Spun optic fiber is mainly used in key sensitive devices such as optic fiber current transformer, which has the ability of maintaining circular polarization and resisting environmental interference. The high birefringence fiber preform is used to spin at high speed in the process of wire drawing. The two intrinsic modes of the spun optic fiber manufactured by this special process are elliptically polarized, and its inherent birefringence can effectively resist the stress caused by external conditions (such as temperature, bending, vibration, etc.), in order to effectively maintain the characteristics of circularly polarized light. Spun optic fiber can not only maintain circularly polarized light, but also has a very outstanding ability to resist environmental interference, and can ensure extremely high working accuracy under the conditions of temperature fluctuation and vibration. Good geometric and optical properties.
*Good geometric and optical properties;
*With minimal phase difference, circular polarization transmission can be maintained over long distances
*Spun optical fiber is Insensitive to temperature and stress;
