Abstract
An optical switch includes an optical transmission path having an optical transmission medium, an input-side end and an output-side end. A radiation source is associated with the input-side end for emitting a primary optoelectronic signal being coupled into the transmission path. A reflection device is associated with the output-side end for receiving the primary optoelectronic signal and converting the primary optoelectronic signal into a secondary, modulated optoelectronic signal being reflected and coupled back into the transmission path. A receiver is associated with the input-side end of the transmission path for responding to the secondary, modulated optoelectronic signal to perform an electronic switching operation.
