Abstract: PURPOSE: A method for allocating bandwidths for voice services in a GE-PON(Gigabit Ethernet-Passive Optical Network) is provided to offer a voice service within a preset transmission latency time and to efficiently use an allocated bandwidth. CONSTITUTION: An OLT(Optical Line Termination) transmits a transfer opportunity grant frame to each ONU(Optical Network Unit), synchronized with the OLT(S110). Receiving the transfer opportunity grant frame, each ONU transmits a response frame to the OLT.
