Abstract
A method and device are provided for protecting a passive optical network including an optical-line terminal connected to a plurality of optical network terminals grouped set-wise. The method includes: obtaining a transmission schedule of the optical network terminals; comparing, by set, the schedule with the signals transmitted by the optical network terminals, and, if at least one optical network terminal of an assembly does not transmit in synchronization with the schedule, disconnecting the assembly.
