  • Systems and methods for Ethernet-based management of optical networks using OMCI
    Patent number: 9270480
    Abstract: The present disclosure pertains to systems and methods for Ethernet-based management of optical networks using ONT management interface (OMCI). In one exemplary embodiment, an Ethernet-based protocol, such as Active Ethernet, is used to implement an ONT management interface (OMCI) between an optical line terminal (OLT) and a plurality of ONTs of a MON. Further, virtual local area networks (VLANs) are used to separate the traffic carried by the MON. Various techniques are described that permit ONT registration and creation of VLANs for the MON without requiring the use of gigabit PON (GPON) constructs, such as traffic containers (TCONTs) and dedicated GPON encapsulation method (GEM) ports.
