Zusammenfassung:	The utility model relates to a rapid-responding power-off sensing module which comprises a first module and a second module, wherein the first module comprises a relay control portion connected to the power supply inlet wire. The power supply inlet wire is connected with the AC input end of an AC/DC converter, and a first capacitor (C1) is connected between the two DC output ends of the AC/DC converter. The DC output ends of the AC/DC converter access to the input ends of a DC/DC converter, a second capacitor (C2) is connected between the two DC output ends of the DC/DC converter, and the output ends of the DC/DC converter is connected with an optical switch via the controlled portion of the relay. The rapid-responding power-off sensing module rapidly responds to the failure or power-off of one transmission device in an optical communication network.
