A signalling experiment for the optically switched data transmission of a 140 Mbit/s FSK modulated carrier is demonstrated. Optical control pulses determined in the frequency and time domains are generated and routed to an optically controlled bistable gate. The signalling, controlling, and switching remain completely in the optical domain.
