Abstract
Abstract A fiber optic connector including a fiber securing ferrule which permits fiber cleaving therein. The ferrule includes a slot through its outer surface and internally of the end wall thereof to permit cleaving at a point recessed from the wall. The cleaved fiber end face is positioned within the ferrule thus providing protection thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A method of cleaving an elongate optical fiber comprising the steps of: providing an elongate ferrule having a fiber receiving end, a fiber egressing end, an outer peripheral surface and a longitudinal fiber bore between said ends, said ferrule including a slot through said outer peripheral surface adjacent said fiber egressing end and in communication with said fiber bore; disposing said fiber in said fiber bore, said fiber having an end thereof extending beyond said fiber egressing end of said ferrule; and moving a fiber scoring element into said slot of said ferrule and into contact with said fiber to score said fiber at a fiber location spaced inwardly of said fiber egressing end of said ferrule.
Claim 2
Independent Claim
117 words
A method of cleaving an elongate optical fiber comprising the steps of: providing an elongate ferrule having a fiber receiving end, a fiber egressing end, an outer peripheral surface and a longitudinal fiber bore between said ends, said ferrule including a slot through said outer peripheral surface adjacent said fiber egressing end and in communication with said fiber bore; disposing said fiber in said fiber bore, said fiber having an end thereof extending beyond said fiber egressing end of said ferrule; and moving a fiber scoring element into said slot of said ferrule and into contact with said fiber to score said fiber at a fiber location spaced inwardly of said fiber egressing end of said ferrule.
Claim 3
Dependent Claim
18 words
A method in accordance with claim 1 wherein said disposing step includes: securing said fiber in said ferrule.
Claim 4
Dependent Claim
19 words
A method in accordance with claim 2 wherein said securing step includes: adhesively securing said fiber in said ferrule.
Claim 5
Dependent Claim
14 words
A method in accordance with claim 1 wherein said fiber is a glass fiber.
Claim 6
Independent Claim
121 words
A method of cleaving an elongate optical fiber having a central fiber axis, comprising the steps of: providing an elongate ferrule having a fiber receiving end, a fiber egressing end, an outer peripheral surface and a longitudinal fiber bore between said ends, said ferrule including a slot through said outer peripheral surface adjacent said fiber egressing end and in communication with said fiber bore; disposing said fiber in said fiber bore, said fiber having an end thereof extending beyond said fiber egressing end of said ferrule; and moving a fiber scoring element in a direction perpendicular to said fiber axis to score said fiber through said slot at a fiber location spaced inwardly of said fiber egressing end of said ferrule.
Claim 7
Independent Claim
121 words
A method of cleaving an elongate optical fiber having a central fiber axis, comprising the steps of: providing an elongate ferrule having a fiber receiving end, a fiber egressing end, an outer peripheral surface and a longitudinal fiber bore between said ends, said ferrule including a slot through said outer peripheral surface adjacent said fiber egressing end and in communication with said fiber bore; disposing said fiber in said fiber bore, said fiber having an end thereof extending beyond said fiber egressing end of said ferrule; and moving a fiber scoring element in a direction perpendicular to said fiber axis to score said fiber through said slot at a fiber location spaced inwardly of said fiber egressing end of said ferrule.
