Distributed sensing, based on Rayleigh scattering or arrays of reflectors, can be extended as a multi-fiber, multi-sensor technique by using multiplexing features. Current research has overcome the time-and wavelength-division multiplexing, that has represented the golden standard for fiber Bragg gratings. In this work, we introduce novel domain that allow "parallel" multiplexing applied to distributed sensors, and are routed in the use of specialty fibers. The use of fibers doped with MgO-doped nanoparticles, as well as polymethyl methacrylate fibers, enables new domains for multiplexing, that are discussed in this work. Scattering-level, polarization, and sensitivity based multiplexing are discussed and applied to strain, temperature, and refractive index measurements.
