Optical fiber connector with integrated installation tools
An optical connector having at least one removable integrated assembly tool for terminating an optical fiber cable is described. The connector comprises a housing configured to mate with a receptacle, a collar body disposed in the housing, a backbone that retains the collar body in the housing, a removable funnel-shaped and a fiber boot. The collar body secures a ferrule secured at a first end thereof, and includes mechanical element disposed in an intermediate portion and a buffer clamping portion near a second end of the collar body. The backbone has a mounting structure surrounding a central bore at one end. The funnel-shaped fiber guide attaches to the mounting structure to facilitate insertion of an optical fiber into the connector, and wherein the fiber boot is attachable to the mounting structure after the fiber guide has been removed.

4. The connector of claim 1 , further comprising a fiber stub adhesively mounted in the ferrule wherein a first end of the fiber stub is disposed flush with the end face of the ferrule and a second end of the fiber stub extends beyond the ferrule so that it will extend into an interior of the connector.
5. The connector of claim 4 , wherein the second end of the fiber stub extends into the mechanical element where it will be spliced to a terminal end of the optical fiber cable.
6. The connector of claim 4 , wherein the mechanical element is a mechanical splice element.
7. The connector of claim 1 , wherein the connector comprises an LC format connector or an SC format connector.
8. The connector of claim 1 , further comprising:
a removable funnel-shaped fiber guide attached to the mounting structure to facilitate insertion of an optical fiber into the connector; and
a fiber boot attachable to the mounting structure after the funnel-shaped fiber guide has been removed.
9. The connector of claim 8 , wherein the funnel-shaped fiber guide includes a connection portion to removably connect and align the funnel-shaped fiber guide to the backbone of optical fiber connector and a funnel portion to facilitate insertion of the optical fiber into the collar body of the connector.
10. The connector of claim 9 , wherein the connection portion comprises a box-like cradle that partially surrounds the mounting structure and a pair of catch arms to secure the funnel-shaped fiber guide to the mounting structure.
11. The connector of claim 10 , wherein the pair of catch arms comprises a stationary catch arm and a flexible catch arm.
12. A removable funnel-shaped fiber guide that can be temporarily attached to an optical fiber connector to facilitate insertion of an optical fiber into the optical fiber connector, the funnel-shaped fiber guide comprising:
a connection portion to removably connect and align the funnel-shaped fiber guide to the optical fiber connector, wherein the connection portion comprises a pair of catch arms to secure the funnel-shaped fiber guide to the optical fiber connector; and
a funnel portion to facilitate insertion of the optical fiber into a collar body of the connector, wherein the funnel portion of the funnel-shaped fiber guide includes a channel extending from a narrow end adjacent the connection portion to a wide end spaced away from the connection portion.
13. The funnel-shaped fiber guide of claim 12 , wherein the pair of catch arms comprises a stationary catch arm and a flexible catch arm.
14. The funnel-shaped fiber guide of claim 12 , wherein the connection portion includes one or more alignment walls to help maintain alignment of the funnel portion of the funnel-shaped fiber guide with a second end of the optical fiber connector.
15. The funnel-shaped fiber guide of claim 12 , wherein the channel is tapered from the wide end and the narrow end.
16. An optical fiber connector having at least one removable integrated assembly tool for terminating an optical fiber cable, comprising:
a housing configured to mate with a receptacle;
a collar body disposed in the housing, the collar body securing a ferrule at a first end thereof, a mechanical element disposed in an intermediate second portion of the collar body, and a buffer clamping portion near a second end of the collar body, wherein the buffer clamping portion is configured to clamp at least a portion of a buffer cladding of an optical fiber upon actuation;
a backbone to retain the collar body within the housing, the backbone including a mounting structure surrounding a central bore at one end of the backbone;
a removable funnel-shaped fiber guide attached to the mounting structure to facilitate insertion of an optical fiber into the optical fiber connector, wherein the funnel-shaped fiber guide includes (A) a funnel portion to facilitate insertion of the optical fiber into the collar body of the connector, and (B) a connection portion to removably connect and align the funnel-shaped fiber guide to the backbone of the optical fiber connector, and wherein the connection portion comprises (i) a box-like cradle that partially surrounds the mounting structure and (ii) a pair of catch arms to secure the funnel-shaped fiber guide to the mounting structure; and
a fiber boot attachable to the mounting structure after the funnel-shaped fiber guide has been removed.
17. The connector of claim 16 , wherein the connection portion includes one or more alignment walls to help maintain alignment of the funnel portion of the funnel-shaped fiber guide with the second end of the optical fiber connector.
18. The connector of claim 16 , wherein the funnel portion of the funnel-shaped fiber guide includes a channel extending from a narrow end adjacent the connection portion to a wide end spaced away from the connection portion.
