Method for optical time division multiplex transmission via an optical waveguide of a switching system. Between system devices capable of transmission and/or reception which are connected to the optical waveguide, transmission of control signals, which set such light systems, and of subscriber information is provided. In the pulse frame defined by frame identification signals, a first block of time slots serves to transmit the control signals and a second block of time slots serves to transmit the subscriber information. Each transmission-capable system device contains a counter or clock in order to allocate a transmission time slot to the transmission-capable system device concerned. The transmitting system device occupies the system device designated to receive the subscriber information by transmitting the address of this system device in the transmission time slot, where this designated system device is set, e.g. is switched to a different switching state. The frame identification signal (RK1, RK2) contains short light flashes whose intensity is significantly greater than the maximum intensity of the subscriber information and the control signals, the light flash in each case resetting the counter or clock in the system devices to its initial state. <IMAGE>
