Zusammenfassung:	Disclosed are an APR protection method and device, and a computer storage medium. A preamplifier PA of each of two optical amplifier units at two ends of a transmission line is connected to a booster amplifier BA of the other amplifier unit by an optical fiber. The method comprises: when a reception state of PA of at least one of two amplifier units is a loss of signal state and a switch chip of said amplifier unit detects a link interruption signal, activating an APR protection state of said amplifier unit which is to turn off BA output of said amplifier unit; when the switch chip of at least one of two amplifier units detects a link conduction signal, deactivating the APR protection state of the present amplifier unit to restore a state of BA of said amplifier unit to a state before the APR protection state is activated.
