Abstract
A jack with a flexible printed circuit board (FPC) is provided. The FPC is connected to the plug interface contacts and has a compensation circuit to compensate for near-end crosstalk (NEXT) and far-end crosstalk (FEXT). Capacitive and inductive compensation in the compensation circuit are of opposite polarity and are substantially equal in magnitude. The compensation circuit has a FEXT compensation zone containing compensation for the FEXT. Inductive and capacitive compensation in the FEXT compensation zone are distributed.
Claims23
A jack comprising:
- plug interface contacts configured to connect with plug contacts of a plug inserted into the jack;
- and
- a flexible printed circuit (FPC) mechanically and electrically connected to the plug interface contacts, the FPC having a compensation circuit configured to compensate for near-end crosstalk (NEXT) and far-end crosstalk (FEXT), the compensation circuit having inductive and capacitive compensation configured such that the capacitive and inductive compensation are of opposite polarity and substantially equal in magnitude, the compensation circuit having a FEXT compensation zone containing compensation for the FEXT, inductive and capacitive compensation in the FEXT compensation zone being distributed.
A jack comprising:
- plug interface contacts configured to connect with plug contacts of a plug inserted into the jack;
- and
- a flexible printed circuit (FPC) mechanically and electrically connected to the plug interface contacts, the FPC having a compensation circuit configured to compensate for near-end crosstalk (NEXT) and far-end crosstalk (FEXT), the compensation circuit having a FEXT compensation zone containing compensation for the FEXT, inductive and capacitive compensation in the FEXT compensation zone configured such that there is no net effect of the inductive and capacitive compensation on NEXT.
A method of compensating for near-end crosstalk (NEXT) and far-end crosstalk (FEXT) in a communication apparatus, the method comprising:
- providing a flexible printed circuit (FPC) in a jack mechanically and electrically connected to plug interface contacts in the jack, the FPC having a compensation circuit configured to compensate for the NEXT and FEXT, the compensation circuit having:
- inductive and capacitive compensation of opposite polarity and that are substantially equal in magnitude, and
- a FEXT compensation zone containing compensation for the FEXT, inductive and capacitive compensation in the FEXT compensation zone being distributed.
