Abstract
A system is provided for initiating a blasting cap wherein pulsating light energy is converted to electrical energy. An optical coupler couples the source of energy to a remote firing arrangement to transfer the generated pulsating light energy to the firing arrangement. An electrical connection connects the firing arrangement to an ignition resistor in a detonator. Thus, the generated light energy is converted to electrical energy and is transferred to the ignition resistor, the transferred electrical energy being the firing energy for the ignition resistor.
