In the worst-casescenario, voltage surges, causedby galvanic, capacitive or inductivecouplings in data cables, can destroyIT and telecommunicationsequipment within a network. Toavoid such failures, suitable protectionmeasures must be undertaken.Due to a wide range of current information,telecommunicationand measurement systems, the selectionof the right surge protectiondevice is often difficult in practice.The following factors must be takeninto account:• The connection system of theprotection device must matchthe device to be protected.• Parameters such as the highestsignal level, highest frequency,maximum protectionlevel and the installation environmentmust be taken intoaccount.• The protection device may onlyhave a minor impact ontransmission route, such as attenuationand reflection.Protection principleA device is only protected againstsurges if all energy and data cablesconnected to the device areintegrated into the equipotentialbonding system at the lightningprotection zone transitions. OBOBettermann offers a completerange of tried-and-tested, highlyfunctional and reliable data cableprotection devices for all standardtelecommunication and informationtechnology systems.TBSOBO41
