Japanese Patent JP2000503192
Kind Code:
A
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 an optical transmission line in a signal path has failed, the controller will re-route the signal path through a spare, or protect component. Alternatively, the controller can re-route the signal path through a frequency translator and another optical transmission line.
