More Information
Summary:An ignition system is described, in particular for an internal combustion engine of a motor vehicle, having a laser spark plug, a pump module for supplying the laser spark plug with pump radiation, and an optical fiber device for transmitting the pump radiation from the pump module to the laser spark plug. At least two separate signal transmission devices which each extend at least partially along the optical fiber device, and an evaluation unit, which is designed to act on each of the signal transmission devices with a test signal, to evaluate a response signal of the signal transmission devices which results from the particular test signal, and from the response signal to deduce an operating state of the corresponding signal transmission device, are provided.
