Abstract
Abstract The invention provides for a dielectric optical fiber cable reinforced by a yarn made by spinning synthetic staple fibers around a glass core. The optical fibers are sheathed by the yarn reinforced glass core and then enclosed in a polyethylene jacket. When heated, the yarn fuses with the polyethylene jacket forming a rigid cable member.

Independent Claim
39 words
An optical cable member comprising at least one optical fiber wrapped with a sheath of yarn, said yarn consisting of a core member encased with spun synthetic staple fibers and an outer jacket surrounding said yarn wrapped optical fiber.
Claim 2
Dependent Claim
39 words
An optical cable member comprising at least one optical fiber wrapped with a sheath of yarn, said yarn consisting of a core member encased with spun synthetic staple fibers and an outer jacket surrounding said yarn wrapped optical fiber.
Claim 3
Dependent Claim
18 words
The optical cable of claim 1, wherein said core member of said yarn consists of a glass member.
Claim 4
Dependent Claim
14 words
The optical cable of claim 1, wherein said yarn is composed of aramid fibers.
Claim 5
Dependent Claim
15 words
The optical cable of claim 1, wherein said yarn is composed of a thermosetting material.
Claim 6
Dependent Claim
18 words
The optical cable of claim 1, wherein said yarn consists of polyester staple fibers spun over glass fibers.
Claim 7
Dependent Claim
15 words
The optical cable of claim 5, wherein said outer jacket is further composed of polyethylene.
Claim 8
Dependent Claim
14 words
The optical cable of claim 1, wherein said outer jacket is composed of polyethylene.
Claim 9
Dependent Claim
37 words
A dielectric cable member comprising a core member wrapped in a sheath of yarn, said yarn consisting of a glass fiber encased with spun synthetic staple fibers and an outer jacket surrounding said yarn wrapped core member.
Claim 10
Dependent Claim
37 words
A dielectric cable member comprising a core member wrapped in a sheath of yarn, said yarn consisting of a glass fiber encased with spun synthetic staple fibers and an outer jacket surrounding said yarn wrapped core member.
Claim 11
Dependent Claim
16 words
The cable member of claim 8, wherein said core member includes at least one optical fiber.
Claim 12
Dependent Claim
20 words
The cable member of claim 8, wherein said yarn is composed of polyester staple fibers spun over said glass fiber.
Claim 13
Dependent Claim
15 words
The cable member of claim 10, wherein said outer jacket is further composed of polyethylene.
Claim 14
Dependent Claim
16 words
The cable member of claim 8, wherein said outer jacket is composed of a thermosetting material.
Claim 15
Dependent Claim
42 words
An optical cable member comprising at least one optical fiber wrapped with a sheath of yarn, said yarn consisting of a glass core member encased with synthetic staple fibers, and an outer jacket composed of polyurethane surrounding said yarn wrapped optical fiber.
Claim 16
Dependent Claim
42 words
An optical cable member comprising at least one optical fiber wrapped with a sheath of yarn, said yarn consisting of a glass core member encased with synthetic staple fibers, and an outer jacket composed of polyurethane surrounding said yarn wrapped optical fiber.
Claim 17
Dependent Claim
60 words
The cable member of claim 13, wherein said synthetic staple fibers are composed of a thermosetting material, whereby said cable member is flexible until application of heat to said cable member to melt said synthetic staple fibers and said polyurethane, thereby providing a blended outer sheath surrounding said optical fiber which, upon cooling, stiffens to produce a non-flexible cable member.
