Performance of all fiber optical current transducer in optical transmission based on optisystem

The all fiber optical current transducer (AFOCT) modulation technique was designed in this paper, and the capabilities of fiber optic sensor was simulated by the software of Optisystem. The direct detection AFOCT transmission over the source function, the optical system, processing of optical signal was addressed. And the performance of different signal from of the direct detection structure was simulated. The pulse signals were processed by using the Optisystem, and the feasibility of the proposal has been validated.
