Optical fiber with color ribbon identifier and coloring process method for optical fiber

Abstract

The invention relates to optical fiber surface coloring treatment, in particular to an optical fiber with a color ribbon identifier and a coloring process method for the optical fiber. According to the method, the optical fiber, of which the side face is identified through different color ribbons, can be drawn, so that people can identify the internal structures of special optical fibers perceptively or through some sets of simple equipment according to the color identifiers. According to the method, an optical fiber die and a drawing process are improved, so that one or more color ribbon identifiers in different colors are formed on the side face of the drawn optical fiber, and the internal structure of the optical fiber can be identified through the color ribbon; therefore, a fast axis and a slow axis of the optical fiber can be intuitively identified; a phenomenon of distortion of the optical fiber during encircling is avoided; and the stability of an optical fiber gyroscope is improved.

Description

technical field [0001] The invention relates to optical fiber surface coloring treatment, in particular to an optical fiber with a color band mark and a coloring process method thereof. The method can draw an optical fiber with color bands of different colors on the side to distinguish the internal structure of the optical fiber. Background technique [0002] In the past two decades, special optical fibers have developed very rapidly, and their application fields have become increasingly extensive. So far this technology has reached a higher level. In particular, the amount of polarization-maintaining fiber is increasing. Polarization-maintaining fiber is the main component of fiber optic gyro, and its manufacturing process is becoming more and more mature. However, due to the fast and slow axis of the polarization maintaining fiber, if there is a twisting phenomenon in the fiber winding process, the internal stress field of the fiber will change, and the polarization perf...

Problems solved by technology

However, due to the fast and slow axis of the polarization maintaining fiber, if there is a twisting phenomenon in the fiber winding process, the internal stress field of the fiber will change, and the polarization performance of the polarization maintaining fiber will change, thereby affecting the stability of the fiber optic gyroscope. , but the polarization-maintaining fibers sold in the market are not marked, so it is difficult to ensure that the fiber is not twisted during the looping process
