Reconfigurable interconnection in optical switching fabrics with wavelength converters

The high degree of flexibility expected from future networks can be provided by switch architectures which combine a wide range of functionalities by operating in different dimensions, namely time, space, wavelength, suitably explloited by reconfiguration capability. Architectures design are here proposed based on programmable optical backplane to implement reconfigurable interconnections in switching fabrics with wavelength converters. Complexity comparisons are presented and cost of programmability evaluated.
