The U reference point represents the customer-facing interface of the ONU/ONT. It is possible that the U reference point can be within the ONU/ONT device when ONT and RG devices are combined into a single device.

The R/S reference point represents the OLT facing ONU interface.

The S/R reference point represents the Optical Distribution Network (ODN) connecting GPON interface on the OLT. The S/R and R/S interfaces contain all the protocol elements necessary to allow communication between OLT and one or more ONUs over ODN.

The V reference point represents the network-facing interface of the OLT.
