Abstract :
A photonic ATM switch has been developed with frequency division multiplexed (FDM) output buffers. The switch has a broadcast-and-select network architecture using fixed-frequency-channel transmitters and a passive star configuration. Although it has a simple structure, it can provide either broadcast or multicast switching. The output buffers, which resolve cell contentions, are comprised of fiber delay lines that can easily handle signal speed of over 10 Gb/s. Experimental switching of two-multiplexed 10 Gb/s cells with a 2.8-dB power penalty demonstrated high-speed switching
