Abstract

The present disclosure relates to a telecommunications connection device. The device including a housing, a plurality of single-fiber connectorized pigtails that extend outwardly from the housing and a multi-fiber connectorized pigtail that extends outwardly from the housing. The multi-fiber connectorized pigtail can be optically coupled with the single fiber connectorized pigtails. The device can include optical fibers routed from the multi-fiber connectorized pigtail through the housing to the single-fiber connectorized pigtails. The single-fiber connectorized pigtails can be more flexible than the multi-fiber connectorized pigtail.

First claim

What is claimed is:

1. A telecommunications connection device comprising:
a first ruggedized multi-fiber connector;
a plurality of second ruggedized multi-fiber connectors;
a multi-fiber cable including a plurality of optical fibers, the multi-fiber cable being terminated by the first ruggedized multi-fiber connector, the multi-fiber cable having a flat configuration, the multi-fiber cable having two imbedded strength members, the strength members including fiber reinforced epoxy rods;
a plurality of multi-fiber pigtails, each multi-fiber pigtail including fewer optical fibers than the multi-fiber cable, each multi-fiber pigtail including at least two optical fibers, each of the multi-fiber pigtails being longer than the multi-fiber cable, each of the multi-fiber pigtails being terminated by one of the second ruggedized multi-fiber connectors; and
a breakout housing at which the multi-fiber cable transitions to the multi-fiber pigtails.

2. The telecommunications connection device of claim 1 , wherein each of the multi-fiber pigtails includes a jacket containing two optical fibers.

3. The telecommunications connection device of claim 2 , wherein each of the multi-fiber pigtails includes cable strength members that are anchored to the housing.

4. The telecommunications connection device of claim 3 , wherein the cable strength members of the multi-fiber pigtails include Aramid yarn.

5. The telecommunications connection device of claim 1 , wherein each of the multi-fiber pigtails includes a buffer layer surrounding the optical fibers.

6. The telecommunications connection device of claim 1 , wherein each of the second ruggedized multi-fiber connectors includes two optical ferrules.

7. The telecommunications connection device of claim 6 , wherein the second ruggedized multi-fiber connectors include ODC connectors.

8. The telecommunications connection device of claim 1 , wherein the housing has a flexible construction.

9. The telecommunications connection device of claim 1 , wherein the housing has a rigid construction.

10. The telecommunications connection device of claim 1 , wherein the optical fibers of the multi-fiber pigtails are optically coupled to the optical fibers of the multi-fiber cable at a mass-fusion splice.

11. The telecommunications connection device of claim 1 , wherein the plurality of multi-fiber pigtails includes six multi-fiber pigtails.

12. The telecommunications connection device of claim 1 , wherein the strength members are anchored to the housing.

13. The telecommunications connection device of claim 1 , wherein the optical fibers of the multi-fiber cable are ribbonized.

14. The telecommunications connection device of claim 1 , wherein the first multi-fiber connector includes a robust fastener that is used to fasten the first ruggedized multi-fiber connector within a corresponding ruggedized port or to a mating ruggedized connector.

15. The telecommunications connection device of claim 14 , wherein the robust fastener includes a threaded coupler.

16. The telecommunications connection device of claim 14 , wherein the robust fastener includes a bayonet-style coupler.

17. The telecommunications connection device of claim 1 , wherein each of the second multi-fiber connectors includes a robust coupling element.

18. A telecommunications connection device comprising:
a first ruggedized multi-fiber connector;
a plurality of second ruggedized multi-fiber connectors;
a multi-fiber cable including a plurality of optical fibers, the multi-fiber cable being terminated by the first ruggedized multi-fiber connector;
a plurality of multi-fiber pigtails, each multi-fiber pigtail including fewer optical fibers than the multi-fiber cable, each multi-fiber pigtail including at least two optical fibers, each of the multi-fiber pigtails being longer than the multi-fiber cable, each of the multi-fiber pigtails being terminated by one of the second ruggedized multi-fiber connectors; and
a breakout housing at which the multi-fiber cable transitions to the multi-fiber pigtails, wherein the housing has a flexible construction.

19. A telecommunications connection device comprising: a first ruggedized multi-fiber connector; a plurality of second ruggedized multi-fiber connectors; a multi-fiber cable including a plurality of optical fibers, the multi-fiber cable being terminated by the first ruggedized multi-fiber connector; a plurality of multi-fiber pigtails, each multi-fiber pigtail including fewer optical fibers than the multi-fiber cable, each multi-fiber pigtail including at least two optical fibers, each of the multi-fiber pigtails being longer than the multi-fiber cable, each of the multi-fiber pigtails being terminated by one of the second ruggedized multi-fiber connectors, the optical fibers of the multi-fiber pigtails being optically coupled to the optical fibers of the multi-fiber cable at a mass-fusion splice; and a breakout housing at which the multi-fiber cable transitions to the multi-fiber pigtails.
