Abstract: A transport management system receives a request for a planned interruption in an optical network, and identifies transport equipment of the optical network affected by the planned interruption. The transport management system selectively sends a notification, from the network device, the identified transport equipment affected by the planned interruption, including a scheduled time of the planned interruption and a duration associated with the planned interruption, where the notification enables the notified transport equipment to buffer data to be transmitted on links affected by the planned interruption for the notified duration of the planned interruption.

Abstract: An optical network is configured to optimize network resources. The optical network includes multiple optical nodes, light paths between the multiple optical nodes, and a network monitoring device. The network monitoring device monitors the optical network to identify a failure in the optical network. When the failure is a fiber failure, light paths are re-routed around the fiber failure while maintaining the required bandwidth for the optical network. When the failure is a transponder card failure within one of the multiple nodes, a floating spare card may be provisioned to service a particular light path associated with the transponder card failure. When the failure is a node failure, transponder cards in some of the multiple optical nodes are provisioned to reconfigure some of the plurality of light paths to route traffic around the failed node.

Abstract: In some implementations, a device may transmit communication data to a transceiver via an access fiber optic cable. The device may determine that fiber sensing is to be performed for the access fiber optic cable. The device may cease transmission of the communication data for a predetermined time period. The device may generate an optical pulse after ceasing transmission of the communication data. The device may transmit the optical pulse to the transceiver via the access fiber optic cable. The device may receive, prior to expiration of the predetermined time period, a reflected signal from the access fiber optic cable based on the optical pulse. The device may analyze the reflected signal to generate sensing results. The device may perform one or more actions based on the sensing results.
