Abstract
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.
