An LC format optical connector for terminating an optical fiber includes a housing configured to mate with an LC receptacle. A backbone is configured to engage an outer surface of the outer shell of the housing and includes a mounting structure that is configured to engage a boot. A collar body is retained between the outer shell and the backbone and includes a fiber stub disposed in a first portion of the collar body, the fiber stub being mounted in a ferrule. A mechanical splice is disposed in a second portion of the collar body, the mechanical splice configured to splice the fiber stub to the optical fiber. The backbone also includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the optical fiber upon actuation.

1. An LC format optical connector for terminating an optical fiber, comprising: a housing including an outer shell with an LC format and a front face configured to mate with an LC receptacle, the housing including a resilient latch disposed on a surface of the outer shell and configured to engage the LC receptacle;a backbone configured to engage an outer surface of the outer shell on a first portion thereof and that includes a mounting structure disposed on a second portion thereof;a boot configured to engage the mounting structure of the backbone;a collar body disposed in the housing and retained between the outer shell and the backbone, wherein the collar body includes a fiber stub disposed in a first portion of the collar body, the fiber stub being mounted in a ferrule and having a first end proximate to an end face of the ferrule and a second end; anda mechanical splice disposed in a second portion of the collar body, the mechanical splice configured to splice the second end of the fiber stub to the optical fiber, wherein the backbone also includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the optical fiber upon actuation, and wherein the boot actuates the fiber jacket clamping portion of the backbone upon attachment to the backbone. 2. The LC format optical connector of claim 1, wherein the resilient latch comprises a single-piece latch having a driver formed thereon that is configured to receive a pressing force that disengages the latch from the LC receptacle. 3. The LC format optical connector of claim 1, further comprising an end cap configured to protect an exposed face of the ferrule and mountable on a front face of the housing. 4. The LC format optical connector of claim 3, wherein the end cap further comprises a driver configured to actuate the mechanical splice. 5. The LC format optical connector of claim 4, wherein the end cap is configured such that the driver is positioned over the mechanical splice when the end cap is mounted on the front face of the housing. 6. The LC format optical connector of claim 1, wherein the collar body includes rear portion having a slot formed in an outer surface at a rear end port thereof. 7. The LC format optical connector of claim 6, wherein the rear end portion is tapered towards the rear end port. 8. The LC format optical connector of claim 1, further comprising an elastomeric structure disposed on the mounting structure of the backbone and configured to engage strength members of the optical fiber when the boot is mounted on the mounting structure. 9. The LC format optical connector of claim 1, wherein the boot includes a longitudinal slot formed along a portion of its length that permits the spliced optical fiber to bow outward unrestrained by the boot when engaged with the LC receptacle. 10. The LC format optical connector of claim 1, wherein the backbone includes a flattened backing portion formed on one side of a fiber guide channel. 11. The LC format optical connector of claim 1, wherein the mechanical splice device comprises a splice element and an actuating cap. 12. The LC format optical connector of claim 1, wherein the fiber jacket clamping portion comprises a collet-type, split body shape. 13. The LC format optical connector of claim 1, wherein the boot attaches to the backbone view a screw-type mechanism. 14. The LC format optical connector of claim 1, wherein the backbone further comprises a fiber guide. 15. The LC format optical 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. 16. The LC format optical connector of claim 1, wherein the backbone further comprises an integral coupling mechanism to couple the LC format optical connector to a second LC format optical connector in a multiple connector format. 17. The LC format optical connector of claim 16, wherein the coupling mechanism comprises a dovetail protrusion formed on a first side surface of the backbone and a corresponding slot formed on an opposite side surface of the backbone, wherein the slot is configured to slidingly or snappingly engage a dovetail portion of the backbone of the second LC format optical connector. 18. The LC format optical connector of claim 1, wherein a first portion of the latch is connected to the outer shell near the front face and a second portion of the latch is connected to the outer shell near an opposite end of the outer shell. 19. The LC format optical connector according to claim 1, wherein the backbone is configured to clamp onto an FRP cable. 20. An optical connector for terminating an optical fiber, comprising: a housing including an outer shell and a front face configured to mate with a receptacle of a corresponding format;a backbone configured to engage an outer surface of the outer shell on a first portion thereof and that includes a mounting structure disposed on a second portion thereof;a boot configured to engage the mounting structure of the backbone;a collar body disposed in the housing and retained between the outer shell and the backbone, wherein the collar body includes a fiber stub disposed in a first portion of the collar body, the fiber stub being 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 includes rear portion having a slot formed in an outer surface at a rear end port thereof; anda mechanical splice disposed in a second portion of the collar body, the mechanical splice configured to splice the second end of the fiber stub to the optical fiber, wherein the backbone also includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the optical fiber upon actuation, and wherein the boot actuates the fiber jacket clamping portion of the backbone upon attachment to the backbone. 21. An optical connector for terminating an optical fiber from an FRP cable, comprising: a housing including an outer shell and a front face configured to mate with a receptacle of a corresponding format;a backbone configured to engage an outer surface of the outer shell on a first portion thereof and that includes a mounting structure disposed on a second portion thereof;a boot configured to engage the mounting structure of the backbone;a collar body disposed in the housing and retained between the outer shell and the backbone, wherein the collar body includes a fiber stub disposed in a first portion of the collar body, the fiber stub being 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 includes rear portion having a slot formed in an outer surface at a rear end port thereof; anda mechanical splice disposed in a second portion of the collar body, the mechanical splice configured to splice the second end of the fiber stub to the optical fiber, wherein the backbone also includes a fiber jacket clamping portion to clamp a jacket portion that surrounds a portion of the optical fiber upon actuation, and wherein the boot actuates the fiber jacket clamping portion of the backbone upon attachment to the backbone. 22.
