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)
