Estimating the term…
The transmission members of a communications cable are effectively rearranged in their relative locations within a cable core of predetermined end array configuration, by assigning all defective members to a designated small area of the end configuration. As a result, when gang type connectors are applied at the cable core ends preparatory to straight-through splicing, the defective members are all relegated to a designated, fixed end region of the connector. When several such cables are spliced together, the defective members occasion a minimum of transmission path disabling, because they are largely connected to each other instead of being distributed throughout the entire cable cross section where their potential disabling impact would be proliferated. The approach is particularly advantageous for mitigating transmission path disabling in optical fiber cables in which the core consists of several stacked multi-fiber ribbons.
A communications cable comprising a core of transmitting members defined as a complete set including one or more defective members, CHARACTERIZED IN THAT the ends of the defective members are rearranged to appear only in a defined subset of adjacent end positions.
An optical fiber cable section comprising a core of fibers consisting of a stack of fiber-containing ribbons forming an x-y matrix of fibers at the section ends and including one or more non-transmitting fibers, CHARACTERIZED IN THAT the non-transmitting fibers are rearranged to appear only in a defined contiguous subset of fiber end positions.
A method of mitigating broken fiber effects in an optical fiber cable consisting of a core of fibers including one or more non-transmitting fibers, comprising the steps of rearranging the broken fibers to occupy positions only within a defined contiguous subset of fiber ends.
A method of mitigating broken fiber effects in an optical fiber cable comprising a core of fiber-containing ribbons, stacked to form at its ends an x-y matrix of fiber ends and including one or more non-transmitting fibers, comprising the step of:
An optical fiber cable comprising a plurality of fibers spaced cross-sectionally in a predetermined configuration, in which any broken fibers of said cable are arranged to appear only in a fixed designated zone of the fiber matrix at either end of the said cable.
A communications cable comprising a core consisting of a multiplicity of individual transmission paths including one or more defective paths CHARACTERIZED IN THAT the end configuration of the transmission paths is predetermined and the defective paths are rearranged to appear only in a defined subset of end positions.
