Passive Optical Networks (PON) have garnered interest in recent years from network providers and researchers alike owing to their tremendous economic advantages for application in last mile services and optical sensing. Optical code division multiple access (OCDMA) is a multiplexing technique that has a number of inherent advantages that make it suitable for use in passive optical networks. Such as large capacity, high security and excellent anti-interference ability, which make OCDMA a forefront topic of research in all-optic access networks. To satisfy future bandwidth demands, existing Fiber To The Home (FTTH) access networks must be upgraded to guarantee at least a 100 Mb/s dedicated connection per subscriber. Fiber To The Home is one of the applications of the passive optical network. In this thesis, we introduce passive optical network technology in detail, especially Fiber To The Home depended on optical code division multiple access structure. Then we use (Optisystem ), software program to design and analyze the networks. Firstly, we design and analyze three users fiber-to-the-home network at 200Mbps for each user. Also we study the effect of increasing distance of fiber link and optimize data rate. Secondly, we design and analyze seven users system network at 200Mbps for each user. Then we discuss the effect of increasing length of fiber cable, increasing number of users and input power. Thirdly, compares my design result with related work. Finally, several measurements are found;, Bit Error Rate (BER), Maximum Quality Factor (Max Q). We found the BER increased exponentially with distance , bit rate, and number of users . Also we found the optimal minimum bit rate at 125 Mbps and maximum bit rate at 300 Mbps can be transmit.
