fibercore | permanent magnet gyroscope fiber

Product introduction

Fiber Core is the world's leading supplier of fiber optic gyroscope polarization maintaining fibers (FOGS). Through the use of "bow-tie" stress-applying components (SAPS), the stress can be effectively focused on the core, providing industry-leading levels of birefringence to maintain a high level of polarization extinction ratio (PER). By combining high birefringence with core-optimized gyro fiber coating encapsulation, the world's highest performance levels can be achieved.


The fiber range of PM gyroscopes offers the highest level of short beat length (SB) variants, high numerical aperture (NA) fibers (HI) to reduce macro and micro bending losses, small coil diameters and radiation tolerant (RT) variants for aerospace Task.


High polarization extinction from 55°C to +85°C


Maintains performance over a wide temperature range. Designed under test conditions to simulate conditions encountered in a typical fog circle. The extinction ratio of less than 30dB (H parameter is 1×10-5M-1) has been kept at -55℃, and the extinction ratio is over 28dB, which is -60℃.


 


Advantage:


1. "Bow tie" design, designed with superior birefringence


2. The world's best-selling gyro fiber


3. The best coating temperature performance


4. Radiation tolerant design for space applications


5. High NA design to reduce bending loss of small coil diameter
