A configuration of a switching fabric based on semiconductor optical amplifiers (SOAs) is presented. This configuration has an output noise (ASE) almost independent of the number of input/output ports of the switch, allowing more fabrics to be cascaded. The large gain required by each SOA can be overcome by distributing the gain over several stages. © 1997 John Wiley & Sons, Inc. Microwave Opt Technol Lett 16: 364–368, 1997.
