Abstract

The analysis realization performance of 2-dimensional (2-D) code OCDMA system with the AND Detection technique was investigated. Two codes of 2-D has been employed in this project for OCDMA system; the 2-D M-Matrices code and 2-D Hybrid code. The performance was analyzing using Opti-Sys software. During simulation process, various parameters varied such as distance of the fiber, bit rate, and number of users. The result indicates that 2-D Hybrid code system modulated at 155 mbps has produced lower bit error rate (BER) of 8.31×10^-9 at 65 km for 9 users in comparison to 2-D M-Matrices code system which can only achieve the maximum transmission distance at 25 km with BER of 1.16×10^-9. It shows that the 2-D Hybrid code has better phase induced intensity noise suppression in comparison to the 2-D M-Matrices code.
