Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
A method of terminating an end of a fiber optic cable in a fiber optic connector, comprising the sequential steps of: positioning the end of the fiber optic cable within a passageway of the fiber optic ferrule along with a solidifiable encapsulant material until an exposed end of an optic waveguide extends outwardly beyond a forward end of said ferrule; placing said forward end of said ferrule within a bore of a fixture with said exposed end of said waveguide extending through a hole in said fixture, said hole being concentric with said bore so that the axis of said exposed end of said waveguide is in coincident alignment with the axis of said ferrule; solidifying said encapsulant material thereby securing the end of the fiber optic cable in said ferrule; removing said fixture from said forward end of said ferrule; and polishing said exposed end of said waveguide.
Claim 2
Independent Claim
149 words
A method of terminating an end of a fiber optic cable in a fiber optic connector, comprising the sequential steps of: positioning the end of the fiber optic cable within a passageway of the fiber optic ferrule along with a solidifiable encapsulant material until an exposed end of an optic waveguide extends outwardly beyond a forward end of said ferrule; placing said forward end of said ferrule within a bore of a fixture with said exposed end of said waveguide extending through a hole in said fixture, said hole being concentric with said bore so that the axis of said exposed end of said waveguide is in coincident alignment with the axis of said ferrule; solidifying said encapsulant material thereby securing the end of the fiber optic cable in said ferrule; removing said fixture from said forward end of said ferrule; and polishing said exposed end of said waveguide.
Claim 3
Dependent Claim
35 words
The method as recited in claim 1, wherein, polishing a portion of said waveguide includes, removing at least portions of said fixture and polishing said portion of said waveguide flush with said ferrule forward end.
Claim 4
Dependent Claim
22 words
The method as recited in claim 1, wherein, removal of said fixture is performed prior to polishing said portion of said waveguide.
Claim 5
Dependent Claim
34 words
The method as recited in claim 1, and further including the step of: applying an adhesive releasable material on said fixture prior to assembly thereof on said portion of said waveguide and said ferrule.
Claim 6
Dependent Claim
60 words
The method as recited in claim 1, wherein, said waveguide includes cladding covering a light transmitting core, and said portion of said waveguide comprises a portion of said core, and further including the steps of: removing said cladding from said portion of said core prior to projection thereof beyond said ferrule forward end and into said hole of said fixture.
Claim 7
Dependent Claim
38 words
The method as recited in claim 5, wherein, polishing a surface of said portion of said waveguide includes, polishing a surface of said portion of said core flush with said cladding and flush with said ferrule forward end.
