Rayleigh scattering characterization of a low-loss MgO-based nanoparticle-doped optical fiber for distributed sensing

We present the fabrication and characterization of a low-loss enhanced backscattering fiber, having core doped with MgO-based nanoparticles (MgO-NP), for distributed sensing application. The fiber has scattering increment 48.9 dB two-way attenuation 14.3 dB/m; these are largest Rayleigh paired lowest losses this type fiber. In work, we provide thorough performances, their impact on networks, using scattering-level multiplexing where 2.4 – 4.0 times extension length can be achieved.
