Patent ID: 7348862

Claim:
An apparatus comprising: at least one of a socket and a corresponding jack that together form a connector for a data transmission medium comprising a plurality of pairs of conductors, comprising for each conductor of each active pair of the pairs of conductors, a pair of common-mode filter inductors connected in series with each other and with the conductor, the pair of inductors having impedance, reactance and resistance characteristics; wherein said impedance, reactance and resistance characteristics substantially meeting or exceeding an impedance curve of FIG. 2 , a reactance curve of FIG. 3 , and a resistance curve of FIG. 4 , respectively, and a direct current-blocking inductor connected in series with each conductor of each inactive pair of the pairs of conductors and ground, the inductor having impedance, reactance and resistance characteristics; wherein said impedance, reactance and resistance characteristics substantially meeting or exceeding an impedance curve of FIG. 5 , a reactance curve of FIG. 6 , and a resistance curve of FIG. 7 , respectively.
