Abstract
A system and method for photonic facility and line protection switching in an optical network to permit fault tolerant operation. The optical network comprises components whose operation is monitored by a controller. If the controller determines a component in a signal path has failed, the controller will re-route the signal path through a spare, or protect, component.
