The optical cable is a main transmission tool of various information networks in the information society at present, the optical fiber is used as a core unit of the optical cable, and in order to distinguish the optical fiber in the optical cable or the sleeve, the color identification is generally adopted in the industry to distinguish different optical fibers. The optical fibers are colored mainly by two modes, namely coloring and coloring, and the corresponding optical fibers are colored optical fibers and colored optical fibers respectively.
Coloring is a way for most optical fiber and cable manufacturers to color optical fibers at present, as shown in fig. 1, a colored optical fiber mainly comprises 4 layers, wherein the center of the colored optical fiber comprises a cladding, a first inner coating is arranged outside the cladding, a second outer coating is arranged outside the first inner coating, and a thinner colored ink layer is arranged outside the second outer coating. The colored optical fiber is usually manufactured by spraying a thin layer of ink on the second outer coating of the original optical fiber which is drawn and passes through screening tension, and then coloring the optical fiber after UV curing, while the outer coating of the colored optical fiber in the drawing process contains organic dye, and the manufactured optical fiber contains color, as shown in figure 2, so that the colored optical fiber can directly enter the plastic sheathing process for production without a coloring process. Because the colored optical fiber is directly obtained by drawing production, the outer diameter of the colored optical fiber is better controlled, and the outer diameter value, the concentricity and the out-of-roundness are incomparable with those of the colored optical fiber.
Colored fibers, while good, have limitations. Most of optical fiber manufacturers are carrying out intelligent and simplified transformation on production lines at present, and corresponding coating supply modes are also transformed into all modes of concentrated feeding of wire drawing lines by using small barrels of coatings on the production lines. Concentrated feeding can greatly reduce personnel operation, and reduce the phenomena of coating replacement error caused by human error, coating failure caused by improper operation and the like to cause wire drawing and fiber breaking. However, the popularization of centralized feeding causes inevitable problems to the production of colored optical fibers: all drawn wires can produce colored optical fibers of only one color.
