We demonstrate an optical fiber current sensor based on the Faraday effect in gallium- substituted yttrium iron garnet that has a measured sensitivity of approximately 3.0°/A, a noise-equivalent current of about 500 nA/√Hz, and a 3 dB bandwidth of approximately 10 MHz. The sensitivity-bandwidth product is about a factor of 40 greater than an all-fiber current sensor with the same diameter.
