Abstract
It is an object of the invention to provide a network topology for OCDM signals. Coding splitters combining both coding and splitting functions are provided. The coding splitters themselves can be made from cascaded Mach Zehnder filters which are located somewhere in the network and which can be integrated using planar waveguide technologies. Each OCDM transceiver as well as the network is connected to the splitter via a pair of fibers for the two transmission directions. This set-up has the advantage that the same splitter can be used for both directions to and from the transceivers on one side and to and from the network on the other side.
