  • Optical interconnection for traffic between a pair of DWDM rings
    Patent number: 7356258
    Abstract: Apparatus for diversely routing optical wavelengths across a point-to-point subnetwork. An optical network includes a first optical ring having at least first, second, and third nodes adjacently positioned; a second optical ring having at least fourth, fifth, and sixth nodes adjacently positioned, pairs of optical fibers link the adjacent nodes; a point-to-point subnetwork having at least first, second, third, and fourth optical fibers optically coupling the first and second optical rings. The first node is configured to route working bands across the first optical fiber to the fifth node and to route a copy of the working bands to the second node. The second node is configured to route either the copy of the working bands or a select subset of the copy of the working bands across the third optical fiber to the fourth node.
