Arrangements for suppressing crosstalk in multiconductor transmission lines

摘要

The invention relates to devices intended for data transmission, having internal shielding to reduce crosstalk, in particular, to data transmission lines, twisted pair. The purpose of the utility model is to provide the possibility of suppressing crosstalk in multi-wire electrical cable with an arbitrary number of pairs of wires. The objective is achieved in that the Lines with two blocks are used with n wire pairs n transformers, each of which comprises n primary and secondary windings. The primary windings of the transformers are connected the sources and / or recipients of the signals, and the secondary windings of the transformers are connected to inputs / outputs of the switches which can be sequentially, counter or not to connect respective pairs of inputs / outputs to the outputs / inputs. The internal architecture of switches for an odd number of pairs of wires of the matrix elements is determined Belevich dimension n, and to an even number of pairs of wires is determined by the elements of the Hadamard matrix of dimension n. Multiple Wire communication line is connected to the output / input switches. By beneficial technical effects include: reducing crosstalk, increase range and data rate as well as improving and simplifying the production of stealth multiconductor cables.
