Telecommunications device

摘要

The present disclosure relates to a telecommunications jack including a housing having a port for receiving a plug. The jack also includes a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing, and a plurality of wire termination contacts for terminating wires to the jack. The jack further includes a circuit board that electrically connects the contact springs to the wire termination contacts. The circuit board includes a multi-zone crosstalk compensation arrangement for reducing crosstalk at the jack.

1. A telecommunications device comprising:
a housing defining a port for receiving a plug; a plurality of contact springs adapted to make electrical contact with the plug when the plug is inserted into the port of the housing; a plurality of wire insulation displacement contacts for terminating wires to the device; a circuit board including conductive tracks that electrically connect the contact springs to the wire termination contacts, the circuit board including a first conductive layer, a second conductive layer, and a third conductive layer, the first and second conductive layers separated by a first dielectric layer and the second and third conductive layers separated by a second dielectric layer; and a cross talk compensation arrangement that provides crosstalk compensation between selected tracks of the circuit board, the crosstalk compensation arrangement including a capacitive coupling of a first zone of compensation positioned a first time delay away from a source of crosstalk located at the plug, a capacitive coupling of a second zone of compensation positioned a second time delay away from the first zone of compensation, and a capacitive coupling of a third zone of compensation positioned a third time delay away from the second zone of compensation; the first zone of compensation including a first set of opposing capacitor plates positioned at the first and second conductive layers; the second zone of compensation including a second set of opposing capacitor plates positioned at the first and second conductive layers; and the third zone of compensation including a third set of opposing capacitor plates positioned at the first and second conductive layers and interdigitated capacitor fingers positioned at the third conductive layer.
