The H902CGHF board is an 16-port XG-PON and GPON Combo OLT interface board for MA5800 series OLT. It works together with the optical network unit (ONU) to provide XG-PON and 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;
ensuring 4-level HQoS, improving user experience;
9216 jumbo frames,greatly improving transmission efficiency;
Smart processing of XG-PON and GPON services,meeting hybrid service requirements and reducing board and spare part types;
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 (board capability), simplifying network planning;
VMOS, improving video troubleshooting efficiency.
