The measurement of Faraday rotation can be made insensitive to linear birefringence by time multiplexing of different states of polarization at the input of the fiber. This offers a new possibility of overcoming the linear birefringence effect in fiber current sensors. Experimental results and the measurement accuracy versus the quality of the optical components used are presented.
