Abstract: Systems and methods are provided for generating a model for detection of seismic events. In this regard, one or more processors may receive from one or more stations located along an underwater optical route, one or more time series of polarization states of a detected light signal during a time period. The one or more processors may transform the one or more time series of polarization states into one or more spectrums in a frequency domain. Seismic activity data for the time period may be received by the one or more processors, where the seismic activity data include one or more seismic events detected in a region at least partially overlapping the underwater optical route. The one or more processors then generate a model for detecting seismic events based on the one or more spectrums and the seismic activity data.

Abstract: The present disclosure describes a network including two levels of switching: a first level including wavelength selective switching via a first type of switching module, and a second level including fiber level switching via a second type of switching module. The two levels of switching allow for maintaining wavelength selective switching between transmission directions while introducing fiber selective switching between network degrees of the same transmission direction. The first type of switching module is configured to transmit and receive optical signals having a first set of wavelengths at a first network degree at a first direction in a node of a network. The second type of switching module is configured to transmit and receive the optical signals from the first type of switching module and route the optical signals at the first network degree to a second network degree in a second direction.

Abstract: A system is provided along a route of a network including a first transponder at a first node and a second transponder at a second node. The system further includes one or more processors configured to detect, in a first waveform measured at the first transponder, a first signature at a first time point, and configured to detect, in a second waveform measured at the second transponder, a second signature at a second time point. The one or more processors may correlate the first waveform and the second waveform, and determine, based on the correlation, that the first signature and the second signature correspond to a same event occurring along the route of the network. Based on comparing the first time point and the second time point, the one or more processors may determine an estimated location of the event.
