Abstract
The invention relates to a time division and wavelength division multiplex optical switching node for use in an optical communications network (), which node combines a set of time division multiplex packets (---i) into a wavelength division multiplex packet () to form a composite wavelength division multiplex packet, in particular by conferring on each time division multiplex packet (---I) a respective appropriate multiplexing wavelength (λ, . . . , λi), for example a wavelength specific to each time division multiplex packet. The invention has applications in high bit rate optical networks in particular, in which it offers versatility and transparent use of the different multiplexing modes.
