Optical Code Division Multiple Access (OCDMA) has bright future in communication because of its faster speed, efficiency, security and unlimited bandwidth. A Zero Cross-Correlation (ZCC) code is analyze to reduce the impact of system impairment and Multiple Access Interference (MAI) in Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) system. The effective OCDMA system is the choice of efficient address codes with good or almost ZCC properties for encoding the source. This paper focusing on the study of ZCC code design with code most important zero cross-correlation property and analyze its performance compared using different two photo detectors. The result shows that ZCC code gives bit error rate of 10-9 at distance of 60km for 10 number of user and 5 numbers of user with data rate of 10Gbps at 100km respectively with different wavelengths at different windows. It also shows using the ZCC code leads to simplicity in system design, cost effective, reduce the MAI and PIIN noises through the zero cross correlation property. The simulation result analyzed in optisystem 13.0. The result indicates that the established system not only preserves the capability of suppressing MAI, but also improves bit error-rate performance as compared to the conventional coders.Keywords

In order to upgrade the overall system performance of optical communication system affected by dispersion, several dispersion compensation techniques are proposed and analyzed. Fiber Bragg Grating (FBG) is most advanced technique for dispersion compensation in optical fiber communication system. In this paper, FBG has been studied and investigated as a dispersion compensator in optical communication system for different grating length and apodization functions at 10Gbps and 220km transmission fiber. All the simulation work has been done in "OptiSystem 7.0" simulation software. The simulated transmission system has been investigated on the different parameters that are Q-factor, BER, Eye height.Keywords

In the Access and Metro transport networks optical networks plays an important role. PON is an emerging technology which is having a higher bandwidth as well supports more users. In this Paper, two techniques of PON’s network that are TDM PON and WDM PON are presented and compared by the use 20 Users in optical Network Unit side. Performance is analyzed in terms of Quality factor and BER analyzer having 20 users of each 10Gbps data rate with the help of different receivers.
