Dispersion Compensation and Power Optimization using Multi Stage SOA in Association with DCF and FBG

Now a day�s optical communication is a popular technique to transmit the data. In daily life we share our useful data by using optical network. We face a common problem that is dispersion and power. Dispersion Compensating Fiber (DCF) and Fiber Bragg Grating (FBG) are widely used dispersion compensation techniques for optical communication systems. In proposed work we have Fiber optic frameworks are of the basis to advanced correspondence systems. The high transfer speed and information rates given by fiber optics can genuinely be used by work of WDM (wavelength division multiplexing) procedures. The WDM framework can take into account a superfluity of incorporated broadband administrations consolidating voice, information, video, mixed media administrations and VAS (Value Added Services). WDM framework long broadly utilized as a part of huge separation lines experiences issues, for example, a scattering and weakening which comes about corrupted framework execution. Scattering remuneration and optical power enhancement are basic parameters in WDM frameworks. This work is about the use of multistage SOA (Semiconductor optical Amplifier) framework to increase control and reduce scattering and accomplish higher SNR (Signal Noise Ratio) .It is additionally basic that by position of EDFA pre and post FBG, consider a request of greatness increment in SNR and accomplish Phenomenal DC (Dispersion Compensation) in WDM frameworks
