EPON passive optical network system function

1. Broadcast Ethernet data to ONU (optical network unit);

2. Initiate and control the ranging process, and record the ranging information;

3. Allocate the bandwidth for the ONU; namely, control the starting time of the ONU to transmit data and the size of the transmission window.

The central office equipment (OLT) in the EPON passive optical network system is a multi-service providing platform that supports IP services and traditional TDM services at the same time. It is placed at the edge of the metropolitan area network or at the exit of the community access network to converge the access services and deliver them to the IP network respectively.

The EPON passive optical network system has flexible networking, and multiple terminals located at the service access point within a radius of 20 kilometers are connected to form an EPON system network. The system can support a variety of business models, adapt to a variety of working environments, and provide users with FTTx series solutions. In addition to providing the function of service aggregation, OLT is also a centralized network management platform. Device-based network element management and service-based security management and configuration management can be implemented on the OLT. It can not only monitor and manage equipment and connection ports, but also perform service provisioning and user status monitoring, and can also allocate bandwidth according to the QoS/SLA requirements of different users.
