Embodiment Construction

[0020] The invention will be described more fully hereinafter with reference to the accompanying drawings, which show preferred embodiments of the invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; Ranges convey to those skilled in the art. The drawings are not necessarily drawn to scale, but rather in a form which clearly illustrates the invention.

[0021] figure 2 Shown in is an optical fiber ribbon 10 according to the present invention. For example, fiber optic ribbon 10 may be used as an isolated fiber optic ribbon, part of a fiber optic ribbon stack, or a subset of a larger fiber optic ribbon. The fiber optic ribbon 10 comprises two subgroups 13 connected by a secondary matrix 15 . The subgroup 13 includes a plurality of optical fibers 12 connected by a primary matrix 14 . The primary matrix 14 holds adjacent optical fibers together in a generally elongated configura...

Abstract

The fiber optic ribbon has a first subset and a second subset. The first and second subsets each include a plurality of optical fibers connected by respective primary substrates. The first and second subsets are generally aligned along a plane with the secondary substrate contacting portions of the first and second subsets. The secondary base has at least one end portion and at least one middle portion. At least one intermediate portion and at least one end portion of the secondary substrate are separated by a gap along at least a portion of the longitudinal axis thereby defining a preferential pull portion. In other embodiments, at least one intermediate portion is recessed relative to at least one end portion.

Description

technical field [0001] The present invention relates generally to fiber optic ribbons, and more particularly to fiber optic ribbons having a preferential tear portion for separating fiber optic ribbons into subgroups. Background technique [0002] 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 form a first subgroup, a second subgroup having a similar structure, both contacted and / or encapsulated by a secondary substrate. On the other hand, fiber optic ribbons without subgroups typicall...
