Abstract
Abstract An optical fiber cable having a loop of strong braided sheath anchored within it to provide terminal strength and a protective tube surrounding the optical fibers of the cable as they exit the cable through a gap in the sheath for termination. The protective tube allows retention of signal quality of optical fibers by preventing damage to coating layers on the fibers passing through the braided sheath which may be under high tension.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
57 words
A terminated optical fiber cable including a braided sheath surrounding one or more optical fibers and a short segment of protective means surrounding the optical fibers at a point where said fibers pass through an opening in the weave of the braid of said braided sheath at a specified distance from the terminated end of said cable.
Claim 2
Dependent Claim
57 words
A terminated optical fiber cable including a braided sheath surrounding one or more optical fibers and a short segment of protective means surrounding the optical fibers at a point where said fibers pass through an opening in the weave of the braid of said braided sheath at a specified distance from the terminated end of said cable.
Claim 3
Dependent Claim
15 words
An optical fiber cable of claim 1 wherein said protective means comprises a hollow tube.
Claim 4
Dependent Claim
14 words
An optical fiber cable of claim 2 wherein said tube comprises metal or plastic.
Claim 5
Dependent Claim
27 words
An optical fiber cable of claim 1 or 2 having a loop formed in the end of said braided sheath for anchoring said cable to a connector.
Claim 6
Dependent Claim
237 words
A process for terminating a braided sheath surrounding a cable comprising the steps of: (a) separating the fibers of said sheath at a point several inches from the end of said sheath to form a first opening in said sheath; (b) extracting said cable from said opening in said sheath; (c) inserting a thin narrow tool, having an eye at one end, eye first through said first opening in said braided sheath to a point about half way to the end of said sheath and out of said sheath through a second opening formed therein by separating the fibers of said braided sheath; (d) threading the end of said braided sheath through the eye of said tool; (e) pulling said end of said braided sheath as a unit inside said braided sheath through said second opening to leave said end of braided sheath buried inside said braided sheath and a loop in the end of said braided sheath as said tool is withdrawn from said first opening in said braided sheath; (f) passing said cable end into said protective means; (g) sliding said protective means over the end of and around said cable to said first opening in said braided sheath; (h) inserting said protective means through said first opening to reside partially inside said braided sheath while surrounding said cable; (i) anchoring said protective means to said braided sheath to hold said protective means in place.
Claim 7
Dependent Claim
237 words
A process for terminating a braided sheath surrounding a cable comprising the steps of: (a) separating the fibers of said sheath at a point several inches from the end of said sheath to form a first opening in said sheath; (b) extracting said cable from said opening in said sheath; (c) inserting a thin narrow tool, having an eye at one end, eye first through said first opening in said braided sheath to a point about half way to the end of said sheath and out of said sheath through a second opening formed therein by separating the fibers of said braided sheath; (d) threading the end of said braided sheath through the eye of said tool; (e) pulling said end of said braided sheath as a unit inside said braided sheath through said second opening to leave said end of braided sheath buried inside said braided sheath and a loop in the end of said braided sheath as said tool is withdrawn from said first opening in said braided sheath; (f) passing said cable end into said protective means; (g) sliding said protective means over the end of and around said cable to said first opening in said braided sheath; (h) inserting said protective means through said first opening to reside partially inside said braided sheath while surrounding said cable; (i) anchoring said protective means to said braided sheath to hold said protective means in place.
Claim 8
Dependent Claim
22 words
A process of claim 5 also including anchoring said loop of said braided sheath over a connector pin and terminating said cable.
