Electromagnetic interference impact on communication tests

With the widespread distribution of information technology equipment in today's society, higher reliability is required for transmission systems. As a result, service interruption involving even temporary voltage spikes is of critical importance. Keeping this in mind this paper presents the cause, effect and solution of electromagnetic interference on telecommunication, data and computer communication by incorporating EMI control measures at various levels of equipment manifestations. The paper deals also with the lightning electromagnetic pulse (LEMP) effects on systems, cables and various subsystems of a typical ground based networking system.
