Abstract
Analytical expressions of equivalent noise figure and other noise characteristics of distributed fiber Raman amplifier (DFRA) are derived, for the first time to the knowledge of the authors, including difference in polarization state and attenuation coefficients between pump and signal light(s) as well as multiple-wavelength pumping. Accordingly, their impact on DFRA performance and optical signal-to-noise ratio improvement ((Delta) OSNR) of a cascaded DFRA+EDFA is investigated. With increasing DFRA on-off gain, (Delta) OSNR increases first linearly and then logarithmically, leading to saturation. Results of this work agree well with existing work. Based on these results, some guidelines on DFRA design is proposed.
