US 7,116,883 B2 · Fiber optic protective carrier

Abstract

A protective carrier for a fiber optic cable comprises a casing within which is a rotor rotatable in a selected one of two opposite directions. The rotor supports the cable at the axis of rotation of the rotor and the cable extends in opposite directions from such axis and is guided to axially spaced peripheral grooves in which a major portion of the retracted cable is accommodated. From each of the grooves opposite ends of the cable extend through openings in the casing and are coupled to terminations by means of which the cable may be connected to terminals. The openings into the casing accommodate and shield the connectors. The casing is sufficiently rigid to protect the cable and terminations from damage. The path of movement of the cable into and out of the casing is such that the cable is not subjected to kinking or bending in such manner as to damage the cable or attenuate the signal carried by the cable.

Dependent claims

A protective carrier for a fiber optic cable comprises a casing having a first opening and a second opening at opposite sides of said casing;

a rotor mounted in said casing for rotation about an axis, said rotor having two axially spaced annular grooves therein;
a fiber optic cable having opposite ends;
means securing said cable between said opposite ends to said rotor at said axis for rotation with said rotor;
means for rotating said rotor;
first guide means extending from said axis to one of said grooves;
and second guide means extending from said axis to the other of said grooves, said first and second guide means guiding those portions of said cable on opposite sides of said axis from said axis to said first and second grooves respectively, rotation of said rotor in one direction enabling that portion of said cable on one side of said axis to pass through said first opening and outwardly of said casing and that portion of said cable on the opposite side of said axis to pass through said second opening and outwardly of said casing, rotation of said rotor in the opposite direction enabling said portions of said cable to pass through the respective openings and into said casing.
