Abstract: A method for detecting a ferrule of optical fiber, a system for detecting a ferrule of optical fiber, a storage medium and an electronic device are disclosed. The method includes: controlling a laser generator to emit a laser beam with a preset power, and the laser beam is focused on an end face of the ferrule of optical fiber to be detected and passes into the ferrule of optical fiber to be detected; obtaining real-time brightness at one or more preset positions of the ferrule of optical fiber to be detected, the one or more preset positions at least include a position at an adhesive tail of the ferrule of optical fiber to be detected; receiving the real-time brightness, and determining whether the ferrule of optical fiber to be detected is qualified based on the real-time brightness.
