| Abstract | The effect of polarization mode dispersion (PMD) imposes serious restriction on the allowable distance and ultimate hurdle for the massive deployment of multi-gigabit transmission rate in an optical communication system. An analytical approach is presented to determine the impact of signal phase distortion due to PMD in a single mode fiber (SMF) on the bit error rate (BER) performance of an optical continuous phase FSK (CPFSK) transmission system with MZI based direct detection receiver. The probability density function (pdf) of the random phase fluctuation due to PMD and group velocity dispersion (GVD) at the output of the receiver is determined analytically. Based on the pdf of the random phase fluctuation the BER performance results are evaluated at a bit rate of 10 Gb/s fiber with dispersion co-efficient Dc=15 ps/km-nm for different values of the mean differential group delay (DGD). The computed results show that the direct detection CPFSK system suffers a significant amount of power penalty due the effect of PMD at a bit rate of 10 Gb/s. At a modulation index of 0.5, the penalty at a BER of $10^{-9}$ is found to be 0.5 dB, 1.25 dB, 2.35 dB and 4.0 dB when the mean differential group delay (DGD) is 10 ps, 20 ps, 30 ps and 50 ps respectively for a fiber length of 100 km. At modulation index of 1.0, the penalty is approximately 5.25 dB for a mean DGD of 40 ps. The penalty is more significant at higher modulation index and bit rate |

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.
