ABSTRACT:
An optical network broadcasts the same data on a plurality of wavelength channels from a source network to destination network. The network elements of the optical network are configured so as to provide four diversely routed transmission pathways. At the receiving end, one of the plurality of wavelength channels is selected as the primary wavelength channel.
