The Huawei CGHF service board is a core service board designed for the MA5800 series OLT (Optical Line Terminal) equipment. It is primarily responsible for aggregating and processing optical fiber signals from a large number of users.
Its core feature is high-density "Combo PON" integration, which enables a single board and a single physical port to simultaneously support both traditional GPON and the higher-speed XG-PON access technologies.

The greatest value of CGHF lies in the smooth evolution of the network. Operators do not need to undertake large-scale overhauls of legacy fiber networks; simply replacing old line cards with CGHF units in the central office allows the same ports and fiber infrastructure to serve both new and existing subscribers simultaneously. This offers a cost-effective solution for FTTH network upgrades, earning it the reputation as the "key enabler for mixed-generation deployment."
