Explanation
MA5600T is a Huawei OLT (Optical Line Terminal), which is the carrier-side aggregation equipment installed in central offices or street cabinets - not an ONU. The other three options are all Huawei ONU/ONT devices designed for the customer premises side of a passive optical network: the MA5612 is an outdoor ONU/MDU, the MA5652G is an enterprise-grade ONU, and the HG8247 is a home gateway ONT commonly deployed in residential GPON installations.
Memory tip: ONU devices sit at the "user" end of the network. The MA5600T's "T" stands for Terminal - but it is the operator's terminal, not the user's, making it an OLT. If you remember that the MA5600T is the large chassis OLT platform (the one that aggregates traffic from many ONUs), you will not confuse it with the ONU series on exam day.
