<p>A passive optical network system, a optical line terminal, a method for generating and authtenticating authentication information are provided. The method for authentifying determines the multiple cyclic ranging results and acquires the multiple cylic ranging between a subscriber end device and an optical line terminal; generating the ranging authentication determining information between the subscriber end device and the optical line terminal according to the cyclic multiple ranging determining results; then obtaining the ranging authentication information for prestored information between the subscriber end device and the optical line terminal; finally, comparing the ranging authentication determining information and the ranging authentication information so as to confirm the authentication results. According to one embodiment of the present invention, enlarging the difference corresponding to the value obtained by multiple ranging, when setting lines in the optical distribution network, avoids the need for ensuring the minimum gap between an optical line terminal offset length, thus simplifying the setting line process.</p> |
