In this paper, a protection architecture that can be applied to NG-PON2 system, or TWDM-PON, is proposed. NG-PON2 system provides bandwidth as much as 80 Gbps in downstream, and the system failure may cause a serious problem. Therefore, its protectio

In this paper, we propose a novel passive optical network (PON) architecture that has multiple optical line terminals (OLTs). Unlike existing PONs where all ONUs are connected to a single OLT, the proposed multi-OLT PON allows subscribers to choose t
