In this study, the effects of erbium-doped fiber amplifier (EDFA) on Brillouin and Rayleigh power spectrums are observed. For this analysis, Brillouin Optical Time Domain Analysis (BOTDA) configuration is used with an 18 km single mode fiber cable as the fiber under test (FUT) and 1550 nm band is utilized for the incident wave and EDFA. The scattered back wave is observed with both an RF spectrum...
In this study, fiber lengths of each stage of the three stages L band erbium doped fiber amplifier (L-EDFA) and the pump laser power are optimized to achieve the maximum gain, the minimum noise figure and the minimum gain ripple. It is obtained on an average 34.7–37.1 dB gain, 6.28–6.0 dB noise figure, and 2.13–2.28 dB gain ripple along all L band for the 980–1480nm pump wavelengths, respectively.
