ABSTRACT:
A GEM OAM frame transmission method used in a Gigabit-capable passive optical network is provided. The method defines an OAM frame structure in a GEM mode of the Gigabit-capable passive optical network and enables an OAM to be achieved even when the GEM mode is operated. The method comprises the steps of: constructing a GEM OAM frame including a GEM header field and a GEM payload field, the GEM header field containing OAM representation information indicating that the GEM OAM frame contains the OAM information, the GEM payload field containing the OAM information; and transmitting the constructed GEM OAM frame in order to enable the ONU/ONT to perform an operation according to the OAM information.
