Rad-Hard PM Fiber performs for extended durations.
Press Release Summary:
February 5, 2014 - GyroSil® Rad-Hard PM Optical Fiber has 80 μm OD cladding and is bend-insensitive, enabling long lengths to be wound on small diameter coils. Manufactured without germanium, pure silica core fiber enables fiber optic gyroscopes to perform at higher radiation level for extended durations. Birefringent fiber has center wavelength of 1,550 nm and outer coating diameter of 145 μm. Suitable gyroscope applications include space, high altitude, and defense related navigation systems.

OFS Introduces GyroSil® Rad-Hard PM Fiber
Press release date: February 4, 2014
Brondby, Denmark — OFS announces an expansion of its line of GyroSil PM Sensing Fibers for gyroscopes. The new GyroSil Rad-Hard PM Optical Fiber is designed to perform in radiation environments. The new fiber has an 80 μm outside diameter cladding and is bend-insensitive, enabling long lengths to be wound on small diameter coils. GyroSiI Rad-Hard PM Optical Fiber is manufactured without the germanium typically used to dope optical fiber cores. Germanium is highly sensitive to radiation and causes a rise in attenuation which may compromise performance of the gyroscope. GyroSiI rad-hard PM optical fiber is a pure silica core fiber with radiation induced losses many times less than optical fibers doped with germanium. This highly birefringent fiber with a center wavelength of 1550 nm has excellent PM properties of low beat length and h-parameter. The outer coating diameter is only 145 μm.
“GyroSil Rad Hard PM opens up the opportunity for fiber optic gyroscopes to perform at a higher radiation level for a longer duration than conventional PM fibers”, says OFS VP Michael Fortin. “There are many gyroscope applications that will benefit from this fiber: space, high altitude, and defense related navigation systems to name a few,” concluded Fortin.
