Analysis of SNR Enhancement in with FBG WDM Optical Systems using Multi Stage Fiber Amplifier

In this we have Design an advanced dispersion compensation system for high bandwidth communication links also Use of FBG or hybrid grating schemes for optical medium. EDFA can be utilized in the high-limit and rapid optical correspondence framework. The utilization of EDFA is exceptionally useful to manage the issues of low affectability of recipients and short transmission separations attributable to an absence of OEO repeater. In the event that light vitality as of now exists inside the 1500–1600 nm band, for instance, because of a flag channel going through the EDF, at that point this fortifies the rot procedure (alleged animated outflow), bringing about extra light vitality. A pumping signs can co propagate with a data flag or it can counter proliferate. In this way, if a pump wavelength and a flag wavelength are all the while engendering through an EDF, vitality exchange will happen by means of the Erbium from the direct wavelength to the flag wavelength, bringing about flag enhancement. A wavelength a long way from the outflow top around 1530 nm needs to enhance the intensification attributes of the L-band and C-band EDFA.
