Abstract
A broadcast and select ring network for optical WDM communication includes two parallel fiber rings () carrying traffic in opposite directions between nodes (; A, B, C, D). The nodes comprise on their receive side selecting means such as a cross connect device () or similar means allowing a flexible selection of the wavelength channels which are to be received by each node. Thereby, any WDM channel in the rings can be selected and received in the nodes. For example, all nodes can receive signals in the same channel for e.g. set up or reconfiguration purposes. Furthermore, the number of receivers in a node can be small but still all channels can be received. The number of transmitters in each a node can also be small since every transmitter can reach every receiver.
