What is OLT (optical line termination)?

What is OLT

What is OLT : optical line terminal, which is a terminal device used to connect fiber trunks.

OLT functions

1. Broadcast Ethernet data to the ONU (Optical Network Unit) in broadcast mode;

2. Initiating and controlling the ranging process and recording the ranging information;

3. Allocate bandwidth for the ONU; that is, control the start time and send window size of the ONU to send data.

EPON OLT

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

The EPON passive optical network system is flexible in networking, and multiple terminals at the service access point within a radius of 20 km are connected to form an EPON system network. The system can support multiple business models, adapt to a variety of work environments, and provide users with FTTx series solutions.

In addition to providing the functions of service aggregation, the 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 not only monitors and manages devices and ports, but also enables service provisioning and user status monitoring, as well as bandwidth allocation for different users’ QoS/SLA requirements.
