Abstract
Abstract A technique for protecting an optical fibre breakout particularly from a cable 1 comprising a core 2, a plurality of loose fibres 3 and a jacket 5. The jacket 5 and core 2 are stripped back and the fibres encased in protective tubes 7. This may be done one fibre at a time by removing a portion of cable jacket remote from the end and withdrawing each fibre from under the remaining end portion of jacket. The cable may be held in a holding tool and the fibres inserted into their protective tubes by means of an insertion tool.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
74 words
A kit-of-parts suitable for terminating an optical fiber cable having optical fibers disposed cylindrically therearound, comprising: a plurality of protective tubes each suitable for housing individual ones of the optical fibers; a heat-shrinkable sleeve suitable for securing the tubes with respect to the terminated cable; means for identifying respective protective tubes; and means for correlating the identification of the tubes with respective fibers of the cable, the fibers being disposed cylindrically around the cable.
Claim 2
Dependent Claim
74 words
A kit-of-parts suitable for terminating an optical fiber cable having optical fibers disposed cylindrically therearound, comprising: a plurality of protective tubes each suitable for housing individual ones of the optical fibers; a heat-shrinkable sleeve suitable for securing the tubes with respect to the terminated cable; means for identifying respective protective tubes; and means for correlating the identification of the tubes with respective fibers of the cable, the fibers being disposed cylindrically around the cable.
Claim 3
Dependent Claim
52 words
A kit-of-parts according to claim 1, in which the means for identifying comprises colour-coding of the tubes; and the means for correlating comprises a card which matches the colour-coding of the tubes with a position indicator of the cable which identifies the fibers by means of their relative position in the cable.
Claim 4
Dependent Claim
26 words
A kit-of-parts according to claim 1 which additionally comprises a gel or mastic for providing an invironmental seal at an end portion of a protective tube.
Claim 5
Dependent Claim
60 words
A kit-of-parts according to claim 1, in which the means for identifying comprises an article to which the tubes are attached, the article being colour-coded; and the means for correlating comprises a card which matches the colour-coding of the tubes with a position indicator of the cable which identifies the fibers by means of the relative position in the cable.
Claim 6
Dependent Claim
26 words
A kit-of-parts according to claim 4 which additionally comprises a gel or mastic for providing an environmental seal at an end portion of a protective tube.
