High performance fibers for precision wound FOG coils

Applications

• Fiber Optic Gyroscope (FOG)
• Current Sensors
• Fiber Sensors
• Couplers, sources, detectors, taps, isolators, modulators
• Delay lines

Features & Benefits

• PANDA designs for high birefringence, low cross talk, high consistency and mass production
• Radiation hardened and radiation resistant varieties available
• Extremely high birefringence ensures minimal gyrscope drift
• Small form factor for compact designs
• Low Tg coating for low cross talk variation over a wide temperature range (-55 to 105c)
• Long life expectancy at small coil diameters

Optical Benefits

• Bend insensitive and low loss - Lowest power consumption and longest coil lengths
• Low mode field perturbation along length – Minimizes crosstalk
• High birefringence – Minimizes crosstalk

Mechanical Benefits

• Very high fatigue failure resistance nd ~ 23 – Ensures long life expectancy at small coil diameters
• Long continuous lengths up to 5 km - high precision gyros up to strategic grade
• Standard formats as small as 40um clad/90μm coating – Allows max length on a small coil diameter
• Tight coating tolerances as low as 2um - repeatable fiber turns per coil layer
• Tight glass tolerances for ultra-low splice losses
