Abstract

An optical fiber connector includes a housing configured to mate with a receptacle, a collar body that includes a fiber stub and a mechanical splice device, a backbone to retain the collar body within the housing, and a boot. The backbone includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the terminated optical fiber upon actuation. The boot actuates the fiber jacket clamping portion of the backbone upon attachment to the backbone. The optical fiber connector can be terminated in the field without the need to use a separate termination platform or tool.

Claims (11)

1. An optical fiber connector for terminating an optical fiber cable, comprising:

a first optical fiber disposed within the optical fiber cable, the optical fiber cable comprising a rectangular jacket surrounding the first optical fiber;

a housing configured to mate with a receptacle;

a collar body disposed in the housing, wherein the collar body includes a fiber stub disposed in a first end portion of the collar body, the fiber stub including a second optical fiber mounted in a ferrule and having a first end proximate to an end face of the ferrule and a second end, wherein the collar body further includes a mechanical splice device disposed in a portion of the collar body, the mechanical splice device configured to splice the second end of the fiber stub to the first optical fiber;

a backbone to retain the collar body within the housing, the backbone including a jacket clamping portion to clamp the jacket portion upon actuation; and

a boot attachable to a portion of the backbone, wherein the boot actuates the jacket clamping portion of the backbone upon attachment to the backbone.

2. The optical fiber connector of claim 1 , wherein the optical connector is configured to mate with an SC receptacle.

3. The optical fiber connector of claim 1 , wherein the fiber jacket clamping portion comprises a split body shape.

4. The optical fiber connector of claim 1 , wherein the boot attaches to the backbone view a screw-type mechanism.

5. The optical fiber connector of claim 1 , wherein the backbone includes stops formed on an inner surface thereof to prevent passage of a jacketed fiber from further insertion.

6. The optical fiber connector of claim 1 , wherein the optical connector is configured to mate with an LC receptacle.
