Abstract
The present invention relates to an optical switching device for WDM systems based on multi-frequency lasers and optical couplers. A router/switch mapping of IP (or other protocols) subnets or addresses to an optical channel instead of a physical interface. Another embodiment of the invention implements the mapping directly at the source where the data transmission originates. The invention allows integration of WDM in the routers and switches, and ultimately in the information source. As a result, unnecessary opto-electrical conversion steps and physical interfaces are eliminated.
