Abstract
Embodiments of the present disclosure relate to an optical line terminal (OLT), an optical network unit (ONU), communication methods, communication apparatuses, and computer-readable media. In an exemplary method, the OLT determines an optical communication capability of the OLT which includes at least one of the following: at least two upstream wavelength options supported by the OLT, a passive optical network (PON) mode associated with the OLT, and an upstream modulation format used by the OLT. In the method, the OLT further transmits, to the ONU, at least one indicator indicating the optical communication capability. In this way, the OLT can negotiate the optical communication capability with the ONU, thus avoiding data transmission failures or performance degradation caused by device incompatibility.
