The RJ45 series communication electricity wells up the protector is wells up protector's modular design based on the IEC communication electricity to use in the computer network signal, communication lines' electricity welling up the protection product, the product connection form for the standard RJ45 quartz attachment, may protect 1 pair of /2 pair of /4 pair of communication lines. Installs the maintenance great convenience. The reaction time is the picosecond level, and protects fully uses the newest semiconductor device's equipment, is most suitable in view of the different line choice.
