To solve this problem, an active fault alarm based pre-protection （AFA-PP） scheme in 10G-EPON system for power grid is proposed in this paper. The AFA-PP scheme takes full advantage of the AFA technologies, and allows conducting pre-protection operation in advance. Analytical and experimental results suggest the better performances of the new mechanism and show that the AFA-PP can solve the false-alarm problem efficiently.展开更多

The measured results show that this circuit can recover clock and data from each 10 Gbit/s burst-mode data packet within 5 bits, and the recovered data pass eye-mask test defined in IEEE standard 802.3av.展开更多
