Abstract: The inventive concept relates to an optical line terminal registering optical network terminals having overlapping serial numbers. The optical line terminal may include a memory storing serial number information of optical network terminals of which a registration is completed in a storage region; and a control part that if a serial number by a serial number request is received from optical network terminals, the received serial number is compared with the serial number information of the memory and if they overlap each other, a previously set preliminary identifier is allocated to the optical network terminal having an overlapping serial number.
