Abstract
A connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes an optical fiber bundle including a plurality of optical fibers, at least one strength member, and a jacket surrounding the optical fiber bundle and the strength member. The connector assembly includes a rigid portion and defines a fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the fiber passage. The plurality of optical fibers undergo a transition from a ribbonized configuration to a loose, non-ribbonized configuration in the rigid portion of the connector assembly.

(canceled)
A connectorized fiber optic cabling assembly comprising:
- a fiber optic cable including:
- a plurality of optical fibers having at least a first fiber section and a second fiber section, the first fiber section being different than the second fiber section;
- a strength layer at least partially surrounding the plurality of optical fibers;
- and
- a jacket surrounding the strength layer and the plurality of optical fibers, at least some the plurality of optical fibers being moveable with respect to one another within the jacket and configured to contact the strength layer;
- and
- a connector assembly mounted on a first end of the fiber optic cable, the connector assembly including:
- a connector housing having a front end and a rear end, the rear end being substantially rigid;
- a multi-fiber ferrule biased at the front end of the connector housing, the multi-fiber ferrule defining a plurality of fiber holes, the fiber bundle secured at the multi-fiber ferrule and each of the plurality of optical fibers being inserted within a corresponding fiber hole of the plurality of fiber holes so as to terminate at a front face of the multi-fiber ferrule, wherein the multi-fiber ferrule defines the first fiber section of the plurality of optical fibers;
- a crimp sleeve, at least a portion of the strength layer and the jacket are captured between the rear end of the connector housing and the crimp sleeve, with the crimp sleeve crimped in place;
- and
- a strain relief boot having a front section and a rear section, the front section secured to the rear end of the connector housing at least partially covering the crimp sleeve, the rear section at least partially covering the jacket of the fiber optic cable.
A connectorized fiber optic cabling assembly comprising:
- a fiber optic cable including:
- a plurality of optical fibers;
- a plurality of strength yarns;
- and
- a jacket surrounding the plurality of optical fibers and the plurality of strength yarns, at least some of the plurality of optical fibers being moveable with respect to one another within the jacket and configured to contact at least some of the plurality of strength yarns;
- and
- a connector assembly mounted on a first end of the fiber optic cable, the connector assembly including:
- a connector housing having a front end and a rear end, the rear end defining an outer surface section;
- a multi-fiber ferrule biased at the front end of the connector housing, the multi-fiber ferrule defining a plurality of fiber holes, the plurality of optical fibers secured at the multi-fiber ferrule and each of the plurality of optical fibers being inserted within a corresponding fiber hole of the plurality of fiber holes so as to terminate at a front face of the multi-fiber ferrule, wherein the plurality of optical fibers are ribbonized at least at the multi-fiber ferrule;
- a compression fastener disposed outside of the outer surface section of the rear end of the connector housing, at least a portion of the plurality of strength yarns and the jacket are captured between the outer surface section and inside the compression fastener, with the compression fastener securing both the plurality of strength yarns and the jacket to the connector housing;
- and
- a strain relief boot having a front section and a rear section, the front section defining a front opening, the strain relief boot secured to the rear end of the connector housing by the front opening engaging with the compression fastener, the rear section at least partially covering the jacket of the fiber optic cable.
A connector assembly for a fiber optic cable, the fiber optic cable including a plurality of optical fibers, a plurality of strength yarns, and a jacket, at least some of the plurality of optical fibers being moveable with respect to one another within the jacket and configured to contact at least some of the plurality of strength yarns, the connector assembly comprising:
- a connector housing having a front end and a rear end, a fiber passage defined by the connector housing and extending between the front end and the rear end, the rear end comprising an outer section having a plurality of ribs;
- a multi-fiber ferrule defining a plurality of fiber holes and at least one pin hole, each of the plurality of fiber holes and the at least one pin hole extending longitudinally through the multi-fiber ferrule, at least some of the plurality of fiber holes arranged on a common plane and spaced apart from one another;
- a ferrule boot disposed at a rear end of the multi-fiber ferrule and configured to surround at least a portion of the plurality of optical fibers;
- a spring disposed within the connector housing and rearward of the multi-fiber ferrule so as to bias the multi-fiber ferrule towards the front end, the spring configured to surround at least a portion of the plurality of optical fibers;
- a pin retainer disposed between the rear end of the multi-fiber ferrule and the spring, the pin retainer supporting at least one pin that extends through the at least one pin hole of the multi-fiber ferrule;
- a crimp sleeve configured to surround the plurality of ribs of the rear end of the connector housing;
- and
- a strain relief boot having a front section and a rear section, the front section defining a front opening having at least one retainer, the strain relief boot secured to the rear end of the connector housing by the at least one retainer engaging with the crimp sleeve and around the outer section of the rear end of the connector housing, wherein when the connector assembly is mounted on the fiber optic cable, the plurality of optical fibers are secured at the multi-fiber ferrule and each of the plurality of optical fibers are inserted within a corresponding fiber hole of the plurality of fiber holes so as to terminate at a front face of the multi-fiber ferrule, and at least a portion of the plurality of strength yarns and the jacket are captured between the plurality of ribs on the outer section and inside the crimp sleeve, with the crimp sleeve securing both the plurality of strength yarns and the jacket to the connector housing.
