| Abstract | Increased channel capacity of optical transmission system is obtained either by increasing the bit rate of transmission or by using the technique of wavelength division multiplexing (WDM). In long distance communication, higher launched power is required to achieve the required signal to noise ratio. But with the increased launched optical powers, bit rates and the number of wavelength channels, the nonlinear optical effects have been increased. Also, at high bit rate, group velocity dispersion (GVD) limits the transmission distance. Cross-phase modulation (XPM) is an important nonlinear impairment that causes interference through intensity-dependent phase shifts between two optical fields in optical networks using WDM. This effect limits the allowable input optical power and system capacity. The XPM effect with SPM and GVD degrade the system performances significantly. In this research work, a detail analysis have been done to find the mathematical expression for pulse broadening factor by solving nonlinear Schrödinger equation (NLSE) considering the effects of XPM with SPM and GVD in WDM system. By using this mathematical expression, pulse broadening factor has been visualized. The results are evaluated at different bit rates, different input power and varying transmission distance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
