Embodiment Construction

[0030] figure 2 An optical fiber ribbon 10 according to the invention is shown. Fiber optic ribbon 10 (hereinafter simply referred to as ribbon) includes a plurality of optical waveguides, such as optical fibers 12, arranged in a generally flat configuration using a primary substrate 14 to form a tensile structure. For example, ribbon 10 may be used as a stand-alone fiber optic ribbon, part of a fiber optic ribbon stack, or a subgroup of fiber optic ribbons. Primary matrix 14 generally contacts optical fiber 12 and may encapsulate the optical fiber, thereby providing a robust structure for handling. The primary matrix 14 typically holds adjacent fibers together in a tensile configuration, thereby inhibiting relative movement between the fibers. The primary base 14 includes a first end 14a, a middle portion 14b and a second end 14c. In addition, the primary substrate 14 has a cross-section of non-uniform thickness.

[0031]In this embodiment, the first end portion 14a has a...

Abstract

A fiber optic ribbon having a predetermined separation sequence includes a first subset having a plurality of optical fibers arranged in a generally flat configuration and connected by a first primary substrate. The first subset is part of the first ribbon unit. A second subgroup, the second subgroup has a plurality of optical fibers arranged in a generally flat configuration and connected by a second primary substrate. The second subset is part of a second ribbon unit comprising a plurality of subsets. The secondary base connects the first fiber optic ribbon unit and the second fiber optic ribbon unit. The secondary matrix has a preferential pull portion adjacent to a ribbon unit interface defined between the first ribbon unit and the second ribbon unit.

Description

[0001] related application [0002] This application is a continuation (CIP) of US Patent Application 10 / 159,730, filed May 31, 2002, the disclosure of which is incorporated herein by reference. technical field [0003] The present invention relates generally to optical fiber ribbons, and more particularly to optical fiber ribbons having a preferential separation sequence for tearing the optical fiber ribbons. Background technique [0004] Fiber optic ribbons include optical waveguides, such as optical fibers, that transmit optical signals such as voice, video, and / or data information. Fiber optic cables using fiber optic ribbons can result in a relatively high fiber density. Fiber optic ribbon structures can generally be divided into two broad categories. That is, fiber optic ribbons with subunits and fiber optic ribbons without subunits. For example, a fiber optic ribbon having a subgroup structure includes at least one optical fiber surrounded by a primary substrate to...
