Abstract
A cross-talk compensaring circuit member for use with communications systems connector arrays. The circuit member comprises a wiring board on which are printed conductive paths for each of the leads of the several (usually four) pairs in a connector jack, and the board may accommodate several such jacks. The conductive paths are routed in a manner to create facing inductive loop portions which are substantially mirror images of each other to produce inductive interaction among the different pair combinations. Capacitive coupling is also used in one embodiment.

For use in a connector arrangement in a communication system, a cross-talk compensaring member comprising:
- a planar substrate (18) having first and second surfaces (41,42);
- connector members (1-8) on said substrate for conductively receiving the first and second leads of at least two conductor pairs;
- said substrate having conductive paths thereon connecring each of the connector members to output members (47, 49, 53, 56, 59, 63, 67, 68) wherein the conductive paths (51, 54) connected to the first (4) and second (5) connector members of a first conductor pair (R.sub.1, T.sub.1) and the conductive paths (57, 61) connected to the first (6) and second (3) connector members of a second conductor pair (R.sub.3, T.sub.3) form first and second facing planar inductive loop portions, said first and second loop portions lying in planes parallel to and facing each other, said planes being normal to the plane of said substrate, and adapted to interact with each other to induce compensaring cross-talk between said first and second conductor pairs.
For use in a connector arrangement in a communication system, a cross-talk compensaring member comprising:
- a planar substrate having first and second surfaces (41, 42);
- connector members (1-8) on said substrate for conductively receiving the first and second leads of at least three conductor pairs, connectors 1 and 2 receiving the third conductor pair;
- said substrate having conductive paths thereon connecring each of the connector members to output members (47, 49, 53, 56, 59, 63, 67, 68) wherein the conductive paths connected to the first and second connector members of a first conductor pair and the conductive paths connected to the first and second connector members of a second conductor pair form first and second facing inductive loop portions adapted to interact with each other to induce compensaring cross-talk between said first and second conductor pairs;
- wherein said connector member (2) for receiving the first lead of the third pair is connected to a fifth conductive path (43) on said first surface (41) of said substrate (18) and the connector member (1) for receiving the second lead of the third pair is connected to a sixth conductive path (48) on said first surface (41) of said substrate (18), said fifth (43) and said sixth (48) conductive paths being spaced apart over a portion of their lengths sufficiently to form a fifth inductive loop portion on said first surface (41);
- and
- wherein said third (57) and fourth (61) conductive paths are spaced apart over a portion of their lengths sufficient to form a sixth inductive loop on said second surface (42) facing said fifth inductive loop portion.
