Abstract

A fiber optic multiport includes a housing, a multi-fiber connector coupled to the housing, a plurality of optical fibers, extensions, and ports connected to distal ends of the extensions. The housing defines an enclosure and may seal off the enclosure from the environment. The plurality of optical fibers are connected to and extend from the multi-fiber connector into the enclosure. The extensions have proximal ends attached to the housing and the extensions project away from the housing. The extensions support sub-sets of the plurality of optical fibers, and the extensions are flexible such that the extensions may bend independently of one another.

Claims

1. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure;

a plurality of optical fibers extending into the enclosure;

extensions having a proximal end attached to the housing, the extensions projecting away from a face of the housing, wherein the extensions support sub-sets of the plurality of optical fibers; and

ports connected to distal ends of the extensions, wherein an area of the face of the housing is less than a net area of forward end-faces of the ports.

2. The multiport of claim 1, wherein the net area of forward end-faces of the ports is at least twice the area of the face of the housing.

3. The multiport of claim 1, wherein the ports are attached to the housing by way of the extensions, which are flexible such that the extensions may bend independently of one another.

4. The multiport of claim 1, further including a connector positioned on an extension.

5. The multiport of claim 1, further including a connector coupled to the housing.

6. The multiport of claim 1, wherein the housing comprises interlocking structure that seals off the enclosure from the environment.

7. The multiport of claim 1, wherein the enclosure is filled with a potting material.

8. The multiport of claim 1, wherein the housing further comprises an extension organizer.

9. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure with a face;

a plurality of optical fibers extending into the enclosure,

one or more guides in the enclosure, wherein slack of the plurality of optical fibers is routed by the one or more guides;

extensions having a proximal end attached to the housing, the extensions projecting away from the housing from the face, wherein the extensions support sub-sets of the plurality of optical fibers, and wherein the extensions are flexible such that the extensions may bend independently of one another; and

ports connected to distal ends of the extensions, wherein an area of the face of the housing is less than a net area of forward end-faces of the ports.

10. The multiport of claim 9, wherein the net area of forward end-faces of the ports is at least twice the area of the face of the housing.

11. The multiport of claim 9, further including a connector positioned on an extension.

12. The multiport of claim 9, further including a connector coupled to the housing.

13. The multiport of claim 9, wherein the housing comprises interlocking structure that seals off the enclosure from the environment.

14. The multiport of claim 9, wherein the enclosure is filled with a potting material.

15. The multiport of claim 9, wherein the housing further comprises an extension organizer.

16. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure, and wherein the housing comprises interlocking structure that seals off the enclosure from the environment;

a connector;

a plurality of optical fibers disposed within the enclosure;

extensions having proximal ends attached to the housing, the extensions projecting away from the housing, wherein the extensions support sub-sets of the plurality of optical fibers, and wherein the extensions are flexible such that the extensions may bend independently of one another; and

ports connected to distal ends of the extensions.

17. The multiport of claim 16, wherein the housing has a face from which the extensions project, and wherein the area of the face is less than the net area of forward end-faces of the sets of ports.

18. The multiport of claim 17, wherein the net area of forward end-faces of the sets of ports is at least twice the area of the face of the housing.

19. The multiport of claim 16, wherein the connector positioned on an extension.

20. The multiport of claim 16, wherein the connector coupled to the housing.

21. The multiport of claim 16, wherein the enclosure is filled with a potting material.

22. The multiport of claim 16, wherein the housing further comprises an extension organizer.

23. The multiport of claim 16, wherein the connector is integrated with the housing by way of a flange interfacing a groove, the flange and groove extending around the connector and along an interior edge of the housing such that the interface of the flange and groove seals the integration of the connector with the housing and axially secures the connector, and wherein the flange and groove are adjoined by a pin and slot that orient the multi-fiber connector and limit rotation relative to the housing.

24. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure and a face, and wherein the housing comprises interlocking structure that seals off the enclosure from the environment;

a plurality of optical fibers extending into the enclosure;

extensions having proximal ends attached to the housing, the extensions projecting away from the housing, wherein the extensions support sub-sets of the plurality of optical fibers, and wherein the extensions are flexible such that the extensions may bend independently of one another, wherein the multiport comprises at least two groups of the extensions, wherein extensions within each group are the same length as one another, and wherein lengths of extensions differ between the two groups, whereby sets of ports corresponding to the two groups of extensions are staggered relative to one another from the housing; and

ports connected to distal ends of the extensions, wherein ports within each set are coupled to one another with a collar, wherein the extensions project from the face of the housing, and wherein an area of the face is less than a net area of forward end-faces of the sets of ports.

25. The multiport of claim 24, wherein at least two of the extensions are the same lengths as one another.

26. The multiport of claim 24, wherein the net area of forward end-faces of the sets of ports is at least twice the area of the face of the housing.
