Abstract :
We propose and demonstrate a seamless maintenance and protection scheme based on remotely reconfigurable remote node. Protection for fiber failures and a centralized optical time-domain reflectometry test for preventive maintenance can be achieved within 90 ms by using instantaneous optical powering at the central office, while maintaining the passive nature of the passive optical network.
