Abstract
A broadband surge suppression module having an optical coupling channel includes a surge protection circuit unit for eliminating or limiting a surge signal from an input digital signal, a light-emitting circuit unit for receiving an output signal of the surge protection circuit unit, converting the output signal into an optical signal, and transmitting the optical signal, a light-receiving circuit unit for receiving the optical signal from the light-emitting circuit unit, a signal restoration circuit unit for restoring a digital signal from an output signal of the light-receiving circuit unit, and a module casing unit for allowing the surge protection circuit unit, the light-emitting circuit unit, the light-receiving circuit unit, and the signal restoration circuit unit to be located therein, the module casing unit being formed to penetrate through an electromagnetic shielding wall for protecting a control system.
