10. A system, comprising:
a sensor network comprising a network of multiplexed optical sensors of one or more optical fibers;
a processor operatively coupled to the sensor network and configured to:
receive streaming data in the form of peak readings developed from spectrum data produced by the sensors, the streaming data comprising wavelength and intensity data associated with the sensors;
determine, for a particular fiber, whether a number of the peak readings is the same as, or differs from, an expected number, N, where N corresponds to a total number of sensors of the particular fiber; and
correct anomalous streaming data in response to determining that the number of the peak readings differs from the expected number, N; and
a memory operatively coupled to the processor, the memory configured to store nominal wavelength and intensity streaming data and the corrected wavelength and intensity streaming data in a structured data table indexed by fiber ID and sensor ID.
