—We are proposing a new optical access network architecture using PLZT 10 nsec high-speed optical switches, called Active Optical Network (ActiON). Our architecture can increase four times the number of subscribers as well as double the distance between OLT and ONUs than GE-PON. Moreover, a user can establish secure communication in ActiON. Because ActiON(More)
An active optical access network architecture with our newly developed PLZT ((Pb, La) (Zr, Ti)O 3) high-speed optical switch is introduced, with a view to realizing the next-generation high capacity scalable access network. This system is developed based on the latest IEEE standard of PON (10G-EPON; IEEE802.3av) in consideration of the coordination with(More)
