1. A high speed communication jack comprising:
- a housing including a port for accepting a plug, the port including a plurality of pins each connected to a corresponding signal line in the plug;
a shielding case surrounding the housing;
a circuit board disposed in part between the shielding case and the housing, wherein the circuit board comprisesa substrate having a first side and a second side opposite the first side,a plurality of pin vias extending through the substrate where each of the pin vias is configured to accommodate a pin on the housing,a plurality of traces on the first side of the substrate where each trace extends from a corresponding one of the plurality of pin vias;
a shielding trace layer disposed on the first side of the substrate including a pair of shielding tabs disposed on opposite edges of the first side of the substrate and a shielding trace disposed on the first side of the substrate opposite the first plurality of pin vias where the shielding trace extends between and connects the shielding tabs,a shielding plane on the second side of the substrate,a plurality of return vias extending through the substrate with each of the return vias connecting the shielding trace layer and the shielding plane,wherein, a height, width, length and spacing of at least two traces are adjusted such that an impedance of the at least two traces is substantially the same.
