dc.description.abstract Today’s world depending on frequent data communication, optical fiber is the most frequent physical backbone to transferring carrier information and sometimes it is distorted, attenuated and losses of information. Span analysis is the calculation and verification of a fiber-optic system's operating characteristics. This includes items such as fiber routing, electronics, wavelengths, fiber type, and circuit length. Attenuation and nonlinear considerations are the key parameters for loss-budget analysis. Demandable ultra-wideband transmission over the Internet, Transmission techniques is now measured to be very important. Hence, upgrading current RZ- 10Gbps DWDM optical systems with 40 Gbps channels multiplexed with accessible traffic infrastructure we can enlarge the capacity to Terabit/s with minimum advancement tasks. We apply the DPQPSK transmission technique of single light wave channel over optical fiber communication systems. It has capability to double the bit-rate compared to usual OOK signaling techniques. For simulation we apply the block sets of communication and signal processing of the Matlab ™ Simulink. A high-capacity 20 Gbps (2 * 10 Gbps) and 40 Gbps (40*10 Gbps) can be extended from 10Gb/s channels. Theoretical background of the design of the optical DQPSK system is given. Detailed operation and purpose of each component model and its outcomes in Simulink Block sets are explained. Future plane which support DWDM operation to allow Tbps transmission with N x 40 Gbps systems are also draw round. en_US
