Search for: [Description = "The backbone networks evolution to high\-speedDWDM networks generates new problems for switching. Thisfunction element must be also based on optical technology. Forlarge capacity this cannot be realized by a single matrix, butby multistage switching networks. In the paper three types ofoptical matrices have been described\: fiber switch FX, wave\-length fiber switch WSX and wavelength interchanging fiberswitch WIX. Based on these matrices, four switching networkconstructions were considered. The connection properties ofthese switching networks were evaluated, determining the elec\-tronic equivalent switching network for which these propertiesare well known."]
