1550nm polarization-maintaining gyroscope fiber PM1550G-80/125-5
The Coherent/Nufern Panda-type polarization-maintaining gyro fiber features extremely high birefringence and extremely strict fiber dimensional tolerance control, suitable for fiber coils used in high-precision, high-performance fiber optic gyroscopes. The small coating design (125um) allows users to make smaller fiber optic gyroscopes and sensors. The high consistency of PM fibers in this series and the extremely strict end-to-end optical performance control provide particular advantages in applications where signal distortion must not occur with a small cladding; in addition, its high radiation resistance gives the PM fibers of this series a longer service life in low earth orbit, near space and deep space, as well as in environments exposed to strong man-made radiation.
