Abstract:

The active-fault-alarm (AFA) has been developed to achieve fast recovery of various network services, but the false-alarm still exists when applied to 10 Gigabit ethernet positive optical network (10G-EPON) in power grid. 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 experimental results suggest the better performances of the new mechanism and show that the AFA-PP can solve the false-alarm problem efficiently. takes full advantage of the AFA technologies, and allows conducting pre-protection operation in advance. Analytical and
