Abstract

Splitter housings suitable for a rapid deployment of an FTTX network system are disclosed. For some embodiments, a splitter housing splits one of many input optical fibers to a plurality of output optical fibers and keeps the rest of input optical fibers for future network expansion. For other embodiments, a splitter housing splits one of many input optical fibers to a plurality of output optical fibers and terminates the rest of input optical fibers at an output multi-fiber connector port. For network system embodiments, two or more splitter housings are optically connected in series to deploy a FTTX network system.

First claim

What is claimed is:

1 . A splitter housing for fiber-to-the-premises (FTTX) comprising:
an outside plant (OSP) rated housing; an OSP rated input multi-fiber connector port on the housing to receive a connectorized optical fiber cable with a plurality of input optical fibers; at least one splitter inside the housing, the splitter is optically connected to one of the input optical fibers, wherein the splitter splits the input optical fiber into a plurality of output optical fibers to serve multiple premises using a single optical fiber; and a plurality of OSP rated output connector ports, wherein each output connector port terminates at least one output optical fiber extending from the splitter; wherein the rest of input optical fibers not optically connected to the splitter are available for future network expansion.

2 . The splitter housing of claim 1 , wherein the splitter housing is pre-fabricated.

3 . The splitter housing of claim 1 , wherein the splitter splits the input optical fiber into n output optical fibers, wherein n is a natural number.

4 . The splitter housing of claim 3 , wherein n is 4, 8, 12, 16, 20 or 24.

5 . The splitter housing of claim 1 , wherein the splitter is a planar light circuit (PLC).

6 . The splitter housing of claim 1 , wherein the output connector ports are receptacles for receiving a connectorized drop cable that extends to a predetermined premise.

7 . The splitter housing of claim 1 , wherein the output connector ports are on the exterior surface of the housing.

8 . A splitter housing for fiber-to-the-premises (FTTX) comprising:
an outside plant (OSP) rated housing; an OSP rated input multi-fiber connector port on the housing to receive a connectorized optical fiber cable with a plurality of input optical fibers; at least one splitter inside the housing, the splitter is optically connected to one of the input optical fibers, wherein the splitter splits the input optical fiber into a plurality of output optical fibers to serve multiple premises using a single optical fiber; a plurality of OSP rated output connector ports, wherein each output connector port terminates at least one output optical fiber extending from the splitter; and an OSP rated output multi-fiber connector port on the housing to receive the rest of input optical fibers not optically connected to the splitter.

9 . The splitter housing of claim 8 , wherein the splitter housing is pre-fabricated.

10 . The splitter housing of claim 8 , wherein the splitter splits the input optical fiber into n output optical fibers, wherein n is a natural number.

11 . The splitter housing of claim 10 , wherein n is 4, 8, 12, 16, 20 or 24.

12 . The splitter housing of claim 8 , wherein the splitter is a planar light circuit (PLC).

13 . The splitter housing of claim 8 , wherein the output connector ports are receptacles for receiving a connectorized drop cable that extends to a predetermined premise.

14 . The splitter housing of claim 8 , wherein the output connector ports are on the exterior surface of the housing.

15 . A fiber-to-the-premises (FTTX) network system comprising:
a central office; a cable combiner optically connected to the central office; a first splitter housing optically connected to the cable combiner; and a second splitter housing optically connected to the first splitter housing, wherein the first and second splitter housings, each comprising:
an outside plant (OSP) rated housing;
an OSP rated input multi-fiber connector port on the housing to receive a connectorized optical fiber cable with a plurality of input optical fibers;
at least one splitter inside the housing, the splitter is optically connected to one of the input optical fibers, wherein the splitter splits the input optical fiber into a plurality of output optical fibers to serve multiple premises using a single optical fiber;
a plurality of OSP rated output connector ports, wherein each output connector port terminates at least one output optical fiber extending from the splitter; and
an OSP rated output multi-fiber connector port on the housing to receive the rest of input optical fibers not optically connected to the splitter; and
a connectorized multi-fiber optical fiber cable optically connects the OSP rated output multi-fiber connector port of the first splitter housing and the OSP rated input multi-fiber connector port of the second splitter housing.

16 . The fiber-to-the-premises (FTTX) network system of claim 15 , wherein the FTTX network system comprises a plurality of splitter housings and each splitter housing is optically connected to other splitter housings in series.

17 . The fiber-to-the-premises (FTTX) network system of claim 16 , wherein the splitter housings are optically connected in series until the last of the input optical fiber is optically connected to a splitter.
