PERFORMANCE ANALYSIS OF DIFFERENT ERBIUM DOPED FIBER BASED CODIRECTIONALLY PUMPED WDMSYSTEMS OPERATING IN OPTICAL WIDE-BAND

摘要

In this paper, simulation studies of different types of erbium doped fiber amplifier (EDFA) based codirectionally pumped systems, operating in C and L band have been analyzed for wave division multiplexing (WDM), which is in accordance with ITU standards. The natural gain and noise figure (NF) for variable pump powers at 0.03W, 0.06W, 0.12W, 0.18W and 0.24W were obtained. A comparative study of these fiber amplifiers using a figure of merit (FOM), in terms of gain uniformity in the given optical band was discussed.
