The SAC OCDMA PON With Super Perfect Difference Code

Free registration required

Executive Summary

In this paper, the Super Perfect Difference (SPD) code family is presented and used in the compact Spectral Amplitude Code (SAC) Optical Code-Division Multiple-Access (OCDMA) Passive Optical Networks (PONs). Based on the excellent properties of the SPD code, such as low In-Phase Cross Correlation (IPCC) value, cyclic shift, and excellent orthogonality, the authors design the SAC OCDMA PON which consists of a compact Optical Line Terminal (OLT) and many simple Optical Network Units (ONUs). Accordingly, the proposed PON not only can accommodate a large number of simultaneous users but also has compact configuration and good Bit Error Rate (BER) performance with moderate security.
