Abstract :
After the initial problems affecting the transmission of data services at bit rates of 100+ Mbit/sec along twisted-pair (TP) cables had fully been solved through the introduction of state-of-the-art technologies for the production of cables, it became quite clear that-besides the parameters specific to the transmission technology-still other parameters had to be taken into account in order to be able to proceed from lab-type units to proven systems which are suitable for everyday operation by end users. In this connection, the so-called electromagnetic compatibility (EMC) is of crucial importance for these systems. EMC means, on the one hand, that running systems do not disturb the function and/or operation of other devices and systems, and, on the other hand, that such systems are not disturbed either by the operation of different devices and systems. The article reviews how cable manufacturers, designers and end-users can exactly test the influence of cable technologies on the EMC characteristics of systems without, however, having to use a large number of measuring devices
