【Abstract】 Optical packet switching can conquer the electronic bottleneck that confines the development of optical networks. The switching granularity of optical packet switching is smaller than that of optical circuit switching or optical burst switching. The principle and key technologies of optical packet switching is introduced in this paper. The research results are shown, including the generation of single-sideband subcarrier label, contention resolution, all-optical clock recovery and 2R regeneration.更多还原
