Huawei 030NHK GTMU gigabit trunk main unit board for OLT systems.

The Huawei 030NHK is a GTMU (Gigabit Trunk Main Unit) service board designed for use in Huawei optical line terminal (OLT) equipment. This board provides gigabit-level uplink trunk interfaces, enabling high-capacity data transmission between the OLT and the core network infrastructure.

The GTMU board is a critical component in Huawei’s GPON and xPON access network solutions, typically deployed in the MA5600T and MA5680T series OLT platforms. It handles aggregated traffic from subscriber-facing service boards and provides the necessary uplink connectivity to metro or core network switches and routers.

This is a legacy board associated with earlier generations of Huawei’s broadband access portfolio. While still in active use across many deployed networks, operators may seek replacement units for maintenance, capacity expansion, or sparing purposes as these platforms continue to serve existing subscriber bases.
