    摘要： In today's reconfigurable optical add/drop multiplexer (ROADM) based optical node, ROADMs multiplex (and demultiplex) colored optical signals to form wavelength-division multiplexed (WDM) signals. Transponders connected to the ROADMs' add/drop ports convert noncolored optical signals to colored optical signals (and vice versa). Dedicating transponders to given ports degrades the node's ability to route around network failures. Example embodiments of the invention include an optical node and corresponding method for routing optical signals within an optical node that compensate for this inflexibility. The optical node may include two ROADMs to transmit respective WDM signals onto at least two internode network paths and a routing module that can direct channels of the same wavelength along different internode network paths. Advantageously, a transponder may transmit (receive) different signals at the same wavelength to (from) different network node interfaces within the optical node, thereby improving the optical node's ability to route around network failures.

    摘要： A system and method for designing and constructing optical networks is provided. The system comprises: a server, and interactive software program residing on the server, an interactive input device—capable of accessing the interactive software program residing on the server, and a communication network—used to connect the interactive input device to the server. The method comprises: entering network topology information and service demands for a plurality of nodes into the interactive software program residing on the server, having the interactive software program determine the required optical equipment for the nodes, and ordering the required optical equipment for the nodes using the interactive software program.
