摘要:
An electrical connector has a first shell, an opposing second shell and a circuit board between the first shell and the second shell. The circuit board has a first side and an opposing second side and includes a plurality of differential pair conductive traces on each side. A first drain wire termination device is provided on the first side and includes at least one separator between at least one of the differential pair conductive traces on the first side and another of the differential pair conductive traces on the first side. A second drain wire termination device is connected to the second side and includes at least one separator between at least one of the differential pair conductive traces on the second side and another of the differential pair conductive traces on the second side.

A communication connector is described that includes a plug and a jack, into which the plug is inserted. The plug terminates a length of twisted pair cable. The jack includes a sled to support contacts for connecting to wires within the cable, a rigid circuit board that connects to the contacts, and a flex board that contacts the plug interface contacts. The jack also includes circuitry to compensate for crosstalk between wire pairs of the cable by adding capacitance values within the sled, rigid circuit board and/or flex board between traces carrying signals from the wire pairs so that crosstalk caused by the plug between wire pairs that have signals in phase cancels with crosstalk caused by the plug between signals out of phase, and so that the capacitance values added between each trace are about equal. The compensation is performed to reduce differential to common mode signal conversion.

A device for providing transient voltage suppression on a Power over Ethernet system is provided. The device includes a transient voltage suppression module. The transient voltage suppression module includes a circuit module, which includes a circuit board and input and output connectors. One or more transient voltage suppression modules may be mounted to a frame to form a transient voltage suppression patch panel, which, in turn, may be mounted to a rack for use in a telecommunications room. The circuit board combines a frequency-variable impedance connected between conductors in a pair and a voltage-variable impedance connected to the frequency-variable impedance, where the voltage-variable impedance is also connected to a chassis and/or an electrical ground.

A communication connector uses compensation circuitry to compensate for crosstalk in a network connection. Capacitors are connected between specific conducive paths in said communication connector. Inductive stubs are utilized in the compensation circuitry to improve the overall compensation performance.
