<p>A method for optical data transmission and associated routing system. One carrier wave is modulated with the data of a data packet to form a data block, and one or more other carrier waves, having wavelengths different from the first carrier wave and from each other, are modulated with the address of the data packet to form one or more address blocks. The data and address blocks are transmitted simultaneously along a common spatial channel. By assigning multiple carrier waves of different wavelengths to different data packets, several data packets may be transmitted simultaneously along a common spatial channel. Routing systems (34) use passive switches (122) to separate the data and address blocks so that the address blocks can be decoded (24). Encoding an address in several address blocks, with one bit per address block allows a particularly simple address decoding scheme that preserves the simultaneity of transmission of multiple data packets.</p> |
