Daniel C. McCarthy, Senior Editor/Special Projects

In today's synchronous digital highway and SONET networks, most switching occurs electronically. In dense wavelength division multiplexing (DWDM) systems, remote switching still is perceived largely as a goal. Most current DWDM point-to-point systems rely on manual patching of optical connections to provision services across the network. With its TransXpress optical service node, Siemens Information and Communications Networks Group is hoping to change all of that. The TransXpress supplants manual patch panels and enables DWDM point-to-point links to be tied into a real optical network....Read full article
