PROJECT TITLE :
Fully passive resiliency node for optical access [Invited]
A novel resiliency node for access network restoration is presented. Rather than using electrically powered nodes in an otherwise absolutely passive fiber plant, the proposed node is optically fed. The incorporation of energy scavenging mechanisms and optoelectronics with low power consumption guarantee operation at low optical feed levels of ???10 dBm. Feeder protection for optical access is experimentally demonstrated that features a fast switching time of ten.seven ms in interaction with a management plane. Finally we have a tendency to establish choices for self-pumping of the network node through straightforward optical power tapping of feeder and drop signals.
