The module is designed to protect gigabit LANs against the effects of overvoltages and lightning discharges. It is built on the basis of a multi-layer PCB with carefully designed printed circuits. Along with durable components of small dimensions and dedicated 6th category RJ-45, ensure excellent data transmission quality and high surge currents resistance. Each conductor of the LAN cable is individually protected by a protective component with a 2kA (8/20uS) impact strength. In combination with uniform PCB tracks of very high thickness gives a product with stable properties of surge protection.
