<p>An optical fiber current sensor comprises: TOSA (Transmitter Optical Subassembly) packaged with a linear polarizer which makes light incident to sensor coils made of optical fiber through linear polarization of light from a light source; ROSA (Receiver Optical Subassembly) packaged with a polarizing light splitter which splits reflected lights from sensor coils depending on polarization and a first and a second photo detector which respectively detect lights split based on polarization.</p> |
