Data Line Surge Protection Products


Data communications lines and current loops are the life blood of highly integrated systems and networks, which are susceptible to failure from even low-level transient activity, are often exposed to high-level transients such as lightning. Protecting these circuits is another key element of the Optimal Protection Network.
