Abstract

A novel architecture with full-duplex direct communications (FDDC) between any two ONUs for optical access network is proposed in this paper. By designing combination switch ingeniously, the architecture is finished to realize FDDC between any two ONUs in wavelength division multiplexing passive optical networks. By utilizing interconnected optical fibers between ONUs, the network has achieved three-level protections (feeder optical fiber protection, distributed optical fiber protection and interconnected optical fiber protection). By constructing expansion module, the network can be flexibly expanded and optimized, and the CapEx and OpEx of network can be greatly reduced. Finally, by the simulation and analysis, the effectiveness of the proposed architecture is demonstrated.
