Overvoltage protection for data networks A particular hazard to the networks is posed by overvoltages which can have a direct effect on the data lines. Triggered by distant, near or direct lightning strikes, transient overvoltages can be coupled into the lines and electromagnetic fields, potential differences and lightning currents can form. These can ultimately cause interference that causes a complete system failure. A long-term operational failure and even the loss of important data are among the greatest risk factors. To prevent any damage from occurring in the first place and to ensure the performance of data networks, Citel offers an ideally matched protection concept for Ethernet networks.
