A method and apparatus are disclosed for reducing cross-talk in an unbalanced channel with a reduced number of redundancies. A cross-talk canceller is disclosed that uses a multi-dimensional finite impulse response (FIR) filter to process a received signal. Redundancies are reduced or even removed entirely by processing the signals received on each twisted pair in a vector form, using multi-dimensional finite impulse response filters. The signals received by a transceiver on each twisted pair are represented in a vector form so that the signals received on each twisted pair, and the cross-talk effect that each signal has on one another, can be performed collectively. A multi-dimensional cross-talk canceller processes a vector representation of the corresponding signals transmitted by the transceiver on each twisted pair. An adder sums the equalized vector representation of the signals received by the transceiver and the processed vector representation of the signals transmitted by the transceiver to generate an estimate of the received signal on each twisted pair.

A connector assembly includes a housing having housing cavities extending between a mating end and a loading end. The housing having module latches associated with corresponding housing cavities. Contact modules are received in corresponding housing cavities. Each contact module having first and second module cavities extending between a front end and a rear end of the contact modules. The contact modules being held within the housing cavity by the corresponding module latch. Each contact module having an unshielded twisted pair (UTP) circuit, the UTP circuit includes first and second signal wires and first and second terminals terminated to the first and second signal wires. The signal wires being twisted along a length of the first and second signal wires.

The invention provides a double-netport physical isolation card to use effectively double-network resource and realize true physical isolation, which comprises a network chip interconnected to microcontroller chip that connects to IDE interface and following control circuit, network selection chip and relay control circuit selected set on two RJ45 twisted-pair to different network.

The invention discloses a two-core twisted-pair cable. The two-core twisted-pair cable comprises main cable cores, a tape wrapping layer, a waterproof layer, a shielding layer and a protective jacket. The main cable cores are divided into three sets, and each set of main cable core is formed by two tin plating insulating cable cores in a twisted-pair mode. A reinforcing plate is arranged inside the tape wrapping layer, and the cross section of the reinforcing plate is formed by the way that three insulating plates intersect at one end. The tape wrapping layer is evenly divided into three windowpanes, and the main cable cores are located in the three windowpanes respectively. The shielding layer is formed by the way that an inner shielding layer is in cross linkage with an outer shielding layer. The two-core twisted-pair cable is good in electrical conductivity, long in service life, resistant to high temperatures, fireproof, resistant to oil, capable of protecting corrosion, mainly applicable to the fields of computers, communication, electricity generation, chemical engineering, petroleum and the like, waterproof, resistant to oxidation, high in shielding property, resistant to dragging, and firm in cable core.
