摘要: Communication cables are provided in which a core lay length of the cable varies along the cable length. The cable may be provided with different segments that have different core lay lengths. It is desirable for neighboring core lay lengths in a cable to differ by a factor of two, to enable a reduction in power-sum alien near-end crosstalk (PSANEXT) when two cables are installed alongside one another. Segments of the cable having different core lay lengths may be spaced periodically along the length of the cable, and the periodicity of the spacing may be altered by a jitter distance. The introduction of jitter into the periodicity of the spacing of the segments increases the likelihood that a beneficial placement of core lay lengths will occur when two or more cables are installed alongside one another.

摘要: Systems and methods for decreasing alien crosstalk use enhanced patch cords for introducing additional attenuation. The enhanced patch cords are preferably shielded to reduce alien crosstalk down their lengths and also attenuate signals passing therethrough to a greater extent than standard communication patch cords. The interaction of two enhanced patch cords results in two suppression steps for alien crosstalk and only one suppression step for intended signal passing through a communication cable.
