The purpose of the coloring process line is to give the optical fibers a distinctive, smooth, stable and reliable color for easy identification of optical fibers in the optical cable production process and in the use of the optical cable. The main raw materials used in the coloring process are optical fibers and colored inks. The color of the colored inks is divided into 12 kinds according to the industry standard. The chromatographic arrangement according to the radio, television and industry standards and the Ministry of Information Industry standards is not the same. (White), red, yellow, green, gray, black, blue, orange, brown, purple, pink and green. The industry standards of the Ministry of Information Industry are listed as follows: blue, orange, , Red, black, yellow, purple, pink, green. In the case of recognition does not affect the use of the color instead of white. The company is now using the chromatographic arrangement of the Ministry of Information Industry standards, the user requirements can also be radio and television industry-standard chromatography. When the user requires more than 12 cores per tube, different colors can be used to differentiate the fibers with different colors according to the needs.
Optical fiber coloring should meet the following requirements:
1, colored fiber color does not migrate, do not fade (with butanone or alcohol wipe also so).
2, fiber optic cable tidy, smooth, not mess line, not pressure line.
3, fiber attenuation index to meet the requirements, OTDR test curve without steps and so on.
The equipment used in the optical fiber coloring process is the optical fiber coloring machine. The optical fiber coloring machine consists of the optical fiber pay-off part, the coloring mold and the ink supply system, the UV curing furnace, the traction, the optical fiber take-up and the electrical control part. The main principle of UV curable ink coated by the colored mold on the optical fiber surface, after curing UV curing oven fixed to the optical fiber surface, the formation of easy-color separation of the optical fiber. The ink used is UV-curable inks.
