Abstract

Abstract A laminated fiber optic ribbon cable, and method of manufacturing same, is disclosed. The cable comprises top and bottom sheath layers, at least two elongate reinforcement members each located along respective sides of the bottom sheath layer, and a plurality of spaced apart and parallel waveguides positioned upon the bottom sheath layer between the two reinforcement members. Subsequent to the introduction of insulary filler material between the sheath layers, longitudinal edge portions of the sheath layers are bonded together at each side of the cable, with longitudinal gaps being thereby defined along each side of the cable between the bonded sheath edge portions and the two cable reinforcement members. Preparation of the cable for termination may thereby be effectuated by cutting into the longitudinal gaps and peeling back the top sheath layer to access the waveguides and strength members therebeneath.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 114 words
A fiber optic ribbon cable comprising: bottom sheath means; a plurality of strength member means spaced from one another and extending along said bottom sheath means; optic waveguide means disposed between the spaced strength member means and extending along said bottom sheath means; means bonding said strength member means in fixed positions on said bottom sheath means; means adhesively securing said optic waveguide means on said bottom sheath means between the spaced strength member means; insulary material filler means covering said optic waveguide means between said strength member means; and top sheath means extending along said strength member means and said insulary material filler means with edge portions of said sheath means bonded together.
Claim 2
Dependent Claim 114 words
A fiber optic ribbon cable comprising: bottom sheath means; a plurality of strength member means spaced from one another and extending along said bottom sheath means; optic waveguide means disposed between the spaced strength member means and extending along said bottom sheath means; means bonding said strength member means in fixed positions on said bottom sheath means; means adhesively securing said optic waveguide means on said bottom sheath means between the spaced strength member means; insulary material filler means covering said optic waveguide means between said strength member means; and top sheath means extending along said strength member means and said insulary material filler means with edge portions of said sheath means bonded together.
Claim 3
Dependent Claim 21 words
A fiber optic ribbon cable as set forth in claim 1, wherein said insulary material filler means comprises a silicone foam.
Claim 4
Dependent Claim 22 words
A fiber optic ribbon cable as set forth in claim 1, wherein each said strength member has a flat rectangular sectioned profile.
Claim 5
Independent Claim 113 words
A method of forming a laminated fiber optic cable, comprising the steps of: bonding a sheet of material means to a bottom sheath layer; cutting said sheet in axial strips along said bottom sheath layer; peeling off said strips leaving at least two strips on said bottom sheath layer as strength members spaced a distance from respective sides of said bottom sheath layer; positioning optic waveguides between said strength members in mutually parallel spaced apart relation; covering said strength members with a top sheath layer so that each said strength member is likewise located a distance from a respective side of top sheath layer; and bonding edge portions of said sheath layers together.
Claim 6
Independent Claim 113 words
A method of forming a laminated fiber optic cable, comprising the steps of: bonding a sheet of material means to a bottom sheath layer; cutting said sheet in axial strips along said bottom sheath layer; peeling off said strips leaving at least two strips on said bottom sheath layer as strength members spaced a distance from respective sides of said bottom sheath layer; positioning optic waveguides between said strength members in mutually parallel spaced apart relation; covering said strength members with a top sheath layer so that each said strength member is likewise located a distance from a respective side of top sheath layer; and bonding edge portions of said sheath layers together.
Claim 7
Dependent Claim 38 words
A method as set forth in claim 4, including the step of filling the space between said strength members and covering said waveguides with insulary material means prior to covering said strength members with said top sheath layer.
