The working principles of the reflection of an All fiber optical current transformer (FOCT ) were described,the characteristics of transformer out-put signal demodulation system were analyzed,and on this basis,an all fiber optical current transformer de-modulation system were designed. Furthermore an FPGA+MCU implementing method was provided and a demodulation system for the all fiber optical current transformer was developed.Test results showed that the demodulation system could parse the all fiber op-tical current transformer AC and DC signal demodula-tion.Therefore,the verification system can meet the requirements for application in all fiber optical cur-rent transformers .
