The Influence of Ink on Attenuation of UV-curable Colored Optical Fibe

The influence of UV-curable ink on attenuation of colored optical fiber has been examined. The components in the ink affected the attenuation of colored optical fiber in the order of resin>active diluent>dye. The attenuation increment of colored optical fiber was in the following sequence:bisphenol epoxy diacrylate>aromatic urethane diacrylate>aliphatic urethane diacrylate>polyester diacrylate with the other components in ink kept constant. The attenuation increment of colored optical fiber decreases with the increase of line-velocity of coloration of optical fiber. All these effects were found related with the modulus of cured resin system of ink. The greater the modules, shows the greater attenuation increment of colored optical fiber. The cured ink with greater modules probably provides for the colored fiber a greater stress, increase radiation loss, therefore, enhanced attenuation increment.
