OLT function

 

In EPON passive optical network system, OLT is a multi-service platform, which supports both IP services and traditional TDM services. Place it at the edge of MAN or the outlet of community access network, converge access service and pass it to IP network separately.

 

EPON passive optical network system is flexible in networking, with multiple terminals in the service access point within 20 kilometers of downlink radius, constituting the 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 of solutions.

 

In addition to providing business convergence functions, OLT is also a centralized network management platform. Device-based network element management and service-based security management and configuration management can be realized on OLT. It can not only monitor and manage devices and ports, but also carry out business start-up and user status monitoring. It can also allocate bandwidth according to different users'QoS/SLA requirements.

 

The OLT routing function test method can be fully automated with CDRouter.
