dc.description.abstract	Optical ﬁber are used for high capacity system compared to electrical mediums and this high capacity is linked to wavelength division multiplexing system so optical ﬁbers are employed to transmit data, voice and other services in form of light pulse between the source and destination. WDM systems have the prospective to transmit several multiple signals at the same time. But the light signals reduce in intensity and optical pulses broaden when they travel a long distance inside the ﬁber. So it is vital to minimize the dispersion and amplify all the light signals at same time after a certain interval of light propagation to recover the original signal. InthisthesistheperformanceanalysisofdiﬀerentchannelsofDWDMnetworkatdiﬀerent parameter is done on the basis of ﬁber bragg grating and erbium doped ﬁber ampliﬁer as dispersion compensation and ampliﬁcation mechanism using opti system software. Here ﬁrst DWDM network without EDFA is analyzed and observed, the signal Q-factor degrades as bit rate increase and secondly DWDM network using erbium doped ﬁber ampliﬁer has been investigated and from result erbium doped ﬁber ampliﬁer improve the transmission distance and have great impact on DWDM network. DWDM networks also suﬀer from dispersion and to compensate this dispersion ﬁber bragg grating is used and the system performance increase by using Erbium doped ﬁber ampliﬁer and Fiber Bragg grating. And ﬁnally the dispersion and attenuation eﬀect on the DWDM network is analyzed with diﬀerent ﬁber length at diﬀerent transmitting power, data rate , channels in DWDM network using ﬁber bragg grating and erbium doped ﬁber ampliﬁer . It is observed that one can easily take DWDM for new deployment for a given distance, data rate, transmission power and capacity especially for campus and huge private and public service that needs long haul high traﬃc network.	en_US
