Ultra-Low Profile, High Birefringence Fibers for Fiber Optic Gyroscopes

To enable rapid development of new Fiber Optic Gyroscopes (FOGs), Fibercore have developed a new 60µm, ultra-low profile, high birefringence Polarization Maintaining (PM) fiber for FOGs. By optimizing the design parameters based on Fibercore’s significant experience in supplying the FOG industry with optical fibers, this fiber is shown to give enhanced mechanical reliability in a small coil diameters, improved bend loss, smaller physical size and equivalent Polarization Extinction Ratio (PER) performance over temperature as a standard 80µm FOG fiber. This allows FOG system designers to replace their existing 80µm fiber with the new 60µm fiber to gain extra sensitivity or to develop new micro-gyros.
