Abstract

The present disclosure relates to a fiber optic network architecture that uses a factory manufactured break-out cable as a backbone for supporting a chain or chains of indexing optical components that branch outwardly from the factory manufactured break-out cable so as to extend the reach of a fiber optic network.

First claim

What is claimed is:

1. A system for building an architecture for a fiber optic network, the system comprising:
a factory manufactured fiber optic break-out cable including a main fiber distribution cable and a plurality of factory integrated mid-span access locations positioned along the length of the main fiber distribution cable, the mid-span access locations including demateable fiber optic connection locations; and
a plurality of indexing components adapted to be daisy chained together to form a chain of indexing components and adapted to be optically coupled to one or more of the demateable fiber optic connection locations at one or more of the mid-span access locations of the factory manufactured fiber optic break-out cable;
wherein the demateable fiber optic connection locations of the factory manufactured fiber optic break-out cable include a multi-fiber demateable fiber optic connection location, and wherein the indexing components each include:
a first multi-fiber demateable fiber optic connection location optically coupled to a demateable fiber optic connection location of a mid-span access location, the first multi-fiber demateable fiber optic connection location including a first plurality of sequential fiber positions;
a second multi-fiber demateable fiber optic connection location including a second plurality of sequential fiber positions;
a plurality of indexing fibers indexed between the first plurality of sequential fiber positions and the second plurality of sequential fiber positions;
at least one of the sequential fiber positions of the first plurality of sequential fiber positions being optically coupled to a forward drop location of the indexing component, the forward drop location including a demateable fiber optic connection interface; and
at least one of the sequential fiber positions of the second plurality of sequential fiber positions being optically coupled to a reverse drop location of the indexing component, the reverse drop location including a demateable fiber optic connection interface.

2. The system of claim 1 , wherein the first multi-fiber demateable fiber optic connection location is adapted to be directly connected to the demateable fiber optic connection location of the mid-span access location.

3. The system of claim 1 , further comprising a passive optical splitter component for optically coupling the first multi-fiber demateable fiber optic connection location to the demateable fiber optic connection location of the mid-span access location.

4. The system of claim 1 , further comprising a multi-fiber fan-out component for optically coupling the first multi-fiber demateable fiber optic connection location to the demateable fiber optic connection location of the mid-span access location.

5. The system of claim 1 , further comprising a multi-fiber patch cord for optically coupling the first multi-fiber demateable fiber optic connection location to the demateable fiber optic connection location of the mid-span access location.

6. A fiber optic network comprising:
a factory manufactured fiber optic break-out cable including a main fiber distribution cable and a plurality of factory integrated mid-span access locations positioned along the length of the main fiber distribution cable, the mid-span access locations including demateable fiber optic connection locations; and
a plurality of indexing components daisy chained together to form a chain of indexing components, the chain of indexing components having a first end optically coupled to one of the demateable fiber optic connection locations at one of the mid-span access locations of the factory manufactured fiber optic break-out cable;
wherein the demateable fiber optic connection locations of the factory manufactured fiber optic break-out cable include a multi-fiber demateable fiber optic connection location, and wherein the indexing components each include:
a first multi-fiber demateable fiber optic connection location optically coupled to a demateable fiber optic connection location of a mid-span access location, the first multi-fiber demateable fiber optic connection location including a first plurality of sequential fiber positions;
a second multi-fiber demateable fiber optic connection location including a second plurality of sequential fiber positions;
a plurality of indexing fibers indexed between the first plurality of sequential fiber positions and the second plurality of sequential fiber positions;
at least one of the sequential fiber positions of the first plurality of sequential fiber positions being optically coupled to a forward drop location of the indexing component, the forward drop location including a demateable fiber optic connection interface; and
at least one of the sequential fiber positions of the second plurality of sequential fiber positions being optically coupled to a reverse drop location of the indexing component, the reverse drop location including a demateable fiber optic connection interface.

7. The fiber optic network of claim 6 , wherein the first end of the chain of indexing components is optically connected directly to the demateable fiber optic connection location at one of the mid-span access locations of the factory manufactured break-out cable.

8. The fiber optic network of claim 6 , wherein the first end of the chain of indexing components is optically connected indirectly to the demateable fiber optic connection location at one of the mid-span access locations of the factory manufactured break-out cable.

9. The fiber optic network of claim 8 , wherein the first end of the chain of indexing components is optically connected indirectly to the demateable fiber optic connection location at one of the mid-span access locations of the factory manufactured break-out cable by an optical splitting component.

10. The fiber optic network of claim 8 , wherein the first end of the chain of indexing components is optically connected indirectly to the demateable fiber optic connection location at one of the mid-span access locations of the factory manufactured break-out cable by a patch cord.

11. The fiber optic network of claim 8 , wherein the first end of the chain of indexing components is optically connected indirectly to the demateable fiber optic connection location at one of the mid-span access locations of the factory manufactured break-out cable by a fan-out component.

12. The fiber optic network of claim 6 , wherein a second end of the chain of indexing components is optically connected to another one of the demateable fiber optic connection locations at another one of the mid-span access locations of the factory manufactured break-out cable.

13. The fiber optic network of claim 6 , wherein a second end of the chain of indexing components is optically connected to a demateable fiber optic connection location at a mid-span access location of another factory manufactured break-out cable.

14. The fiber optic network of claim 6 , wherein the indexing components include passive optical splitters.

15. The fiber optic network of claim 6 , wherein the chain of indexing components supports a distributed split architecture.
