Background
With the continuous development of Optical networks and the implementation of broadband strategy in various countries, Fiber-to-the-x (Fiber-to-the x, x is H for home, pforpromies C for curb and N for node or neighbor borwood) in which FTTH Fiber to home, FTTP Fiber to home, FTTC Fiber to roadside/cell, and FTTN Fiber to node have been spread comprehensively, and Optical Network Units (ONU) as end products thereof have also been widely used. In order to facilitate the remote maintenance of various types of information of the ONU by the central office, the ONU needs to report various types of alarm messages to an Optical Line Terminal (OLT for short) of the central office device in real time in different scenarios, and the power failure alarm belongs to one of the types of messages.
The principle of the function is that when the ONU detects that the voltage is lower than a certain specified threshold range in the power-down process, the ONU needs to send a power-down alarm to the OLT in real time within a power-down keeping time period to inform the OLT that the OLT is in a power-down closing state.
The function mainly aims to indicate the current power-off state of the ONU to the OLT, and distinguish the current power-off state from states such as fiber breakage and the like, so that convenience is brought to maintenance and state check on engineering. The function is widely used in actual use, but the function only considers theoretical conditions on the standard and does not consider some conditions in the actual use process, so that the following problems are caused:
1. due to the fact that voltage and other problems are actually used, the actual voltage of the ONU triggers the power failure alarm in a short time, and then the actual voltage is recovered, so that the ONU reports the power failure alarm, but the actual state of the ONU is online;
2. due to the fact that voltage and other problems are actually used, the actual voltage of the ONU triggers power failure alarm in a short time, and after the actual voltage is recovered later, certain parts of the ONU are abnormal in work and are in abnormal working states;
3. due to the fact that voltage and other problems are actually used, the actual voltage of the ONU triggers the power failure alarm within a period of time, so that the ONU continuously sends the power failure alarm within the period of time, and a large amount of impact is generated on local end equipment (OLT).
Aiming at the problem that in the related art, when the ONU reports the power failure alarm information, only theoretical conditions are considered, and some conditions in the actual use process are not considered, so that the power failure alarm information is reported by mistake, an effective solution is not provided at present.
