1. A telecommunications connector comprising:

  • a plurality of electrical conductors arranged in differential pairs;

    a circuit board having a plurality of conductive layers, the plurality of conductive layers including a first conductive layer, a second conductive layer and a third conductive layer, the second conductive layer being positioned between the first and third conductive layers, the circuit board including a cross-talk compensation arrangement for applying capacitance between at least some of the electrical conductors, the cross-talk compensation arrangement including a plurality of open-ended conductive paths that provide a first capacitive coupling at a first discrete capacitive coupling location at the first conductive layer and a second capacitive coupling at a second discrete capacitive coupling location at the third conductive layer, the second conductive layer including a conductive plate positioned between the first and second discrete capacitive coupling locations, the conductive plate including a first surface that faces toward the first discrete capacitive coupling location and an opposite second surface that faces toward the second discrete capacitive coupling location, wherein the conductive plate and the first and second discrete capacitive coupling locations are relatively positioned such that;

    a) the first surface is adapted to reflect radiant energy from the first discrete capacitive coupling location back towards the first discrete capacitive coupling location to intensify the first capacitive coupling; and

    b) the second surface is adapted to reflect radiant energy from the second discrete capacitive coupling location back towards the second discrete capacitive coupling location to intensify the second capacitive coupling.
