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 includes interlocking structure that seals 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, and wherein the housing comprises interlocking structure that seals off the enclosure from the environment;

a multi-fiber connector coupled to the housing;

a plurality of optical fibers connected to and extending from the multi-fiber connector 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; and

ports connected to distal ends of the extensions.

2. The multiport of claim 1, wherein at least two of the extensions are the same lengths as one another.

3. The multiport of claim 2, wherein at least two of the extensions are different lengths from one another.

4. The multiport of claim 3, 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.

5. The multiport of claim 4, wherein the multiport comprises three groups of extensions with four extensions in each group such that the multiport comprises twelve ports that are arranged in three staggered sets.

6. The multiport of claim 4, wherein ports within each set are coupled to one another with a collar.

7. The multiport of claim 6, 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.

8. The multiport of claim 1, wherein the enclosure comprises guides and wherein slack of the plurality of optical fibers is routed by the guides.

9. The multiport of claim 8, wherein the guides comprise round features over which the slack is routed to control bending of the slack.

10. The multiport of claim 8, wherein the slack comprises a length of optical fiber that is at least 50 millimeters.

11. The multiport of claim 8, wherein one or more of the optical fibers continuously extends between the multi-fiber connector and a respective one of the ports without splicing therebetween.

12. The multiport of claim 1, wherein the interlocking structure of the housing comprises pieces that define walls of the enclosure, and wherein edges of the pieces are mortised together to seal the enclosure.

13. The multiport of claim 1, wherein the multi-fiber connector is integrated with the housing by way of a flange interfacing a groove, the flange and groove extending around the multi-fiber connector and along an interior edge of the housing such that the interface of the flange and groove seals the integration of the multi-fiber connector with the housing and axially secures the multi-fiber 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.

14. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure;

a multi-fiber connector coupled to the housing;

a plurality of optical fibers connected to and extending from the multi-fiber connector 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 the area of the face of the housing is less than the net area of forward end-faces of the ports.

15. The multiport of claim 14, wherein the multi-fiber connector is rigidly fixed directly to the housing and 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.

16. The multiport of claim 14, wherein the housing comprises interlocking structure that seals off the enclosures from the environment, wherein the multi-fiber connector is integrated with the housing by way of a flange interfacing a groove, the flange and groove extending around the multi-fiber connector and along an interior edge of the housing such that the interface of the flange and groove seals the integration of the multi-fiber connector with the housing and axially secures the multi-fiber connector, and wherein the flange and groove are adjoined by a pin and slot that orient that multi-fiber connector and limit rotation relative to the housing.

17. The multiport of claim 16, wherein the interlocking structure of the housing comprises pieces that define walls of the enclosure, wherein edges of the pieces are mortised together to seal the enclosure.

18. A fiber optic multiport, comprising:

a housing, wherein the housing defines an enclosure;

a multi-fiber connector integrated with the housing;

a plurality of optical fibers connected to and extending from the multi-fiber connector 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, 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.

19. The multiport of claim 18, wherein the one or more guides comprise one or more round features over which the slack is routed, and wherein the slack comprises a length of optical fiber that is at least 50 millimeters.

20. The multiport of claim 19, wherein one or more of the optical fibers continuously extends between the multi-fiber connector and a respective one of the ports without splicing therebetween.
