Abstract
A switch for an optical transmission network using wavelength division multiplexing has pinput ports receiving pwavelengths and first switching means for switching the pwavelengths to poutput ports, qinput ports receiving qbands of wavelengths and second switching means for switching the qbands to qoutput ports, rinput ports receiving rgroups of bands and third switching means for switching the rgroups of bonds to routput ports. The three switching means consist of a single switching matrix adapted to couple any of the p+q+rinput ports to any of the p+q+routput ports. This single-matrix architecture can switch all the granularities at the same time, which facilitates reconfiguration as a function of evolution of the traffic to be switched.
