Claim 9:
10. A method for distributed fiber optic sensing (DFOS), the method comprising:
generating first data signals;
generating first sensing signals;
controlling one or more parameters of the first sensing signals at least partially based on a type of the first data signals;
providing each of the first data signals and the first sensing signals to a first fiber optic strand, for transmission by the first fiber optic strand;
generating second sensing signals for transmission via a second fiber optic strand;
providing the second sensing signals to a second fiber optic strand, for transmission by the second fiber optic strand;
receiving, from the first fiber optic strand, scattering signals of the first sensing signals resulting from a perturbation of the first fiber optic strand while the first sensing signals are being transmitted by the first fiber optic strand;
receiving, from the second fiber optic strand, scattering signals of the second sensing signals resulting from a perturbation of the second fiber optic strand while the second sensing signals are being transmitted by the second fiber optic strand; and
analyzing each of (a) the scattering signals of the first sensing signals and (b) the scattering signals of the second sensing signals, to perform DFOS.
