US 4,305,642 A · Optical fiber transition device and assembly

Abstract

A transition device (10) is provided to facilitate the forming of a lightguide ribbon cable unit (22) from a plurality of individual insulated light conductors (24). The light conductors (24), which each include a light-conductive glass fiber (12) surrounded by an inner layer (14) of insulation and an outer layer (16) of insulation, are mounted into converging channels (44) of the transition device (10), such that portions of the glass fibers which have been stripped of insulation extend from an exit end (50) of the device arranged in a parallel side-by-side array between two strips of pressure-sensitive adhesive tapes (18 and 20) to form the ribbon cable unit (22). The assembled transition device (10), ribbon cable unit (22) and light conductors (24) produce an optical fiber assembly (93).

Dependent claims

A transition device for use in forming a fiber ribbon cable unit from a plurality of individual fibers, which comprises:

a support block;
a plurality of spaced elongated ribs formed in the support block and defining a plurality of fiber-receiving channels which converge toward one another from a spaced relationship at an entrance end of the block to a closely adjacent relationship substantially adjacent an exit end of the block;
and
converging inner wall sections formed in the support block and defining side walls of outermost ones of the converging channels defined by the elongated ribs, one of the inner wall sections extending to the exit end of the block to define a fiber ribbon support surface and the other of the inner wall sections terminating in spaced relationship from the exit end of the block to provide access to the fiber ribbon support surface.
