Abstract
Abstract A high performance modular connector system includes a plug and a jack both arranged for high frequency data transmission. The plug is constructed for coupling in a mating arrangement with the jack both including a plurality of contacts arranged to provide conductive paths for carrying a high-frequency data signal. The connector system includes several counter-coupling or compensation structures, each having a specific function in cross-talk reduction. The compensation structures are designed to offset and thus electrically balance frequency-dependent capacitive and inductive coupling. One important type of the compensation structure is located near contact points forming the conductive paths between connector terminals of the jack and connector terminals of the plug. This compensation structure is conductively connected to at least some of the contacts and is located outside the conductive path carrying the high-frequency data signal. This compensation structure may be connected to contacts of the jack or contacts of the plug.
