Effect of EDFA power on Brillouin power spectrum
2017 4th International Conference on Electrical and Electronic Engineering (ICEEE), 2017 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.

Intrinsic multichannel power control in cascaded power-equalizing erbium-doped fiber amplifiers [PDF]
, 2000 We numerically investigate the performance of a cascade of four-channel power-equalizing reflective erbium-doped fiber amplifiers (EDFAs). The EDFAs reflect different channels at different points so that different channels interact with partly different ...
