We propose a new optical access network architecture named “Mini-PON” that enables operators to deploy PON in various environments. Mini-PON uses pluggable module-type OLT and decomposed OLT software components in order to maximize flexibility and cost-efficiency. In the presentation, we explain the benefits of our proposed architecture, and how it actually works cooperating with OSS components in SEBA (e.g. ONOS and VOLTHA).
