Modelling of Rayleigh backscattering in plastic optical fiber

The Rayleigh scattering coefficient within plastic optical fiber (POF), which is also called turbidity, has been investigated and parameters affecting the level of turbidity have been located and discussed. The Rayleigh attenuation model has been built on turbidity and has been verified by comparing with published data. Disparities between the model and published data have been discussed. The Rayleigh backscattering model based on turbidity and fractional recapture coefficient within the fiber has been built and the dependence of the total backscattered optical power on wavelength has been discussed.
