Abstract
Abstract An optical fiber cable having a predetermined length includes a plurality of optical fibers, each fiber having first and second ends. The first ends of the fibers are located coincidental with a first end of the optical fiber cable. The optical fibers are provided with differing lengths so that the second ends of the optical fibers are disposed at different locations along the length of the optical fiber cable. Indicia are provided on the cable to indicate the locations of the second ends of the fibers.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
121 words
An optical fiber cable having a predetermined length, comprising: a cable jacket of said predetermined length and having first and second ends; a plurality of optical fibers disposed within and enclosed by said cable jacket, said fibers having first and second ends, the first end of each said fiber being coincident with the first end of said cable jacket, said fibers having various lengths such that the second ends of said fibers are located at various positions along the length of said cable, at least one of said second ends being at a position enclosed by the cable jacket; and first indicia disposed on an outer surface of said cable jacket identifying the positions of the second ends of said fibers.
Claim 2
Dependent Claim
121 words
An optical fiber cable having a predetermined length, comprising: a cable jacket of said predetermined length and having first and second ends; a plurality of optical fibers disposed within and enclosed by said cable jacket, said fibers having first and second ends, the first end of each said fiber being coincident with the first end of said cable jacket, said fibers having various lengths such that the second ends of said fibers are located at various positions along the length of said cable, at least one of said second ends being at a position enclosed by the cable jacket; and first indicia disposed on an outer surface of said cable jacket identifying the positions of the second ends of said fibers.
