Measuring optical fibres more precisely

After seven years of intensive research, Sikora AG has further developed its Fiber Laser 6003 for the diameter measurement of bare fibres. Using the new measuring principle the diameter of optical fibres with a diameter from 50 micrometers can be measured with an accuracy of ± 0.05 micrometers. This is said to be ten times more precise than conventional measuring systems. Speeds of 2,500 measurements per second allow extremely precise single values and highest accuracy, even at high draw speeds. Statistical analyses are directly taken in the gauge head. By using an FFT-analysis the spin, vibration frequency and position of the fibre in the measuring field can accurately be defined. In addition, other randomly occurring non-conformities during production and/or during coating (caused by variations of line speed or vibrating fibres) are discovered at an early stage. The statistical distribution of short-term variations of the product parameters is graphically displayed during production on the processor system of the Ecocontrol-series in the form of a cloud diagram. The devices are factory-calibrated and maintain their accuracy for the life of the gauge. The gauge head technology ensures the quality of the fibre and thus assists in producing a product that provides reliable data transfer over long distances without data loss. The diameter sizing quality provided by the gauge guarantees a good connection of optical fibres. The measuring principle is based on Sikora’s patented laser-shadow projection principle. Sikora also offers the Fiber Lump 6003 T for lump detection in the drawing tower.
