Abstract: A device may provide a first optical signal to an optical fiber network via a live fiber cable, the first optical signal including a distributed fiber optic sensing optical signal, and may receive, from the optical fiber network, a second optical signal, based on the first optical signal and via the live fiber cable. The device may determine whether a vibration event associated with the live fiber cable is detected based on the second optical signal, and may perform one or more actions based on whether the vibration event associated with the live fiber cable is detected.

Abstract: A device can include a first component to receive, from a first network device, a first upstream optical signal. The first upstream optical signal can be associated with a designated time slot of the first network device. The device can include a second component to receive, from the first component, the first upstream optical signal. The second component can split the first upstream optical signal into a second upstream optical signal and a third upstream optical signal. The second component can provide, to a second network device, the third upstream optical signal. The third upstream optical signal is not associated with the designated time slot of the first network device.

Abstract: A monitoring system connected to a network may receive a request from a user device over the network to monitor a fiber cable. A fiber sensing device may connect to the monitoring system, may communicate messages with the monitoring system, and may connect to the fiber cable. The fiber sensing device may receive an instruction from the monitoring system to begin a monitoring function for the fiber cable, and may provide a first optical signal to the fiber cable. The fiber sensing device may receive, from the fiber cable, a second optical signal, based on the first optical signal, and may detect a risk to the fiber cable based on the second optical signal. The fiber sensing device may send an alert about the risk to the fiber cable to the monitoring system, and the monitoring system may send the alert over the network to the user device.
