Yes sorry, in GPON you have the unit at the telco side, often called OLT (optical line termination/terminal or similar, which feeds the whole segment of up to ~128 remote terminals and receives data from all) the passive splitter (if any) and the remote customer units that are called either ONU or ONT, but that are just two names for the same unit (not sure who uses which nomenclature, the local incumbent seems to prefer ONU, but their marketing name is Glasfasermodem, which just translates to fiber-modem). Nomenclature seems ot be consistent for the whole PON family, so in XG-PON or XGS-PON the unit apparently still are called OLT and ONU/ONT. And given that PON requires some smarts and configurability of the ONUs these tend to be small computers in their own right with their own little (or not so little) OSes.
