摘要：In the era of telecommunication industry, fiber optic communication plays an important role and we alsosay that the fiber optics communication is the backbone of telecommunication industry. With the development ofoptical networks and the use of Wavelength Division Multiplexing (WDM) technology, a new and a very crucialmilestone is being reached in network evolution. To upgrade the system to handle voice and data traffic is veryexpensive and hence the need for the development of an intelligent all-optical network. Such a network will bringintelligence and scalability to the optical domain. DWDM (Dense Wavelength Division Multiplexing) is a technologyin fiber optic communication which carries the multiple wavelengths into a single fiber to communicate to the end userswith specific wavelength. When multiple wavelength transmitting over a single optical fiber these wavelength suffercross talk due to low frequency spacing and the cross talk of wavelength affects the BER(Bit error Rate) at the receiverwhich determines the performance of the system. Quality factor is also a key component in the optical fiber to analyzethe system performance of the of the DWDM system. As it is known fact that as the number of user increases systemperformance decreases. So there are three windows at which attenuation is minimum but here the author has done theresearch on two wavelengths, 1310nm and 1550nm.The effect of increasing length of the fiber and increasing data rateshas been analyzed in the research and according to that the concept of Soliton pulses has been clubbed together so as tomake the new effective system which can support higher data rate. The author has simulated and analysed differentscenario, which includes the data rates at 320Gbps, 400 Gbps, 560 Gbps at different lengths of 40 km, 50km, and80km. So the system has been designed and simulated on the optical software which is supporting 640 Gbps for 70kmlength.KEYWORDS
