Powerful integrated GPON access capability
1.MA5608T FTTH OLT Supports high bandwidth. The downstream rate is up to 2.488 Gbit/s and the upstream rate is up to 1.244 Gbit/s.
3.MA5608T FTTH OLT Supports long distance. The maximum physical transmission distance of the ONT is 60 km. The physical distance between the farthest ONT and the nearest ONT can be up to 20 km.
4.MA5608T FTTH OLT Supports high split ratio. The 16-port GPON board supports 1:128 split ratio, which increases the access capacity and saves the optical fiber resources.
5.MA5608T FTTH OLT Support high density. The MA5600T series provides the 8-port and 16-port GPON board to increase the system capacity.
Powerful QoS capability
1.MA5608T access mini olt Supports priority control (based on the port, MAC address, IP address, TCP port ID, or UDP port ID), priority mapping and modification based on the ToS field and 802.1p, and DSCP differentiated services.
