Abstract
The Dense Wavelength Division Multiplexing (DWDM) is a transmission frame network in optical communication. In this the light signals are utilized to transmit data of various frequencies at same time. DWDM plays a role in sending and receiving data through the existing fiber multi-channel communication system. This provides a practical method for increasing the system's limit. In this method fiber communication is used to transmit and receive more data over larger distance. The frequency of the signals ranges between 300GHz to 3000THz. The usage of Dispersion compensates fiber (DCF) can totally compensate for dispersion of 32 channel DWDM. DWDM is a network that allows us to increase data rates without having to replace the network system. Our MATLAB software will allow us all to modify signal consistency, power signal, noise signal, average BER and SNR and Q-factor in DWDM modulation in the 32-channel simulation process. The network's capacity is growing, with the sole change occurring at the receiving end. In order to desire the company clients to offer buyers with many types of assistance that allows us to boost data, we have DWDM this signal is simulated and optimized by reducing to 50km through amplifier.
