The invention discloses a channel protection rearranging method for optical network equipment. The method comprises the following steps: when optical transfer network equipment detects a failure, the optical transfer network equipment rearranges services to an optical transfer network backup channel from an optical transfer network main channel, and an optical transfer network alarm indication signal is transmitted to passive optical network equipment; when the passive optical network equipment detects a failure, the passive optical network equipment detects whether the optical transfer network alarm indication signal is received or not, if so, the alarm generated by the passive optical network equipment is shielded so that the passive optical network equipment is not subject to channel protection rearrangement. The invention also discloses optical transfer network equipment and passive optical network equipment. In the invention the passive optical network equipment shields the alarm generated by the passive
