Abstract
Systems and methods for performing protection switching in a passive optical network are provided. When a fiber cut is detected, control and management plane applications are not immediately informed. A rapid re-registration procedure is instigated upon detection of a fiber cut event. This allows multiple optical network units to re-register quickly without restarting control and management applications.
