The H902GPHF board is a 16-port GPON interface board for MA5800 series OLT. It works with the optical network unit (ONU) to provide GPON access services.
High density and low power consumption, supporting 2048 access users;
Chip-level type B protection (single-homing and dual-homing) and type C protection (single-homing and dual-homing) switching;
Real-time rogue ONT detection and isolation, ensuring stable service running;
4-level HQoS, improving user experience;
9216 jumbo frames, greatly improving transmission efficiency;
Variable-length of OMCI, improving upgrade efficiency and reducing break off time;
A maximum distance difference of 40 km between two ONUs under the same PON port, simplifying network planning;
VMOS, improving video troubleshooting efficiency.
