Simulation of a SAC-OCDMA 15 User System Using Hadamard Code

Today, optical systems are important element that suit the consumer to expand important services in this civilized age. These networks are developed on the basis of the optical fiber bandwidth frequency using optical spread spectrum system and through Optical Code Division Multiple Access technologies OCDMA and a good solution for high bandwidth networks. In this message, we propose a system to increase the number of users. To meet future demands these networks should be developed where OCDMA is designed and simulated for the purpose of expanding the communication network by increasing the data transfer rate. To add the numeral of users in the network should check a encoder/decoder OCDMA system. In addition, Optical Fiber system (OFS) is utilized with some of incoherent (SAC- OCDMA) code using hadamard code to reduce the Multi Access interference (MAI) effect in OFS. MAI is one of the most important factors affecting system performance. In this simulator the transmitter adopts Mach- Zehnder Modulators (MZM) and light source for multi-source electrical data transmission where it provides low cost, high transmission power and easy system implementation. Using the program optisystem Ver.15.
