This paper is forcusing on the optimization simulation analysis of the network structure optical division multiple access (OCDMA) technique is investigated using the 2-D Hybrid OCDMA code. The performance was analyzed using Optisys software. During the simulation process, various parameters, variables such as distance of the fiber, bit rate and number of users are analyzed. The results indicate that with bit rate of 155 Mbps, 4 numbers of user the 2-D Hybrid OCDMA code can achieve maximum transmission of 80 km with bit error rate (BER) 4.99x10^-9. At 622 Mbps and 1.1 Gbps both can achieve maximum transmission of 60 km with BER 8.31x10^-9 and 45 km with BER 6.44x10^-9 respectively. For 9 users, the 2-D Hybrid OCDMA code of bit rate 155 Mbps, can achieve maximum transmission of 65 km with BER 8.31x10^-9. At 622 Mbps and 1.1 Gbps respectively, it can achieve maximum transmission at 40 km and 35 km with BER 1.51x10^-9 and 5.49x10^-9.
