METHOD TO REDUCE CROSSTALK IN FOUR-WIRE ELECTRIC DATA TRANSFER LINES Russian patent published in 2011 - IPC H04B3/32 

FIELD: information technologies.

SUBSTANCE: groups of copper strand pairs are used so that data is sent along data transfer lines accordingly from two transmitting devices and two receiving ones, the input and output of the four-wire communication line are connected to a single-type device, which comprises the following components: a transformer, on each of two cores of which there is an input winding, the first and the second output windings. Besides, the first output windings of cores are connected in series, the second output windings of cores are connected oppositely, and reactive resistances of the input windings are equal and are twice more than the reactive resistances of the output windings.

EFFECT: reduced crosstalk in any electric transfer lines.
