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.

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.
