great-capacity and long-distance

With people's increasing demand on communication band width in recent years, optical fiber communication technology, which is high-speed, great-capacity and long-distance, developed so rapidly. With the development of EDFA and the application of chromatic dispersion compensation, the question of loss and chromatic dispersion is no longer a major best clothes blog constraint for Optical Fiber Communication development. However, the high-speed transmission rate make Polarization Mode Dispersion (PMD) as the bottleneck of optical fiber technology wedding dresses form china development. As a result, it plays a important role to study on PMD.The rapid numerical difference recurrence algorithm is used to analyse the nonlinear Schrodinger equation (NLSE) in which the chi hair straightener chromatic dispersion and the nonlinearity act together with Lacoste Polo Shirts. And it is used to study the optical pulse transmission with PMD. The calculated results by using the rapid numerical difference recurrence algorithm are contrasted with the analytical results and the results of the split-step Fourier method (chi hair straightener) and indicate that the rapid numerical difference recurrence algorithm is very accurate and more reasonable. It has been concluded that the new method is scientific and reasonable for the study of light pulse propagation with PMD. Moreover, it is used to study the pulse distortion and the pulse broadening in the optical pulse transmission with PMD .As a result , some valuable curves are obtained to help design the optical transmission system.
