The architecture of optical time domain multiplexed add drop nodes in a meshed network

Future optical networks will be meshed and transparent. Going towards high-speed optical networks with data rates above 40 Gbit/s per wavelength, optical time domain multiplexing (OTDM) techniques will be applied. Such OTDM networks give rise to a couple of challenges concerning the architecture of add-/drop nodes and optical cross connects. We present a concept for an architecture of an OTDM add-/drop multiplexer and show potential applications. First experimental results proving the feasibility of the OTDM network technology are presented.
