The invention discloses an optical current transformer having an anti-vibration function and an anti-vibration interference method realized by adopting the current transformer, and belongs to the electric power system current measuring field. A problem that the accuracy of the output results of the conventional optical current transformer is affected by external vibration interferences is solved. The optical current transformer comprises a primary processing part, a transmission optical fiber part, and a secondary processing part. Bidirectional simulation optical information exchange between the primary processing part and the secondary processing part is carried out by the transmission optical fiber part. The primary processing part is used to sense current signals, and is used to load the sensed current signals on carrier light generated by the secondary processing part, and the secondary processing part is used for the anti-vibration processing of the carrier light of the loaded and sensed current, and therefore processed current information is acquired. The optical current transformer and the anti-vibration interference method are mainly used for the electric power system current measuring field having high vibration interference intensity.
