Abstract

A fixture is for forming a fiber optic array that defines a plurality of discrete fibers extending from a spaced-apart arrangement to a consolidated arrangement wherein the fibers are layered next to each other for a further ribbonizing process. The fixture includes a pair of contact blades that are configured to slide along a direction transverse to the longitudinal axes of the fibers for consolidating the fibers.

First claim

What is claimed is:

1. A fiber optic array, comprising:
a plurality of optical fibers, each fiber including a buffer tube portion surrounding the fiber;
a one-piece substrate for supporting the plurality of optical fibers, the substrate defining a first end and a second end and a first outer edge and a second outer edge perpendicular to the first and second ends, the one-piece substrate configured to be placed within a fiber optic cassette; and
a plurality of spaced-apart channels formed integrally with the one-piece substrate as a unitary structure defining straight parallel portions at the first end of the substrate and a fiber clamp provided at the second end of the substrate, the spaced-apart channels provided in a stacked arrangement extending from the first outer edge to the second outer edge, the spaced-apart channels also defining curved rear portions for transitioning the optical fibers from the straight parallel portions inwardly away from the first and second outer edges toward a central portion of the substrate where the fiber clamp is provided with minimum bend radius protection, wherein the spaced-apart channels define open top ends for receiving the optical fibers therein such that the straight parallel portions of the channels defined at the first end of the substrate are sized to frictionally receive and secure the buffer tube portions of the optical fibers without an additional structure covering top sides of the optical fibers, wherein the substrate is configured such that the fibers at the channels extend outwardly from the channels to an exterior of the substrate to form pigtails that are terminated with fiber optic ferrules, wherein the substrate is configured to position the fibers therein such that the entirety of each of the fiber optic ferrules extends out past the first end of the substrate;
wherein the plurality of optical fibers are positioned on the one-piece substrate such that the fibers extend from being spaced-apart via the channels to a consolidated arrangement at the central portion wherein the fibers are layered next to each other, the fiber clamp securing the consolidated fibers at the second end of the substrate, and wherein the plurality of optical fibers are positioned within the spaced-apart channels such that a majority of each optical fiber is uncovered along a length thereof as the optical fibers extend from the first end to the second end of the one-piece substrate.

2. A fiber optic array according to claim 1 , wherein the fiber clamp is defined by a clip that is snap-fit interlocked to the substrate.

3. A fiber optic array according to claim 1 , wherein the fibers supported by the substrate are further secured to the substrate via at least one piece of adhesive tape.
