Abstract
The present disclosure relates to a telecommunications connector having cross-talk compensations, and a method of managing alien crosstalk in such a connector. In one example, the telecommunications connector includes electrical conductors arranged in differential pairs and a circuit board with conductive layers that provide a cross-talk compensation arrangement for applying capacitance between the electrical conductors. The circuit board includes conductive paths that provide capacitive coupling and a conductive plate that intensifies capacitive coupling of the electrical conductors. In another example, the telecommunications connector is used with a twisted pair system. Capacitances applied by the crosstalk compensation arrangement between electrical conductors associated with the pairs are provided such that, for each differential pair, a magnitude of an overall capacitance at a first electrical conductor of a differential pair is approximately equal to a magnitude of an overall capacitance at a second electrical conductor of the differential pair.
