Researchers at Siemens, in collaboration with partners at BT and the Technical University of Eindhoven, have develop an extremely fast optical switch known as a TD-OADM (Time-Domain Optical Add-Drop Multiplexer) that enables the transmission and routing of diverse data elements in a single light wave length through the network. Conventional optical switches can only direct complete waveguides. Over a two-year period, Siemens researchers collaborated with workers from the COBRA Institute of Eindhoven Technical University (Netherlands) and BTexact...
