A novel ring architecture of multiple optical private networks over EPON using OCDMA technique

We propose a novel ring architecture to install multiple optical private networks (PNs) on EPON infrastructure. The PNs are demonstrated to be independent of OLT which does not add any supplement traffic management into OLT. We experimentally demonstrate two active PNs communications using OCDMA technique in which ONUs within PN are interconnected and sharing the same codeword.
