Abstract: | This work is a novel attempt to provide local communications for multiple optical private networks (PNs) within ring-based
passive optical network (PON). In order to improve network throughput performance, PNs traffic is decentralized from PON traffic
let no extra traffic management into optical line terminal (OLT). To achieve multiple secure optical private networking over
ring-based PON layout, optical code division multiple access (OCDMA) technique is applied. This technique leads to interconnect
optical network units (ONUs) in the same PN sharing the same codeword while other PNs benefiting from different codewords.
This scheme can be used in access networks to establish discrete communications between different sites in an enterprise or
a university campus or even a residential accommodation. The proposed network architecture is then set up and its bit error
rate performance is experimentally demonstrated. Finally, the network scalability and throughput performance of the proposed
scheme are analyzed. |
