    摘要： A method includes receiving a restoration indicator associated with a path that includes an optical cross-connect (OXC). The OXC is reconfigured from a standby configuration to a restoration configuration in response to the restoration indicator. An optical signal received in a first direction at a first wavelength is optically regenerated to produce an optical signal in the first direction at a second wavelength. An optical signal received in a second direction at the second wavelength is optically regenerated to produce an optical signal in the second direction at the first wavelength.

    摘要： An arrangement in a node in an optical communication network has one or more terminals 220 and/or 222 configured to provide local access to the network through the node, and an all-optical routing arrangement 202-204-206-208 configured to route optical signals among optical pathways extending from the node. The optical pathways include inter-node optical pathways (for example, pathways N and/or W) configured to carry optical signals into and out of the node to respective other elements in the network, as well as intra-node optical pathways (for example, pathway E) dedicated to carry optical signals between the routing arrangement and respective terminals so as to provide the local access to the network through the node. Placing the terminals on optical pathways allows redundancy of the terminals to avoid node isolation if a terminal fails, yet is more economical than conventional arrangements requiring a terminal for each pathway into the node.
