Abstract

A fiber optic cable assembly includes a fiber optic cable and a fiber optic connector. The cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis. Strength components of the cable are anchored to the connector. The fiber optic connector includes a multi-fiber ferrule defining a major axis that is generally perpendicular to the major axis of the jacket and a minor axis that is generally perpendicular to the minor axis of the jacket. Certain types of connectors include a connector body defining a side opening that extends along a length of the connector body; a multi-fiber ferrule configured for lateral insertion into the connector body through the side opening; and a cover that mounts over the side opening after the multi-fiber ferrule has been inserted into the connector body through the side opening.

Claims (24)

1. A fiber optic ruggedized connector and cable assembly comprising:

a connector body having a length that extends along an axis of the connector body, the connector body defining a side opening that extends along the length of the connector body;

a ferrule positioned at least partially within the connector body, the ferrule supporting at least one optical fiber of a fiber optic cable, and the ferrule being configured to mount into the connector body through the side opening; and

a fastener that mounts over the connector body, the fastener configured to rotate at least partially relative to the connector body, the fastener being configured to couple the fiber optic ruggedized connector to a ruggedized fiber optic adapter or another fiber optic ruggedized connector;

the connector body receiving and retaining at least one strength member of the fiber optic cable.

2. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the at least one optical fiber includes a first portion secured within the ferrule.

3. The fiber optic ruggedized connector and cable assembly of claim 2 , further comprising a cover that mounts over the side opening after the ferrule has been inserted into the connector body through the side opening.

4. The fiber optic ruggedized connector and cable assembly of claim 3 , further comprising a spring that biases the ferrule in a forward direction.

5. The fiber optic ruggedized connector and cable assembly claim 4 , wherein the cover includes a spring compression member that axially compresses the spring within the connector body when the cover is mounted to the connector body.

6. The fiber optic ruggedized connector and cable assembly of claim 2 , wherein the at least one optical fiber includes a second portion that extends rearwardly from the ferrule.

7. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the side opening extends along the length of the connector body for at least 50 percent of the length of the connector body.

8. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the side opening extends along the length of the connector body for at least 75 percent of the length of the connector body.

9. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the connector body is configured to receive and retain at least two strength members of the fiber optic cable.

10. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the fiber optic cable is a flat drop cable.

11. The fiber optic ruggedized connector and cable assembly of claim 2 , wherein a front end of the connector body is defined by a front end plate, wherein the front end plate defines a through-opening through which a portion of the ferrule extends.

12. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the fiber optic cable includes a jacket having an elongated transverse cross-sectional profile that defines a major axis and a minor axis, the major and minor axes of the jacket being generally perpendicular relative to one another.

13. The fiber optic ruggedized connector and cable assembly of claim 12 , wherein the ferrule defines a major axis and a minor axis, the major and minor axes of the ferrule being generally perpendicular relative to one another.

14. The fiber optic ruggedized connector and cable assembly of claim 13 , wherein the major axis of the ferrule is generally perpendicular to the major axis of the jacket and the minor axis of the ferrule is generally perpendicular to the minor axis of the jacket.

15. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the ferrule comprises a multi-fiber ferrule, and wherein end portions of a plurality of optical fibers are secured within the multi-fiber ferrule.

16. The fiber optic ruggedized connector and cable assembly of claim 15 , wherein the end portions of the plurality of optical fibers are spliced to optical fibers of the fiber optical cable at an optical splice location positioned within the connector body.

17. The fiber optic ruggedized connector and cable assembly of claim 16 , wherein the plurality of optical fibers are ribbonized, and wherein the splice location is reinforced and protected by a re-coating layer provided over the splice location.

18. The fiber optic ruggedized connector and cable assembly of claim 1 , further comprising an outermost sleeve that mounts over a metal reinforcing sleeve, the metal reinforcing sleeve being configured to mount over a rear portion of the connector body.

19. The fiber optic ruggedized connector and cable assembly of claim 1 , wherein the fastener comprises a threaded nut.

20. The fiber optic ruggedized connector and cable assembly of claim 1 , further comprising an environmental seal positioned about the connector body.
