risk of damaging the optical fibers. To avoid inadvertent damage caused by a cutting tool, the method includes moving optical fibers and/or micromodules away from the area on the cable that is to be cut.
Claims19
A method for accessing one or more optical fibers of a telecommunication cable, comprising:
- providing a cable that includes (i) a cable jacket defining a central cable core and (ii) a plurality of optical fibers freely positioned within the central cable core;
- identifying a cutout area on the outer periphery of the cable jacket from which at least one access window is formed;
- pushing at least some of the optical fibers to a section of the central cable core that is away from the cutout area by exerting, upon at least some of the optical fibers at two or more longitudinally distant points, a force (F) having at least one radial component with respect to the cable;
- and
- performing a cutout in the cable jacket in the cutout area while substantially maintaining the force (F) upon at least some of the optical fibers to form at least one access window.

A method for accessing one or more optical fibers of a telecommunication cable, comprising:
- providing a cable that includes (i) a cable jacket defining a central cable core, (ii) a micromodule positioned within the central cable core, and (iii) one or more optical fibers positioned within the micromodule;
- delineating a cutout area on the cable jacket;
- displacing the micromodule away from the cutout area by exerting a displacement force upon the micromodule at two or more longitudinally distant points;
- and
- cutting an access window within the delineated cutout area and through the cable jacket while essentially maintaining a displacement force upon the micromodule.
