Abstract
This paper shows an analytical and numerical method to determine some important parameters associated with Raman- Brillouin hybrid distributed fiber sensors by solving the governing differential equations. It is considered pump depletion caused by all involved effects: Rayleigh, Raman and Brillouin. Solutions are discussed for two important cases, one apply simultaneously spontaneous Raman and Brillouin scattering and another apply Brillouin stimulated and Raman spontaneous. It is demonstrated that sensors length can be maximized in one of the cases, in a good agreement with literature; it is also discussed the implementation of the sensor and its feasibility for both cases.
