摘要

PROBLEM TO BE SOLVED: To specify an abnormal ONU (Optical Line Terminal) without stopping communication an OLT (Optical Line Terminal) and an normal ONU.;SOLUTION: A value obtained by respectively subtracting light receiving levels in no light emitting mode when all ONUs do not emit the light of a signal from a light receiving level of a measured signal is calculated while the OLT can exclusively receive signals respectively transmitted from ONUs, the calculated value is respectively held in each ONU corresponding to timing, when it is determined that a signal transmitted at prescribed timing can not be exclusively received among signals respectively transmitted from the ONUs, a value obtained by subtracting a light receiving level of an ONU corresponding to a held prescribed timing and the light receiving level in the non light emitting mode from the light receiving level of the measured signal is calculated, the calculated value is respectively compared with a held value of each ONU, and an ONU corresponding to a value at which comparison results coincide is specified as an abnormal ONU.;COPYRIGHT: (C)2008,JPO&INPIT
