Modular insert and jack including moveable reactance section

Abstract

Compensation schemes for a modular jack are provided according to the present disclosure. The compensation schemes advantageously include a first coupling of compensating crosstalk between a first pair of conductors and a second pair of conductors and a second coupling of compensating crosstalk between only a first conductor of the first pair of conductors and only a first conductor of the second pair of conductors, wherein the first and second couplings of compensating crosstalk are of opposite polarities. In exemplary embodiments, the first coupling of compensating crosstalk may be provided by a circuit board, such as a flexible circuit board including a plurality of interconnection elements, e.g., capacitors, for providing the first coupling of compensating crosstalk. Alternatively, the first coupling of compensating crosstalk may be provided by a plurality of plug interface contacts associated with the first and second pairs of conductors. Similarly, the second coupling of compensating crosstalk may be provided either by a circuit board associated with the first and second pairs of conductors or by a plurality of rear wire connection terminals associated with the first and second pairs of conductors.
