In the downstream direction, the bandwidth is shared by different users in the encrypted broadcast mode. In the upstream direction, time division multiplex(TDM) is used to share the bandwidth.
The MA5680T series support dynamic bandwidth allocation (DBA) with the granularity of 64 kbit/s. Therefore, the bandwidth of ONT terminal users can be dynamically allocated based on the user requirements.
The EPON system uses the passive optical transmission technology, and the optical splitter uses the P2MP mode and supports a split ratio of 1:64.
The supported transmission distance is up to 20 km.
The ranging technologycan be scheduled ranging, automatic ranging, or initial ranging.
