Abstract :
The benefits of employing 2-Dimensional (2D) Wave-length/Time (W/T) Hybrid code to mitigate the optical noise in spectral amplitude coding OCDMA networks system is in-vestigated. This analysis allows us to identify the influences of optical noise such as PIIN noise, shot noise and thermal noise in the system performance by using 2D Hybrid FCC-MDW code. The mathematical calculation reveals this new code effectively mitigates the Phase Induced Intensity Noise (PIIN) and eliminates Multiple Access Interference (MAI). As a result, the performance of the system can be improved as well as support much more simultaneous users compared to 2D Perfect Difference (PD) and 2D M-matrices codes.
