Abstract

An arrangement is specified in which a binary word is asynchronously transmitted in an optical signal and which is represented by high and low intensity levels is supplied to a plurality of optical inverting devices; the optical signals output by the inverting devices, which have mutually different wavelengths, are supplied as aggregate signal to a wave-length-selective delay device; when the desired binary word is present, the individual binary characters at the input of a detection device become superimposed to form an intensity level which is lower than a high intensity level caused by a single inverting device. Other embodiments relate to the changeability of the wavelength of the optical signals output by the inverting devices and the double inversion of the optical signal in individual signal branches. <IMAGE>
