Abstract
A method and a device is provided for managing an operating fault in a laser diode of an optical interface of user equipment of the ONU type. The user equipment is connected by an optical access network of the passive optical network PON type to line termination equipment of the OLT type. The user equipment is enabled to send an optical signal during a time slot allocated to the user equipment in accordance with a time-division multiple access principle. The laser diode is checked as to whether it is transmitting an optical signal outside the allocated time slot and, if so, a message to the line termination equipment is transferred if the fault is detected, deactivation of the laser diode is demanded, and one or more procedures for attempting to correct the fault are implemented.
