Huawei GPHF C++ | GPON Card | dedicated for MA5800 OLT

Huawei GPHF C

Huawei GPHF C is a 16-port Huawei NG OLT GPON interface card that provides access to GPON from the ONT. The GPHF, with 2.5 Gbps downlink and 1.25 Gbps uplink inserts, can access a maximum of 2048 subscriptions. The manual shutdown feature of idle PON ports prevents wasted power, and the use of 4-level HQoS (Hierarchical Quality of Service) technology and 9216 jumbo frames greatly improves the user experience.
