ABSTRACT:
An optical telecommunications system node terminates a plurality of optical cable routes. Each of the optical cable routes includes a traffic route and a restoration route. The node includes a plurality of traffic wavelength division multiplexers and a plurality of restoration wavelength division multiplexers. A traffic wavelength division multiplexer is connected to each traffic route and a restoration wavelength division multiplexer is connected to each restoration route. The node includes a plurality of optical cross connect layers. Each optical cross connect layer includes a connection to each of the traffic wavelength division multiplexers and to each of the restoration wavelength division multiplexers.
