Abstract

The present disclosure relates to systems and method for deploying a fiber optic network. Distribution devices are used to index fibers within the system to ensure that live fibers are provided at output locations throughout the system. In an example, fibers can be indexed in multiple directions within the system. In an example, fibers can be stored and deployed form storage spools.

First claim

What is claimed is:

1. A distributed optical network comprising:
an indexing terminal including a housing defining a first output port and a second output port;
optical fibers extending between first ends and second ends, the first ends of the optical fibers being terminated by a first multi-fiber optical connector, the second end of a first of the optical fibers being received at the first output port, the second ends of a plurality of the optical fibers being received at the second output port and terminated by a second multi-fiber optical connector disposed thereat, the plurality of the optical fibers being indexed between the first multi-fiber optical connector and the second multi-fiber optical connector so that the second multi-fiber optical connector has at least one fiber position that does not receive the second end of any optical fiber extending from the first multi-fiber optical connector; and
a multi-service terminal disposed external of the indexing terminal, the multi-service terminal having an input that is configured to optically couple with the first output port of the indexing terminal, the multi-service terminal including an optical splitter that receives optical signals provided to the input of the multi-service terminal, the multi-service terminal also including a plurality of splitter pigtails routed from the optical splitter to distribution ports.

2. The distributed optical network of claim 1 , wherein the first multi-fiber optical connector is held by the housing of the indexing terminal.

3. The distributed optical network of claim 1 , wherein the first multi-fiber optical connector is spaced from the housing of the indexing terminal to terminate a stub input cable extending outwardly from the housing.

4. The distributed optical network of claim 1 , wherein the input of the multi-service terminal includes a stub cable.

5. The distributed optical network of claim 1 , wherein the input of the multi-service terminal includes an input port defined by a housing of the multi-service terminal.

6. The distributed optical network of claim 1 , further comprising a mounting bracket to secure the indexing terminal to a mounting structure.

7. The distributed optical network of claim 6 , further comprising a payout spool removably coupled to the mounting bracket.

8. The distributed optical network of claim 6 , wherein the multi-service terminal and the indexing terminal are both mounted to the mounting bracket prior to deployment.

9. The distributed optical network of claim 1 , wherein the multi-service terminal includes a plurality of optical power splitters.

10. The distributed optical network of claim 1 , wherein the first and second output ports are hardened.
