    • 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.
    • 描述了包括插头和插座的通信连接器,插头插入插座和插座。 插头终止一双双绞线电缆。 千斤顶包括一个滑板以支撑用于连接到电缆内的电线的触点,连接到触点的刚性电路板,以及接触插头接口触点的挠性板。 千斤顶还包括电路,用于通过在线缆,刚性电路板和/或柔性板之间增加电容值来补偿电缆的线对之间的串扰,承载来自导线对的信号的迹线,使得由线对之间的插头引起的串扰 具有相位消除的信号,其中由相互之间的信号之间的插头引起的串扰相消,并且使得在每个迹线之间添加的电容值大致相等。 执行补偿以减小差模到共模信号转换。
