  • Polarization Maintaining Fiber(for Fiber-optic Gyroscope)

    TFO's 1550nm PANDA-style PM Gyroscope fibers are
    manufactured by the vapor-phase axial deposition(VAD)
    process to exhibit the highest quality with high
    birefringence, precise dimensional specifications
    and high-performance gyro-coils.
    TFO's PANDA fibers have stable performance with
    temperatures ranging from -40°C ~ +85°C. 80µm
    of fiber diameter saves space and enhances lifetime.
