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.
