Measuring optical fibres more precisely

randomly occurring non-conformities dur- ing 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. are factory-calibrated and maintain their accuracy The devices

Windak has announced that the first of its new generation of automatic coilers, the FC5, has been successfully installed in Finland. According to Urban Bollo, managing director of Windak Sweden, the FC5 automatic flex coiler is the first machine Windak has introduced as part of a new generation of affordable automated packaging solutions. “We understand that the market today demands cost-effective solutions that have a short pay-back time with maximum flexibility and output.” FC5 is compact and accommodates a wide range of cable diameters and coil sizes. It features fully automatic coiling with or without a strapper or binder. Without a strapper or binder the coil is stretch-wrapped before it exits the coiling head. 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 be accurately defined. In addition, other 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 of 50 micrometers or more can be measured with an accuracy of ±0.05 micrometers. This is said to be ten times more precise than conventional measuring systems.

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.
