BRONDBY, Denmark, Feb. 13, 2014 — OFS has added the GyroSil Rad-Hard PM optical fiber to its line of sensing fibers for gyroscopes.
Designed to perform in radiation environments, it has an 80-µm outside diameter cladding and is bend-insensitive, enabling long lengths to be wound on small-diameter coils.
Its pure silica core fiber offers radiation-induced losses many times less than optical fibers doped with germanium, an element highly sensitive to radiation. The birefringent fiber has a center wavelength of 1550 nm and polarization maintaining (PM) properties of low beat length and h-parameter. The outer coating diameter is 145 µm.
Gyroscope applications that could benefit from the fiber include space, high- altitude and defense-related navigation systems.
