Abstract

In this paper, we have analyzed gain bandwidth product through gain flatness in EDFA for dense wave length division multiplexed system. The system consist of four channel DWDM with varying wavelengths of optical fiber from 1530 to 1560 nm and by changing the noise for each amplifier to achieve the quality factor and noise figure of both the amplifiers. In this article, we used the frequency spacing of 2 GHz of the DWDM system and at different lengths i.e. for EDFA is 22 m at 60 km distance. In this method, for EDFA, we get the maximum quality factor at 1545 nm of wavelength.
