Minimizing Crosstalks in Unshielded Twisted-pair Cables by Using Electromagnetic Topology Techniques

Crosstalk reduction is analyzed for a reconfigured category-five cable network using electromagnetic topology-based simulation. The reconfigured network results in a marked reduction in inductive near-end crosstalk for the unshielded twisted-pair cable network. Analyses show that half-loop shifting of the generator-pair wires placed next to the receptor is the most effective way to control the ...

Experimental Study of Electromagnetic Interference (EMI) on PCBs and Cables enclosed in Complex Structures

Electromagnetic Losses in Magnetic Shields for Buried High Voltage Cables

The electromagnetic losses and shielding efficiency of shields for a buried three phase high voltage cable are studied for several shielding configurations. The shields are U-shaped gutters covered with plates, and the power cables are positioned either in trefoil or in flat configuration. The shielding efficiency and the losses are compared for shields with the same geometry but several shield...

EMC’04/Sendai ELECTROMAGNETIC INTERFERENCE AMONG CABLES AND INTERCONNECTIONS : APPROXIMATIONS THROUGH HIERARCHICAL GRAPHS

Electromagnetic topology was introduced a few decades ago in order to bring some rules in analysing EMC of very large systems through a fluence graph of electromagnetic interactions. Establishing these graphs was made possible from application of the so-called "good shielding approximation". At cable or track level, such a procedure is investigated in this paper. Other approximations are introd...

Electromagnetic coupling of twisted pair cables

Increasing deployment of digital subscriber line (DSL) technology operating in the long wave, medium wave and sometimes short wave frequency ranges, has raised the question of how such systems interact with rival radio frequency sources and equipment. Two of the major standards bodies in the field, ITU and ETSI, imposed by the standardization of such promising technologies like ADSL, SHDSL and ...
