A reliable dual-fiber ring-tree wavelength-division multiplexing optical access network architecture is proposed in this paper. On the one hand, due to the use of differential phase shift keying modulation, triple-play service including point-to-point service and broadcast service is realized. On the other hand, the wavelengths can be allocated dynamically(More)
A dual-polarization higher order mode substrate integrated cavity (SIC) antenna array operating in Ka band is proposed. Cross-shaped radiating slots are employed to achieve the dual polarization performance. An 8×8-elements array is designed by using three layers of double-side printed circuit broads (PCBs), which is composed of two layers feeding(More)
We propose a wavelength-reuse wavelength-division multiplexing semipassive optical access network architecture with ring topology. Two access rings are controlled by one central office. The system capacity, as well as the network cover area, can be doubled with this proposal. When fiber failure occurs, the corresponding switches in remote nodes change to(More)
A ring-based wavelength division multiplexing access network is presented in this paper. By introducing a novel alternate transmission mode, the network can optimize the optical power received by each node. By using ring topology, the central office can provide full protection in the case of both singleand double-fiber failure. It can make the number of(More)
