الملخص

The main objective of this project is to study the effect of the fiber dispersion in single mode fiber and show how it can compensate. In order to achieve the objectives of the project, we studied and stimulated the phenomenon referred to as group-velocity dispersion (GVD) in Single-Mode Fibers and shown how dispersion of the pulse limits the distance because the receiver must recover an unstable signal. The ability of the receiver to do this varies quite a lot with the design of the receiver itself and with the communication protocol. This casing a signal degradation and make it spreads and broaden along the distant and that lead to reduced the system performance; then shown how we can control and manage this effecting. the OptiSystem Software was used to demonstrate the influence of the (GVD) on Gaussian pulse propagation, and shown how the single was broadened; then compensate of this dispersion and single broaden with Ideal dispersion components. After the most major important factor was set like bit rate equal to 40 GB/S, which correspond to bit duration of 25 ps; and using the default value of 0.5 for “width” of the Optical Gaussian Pulse Generator and the resulting FWHM of the pulse is 12.5 ps.Then calculated the dispersion length which was 2.812km and set it at the fiber properties and disable all the effects except GVD and the project calculated under these values, the obtained result shown that the pulse was broaden (the peak power decreased). Then changed the fiber length to (10 km) and calculated the project the result shown that how the signal broaden and the width of the pulse increased approximately four time; Then added the Ideal dispersion compensation component to the design and set the dispersion parameter to (- 160 ps/nm) and calculated the project; the result shown that how compensation of accumulated dispersion was achieved. In this project, the properties of optical fibers are discussed. When the GVD is considered, and shown how it affected the signal and reduced the system performance and limiting the transmission distant. Compensation necessary. However, dispersion compensation introduces additional loss and complexity to systems. This leads to various system configurations in terms of transmission fibers deployed
