Résumé
In an asynchronous environment, optical code division multiple access (OCDMA) is an advanced technique. However, this technique shows limitations in terms of the low spectral density and inefficient bandwidth utilization when implemented with one-dimensional (1D) codes. Thus, this study presented a novel two dimensional (2D) spectral/spatial multi-wavelength code to overcome these limitations. The proposed code is formulated using a 1D balanced incomplete block design (BIBD) technique. It is designed and implemented for spectral amplitude coding (SAC) based OCDMA networks and constructed using a 1D BIBD code matrix. Optisystem software-based simulation results indicate that the proposed code provided improvement in the number of simultaneous users, code construction, cross-correlation, and minimize the noises. Due to its practical code design approach, the proposed code family yields large cardinality with optimal code length. Moreover, system performance illustrates that the system with the proposed code maintains required optical transmission property by supporting six clients for source power -10 dBm with the data transmission rate of 1 Gbps.
