All over the world huge amounts of electronic data are transferred every day - faster and over longer distances. Data transfer is mainly via optical fibers. In order to transmit data without loss, optical fibers have to meet the highest quality requirements.
Online quality control of optical fibers in the drawing tower already starts below the furnace with diameter and position measurement of the uncoated fiber and the evaluation of the fiber spinning and tension by optical technology. After the forced cooling, the diameter of the optical fiber is measured once again. At this position also an airline detection and temperature measurement is carried out. After the optical fiber has received its coating and has gone through the UV drying process, a further measurement determines the diameter of the coated optical fiber and gives information on the coating concentricity. In a final step for quality control the surface of the optical fiber is inspected for any lumps and neckdowns.
With the FIBER Series 6000, SIKORA offers sophisticated optical technology for online measuring of optical fibers at different positions in the optical fiber drawing process. Information on optical fiber diameter, position, tension, airlines, temperature and concentricity is interfaced to the line control and supports manufactures to ensure highest product quality. The measuring values and information on the surface quality is visualized at a connected processor system and supports the manufacturer to take further actions to control and optimize the drawing process.
