The continuous quality control in the optical fiber manufacturing requires a reliable and efficient measurement technology. SIKORA sets standards in this area. This high quality of optical fiber is demanded, to reliably transport large amounts of data over long distances, without any loss of data.
The FIBER LASER 6003 is an innovative device for diameter measurement of optical fibers directly in the drawing tower. The unique measuring principle assures an accuracy of 0.05 µm at a repeatability of 0.02 µm. 2,500 measurements per second with high single value precision and a short exposure time of 1.2 µs always guarantees the highest accuracy. The measuring principle is based on diffraction analysis. It allows for a non-contact, optical measurement of diameters without moving parts. Calibration is not necessary.

This multi-purpose device is used for the measurement of the diameter and the detection of smallest airlines (air pockets in the fiber) from 0.5 µm diameter. The FIBER LASER 6003 AIRLINE, typically installed prior to the coating, is factory-calibrated and keeps it absolute accuracy for the entire life-cycle.

In order to precisely evaluate the concentricity of the coating, the FIBER LASER 6003 can optionally be equipped with an additional function. This FIBER LASER 6003 CCE (Coating Concentricity Evaluation) is installed after the coating cup and provides information on the coating concentricity as well as diameter values.
As the FIBER LASER 6003 CCE replaces the FIBER LASER 6003 within the drawing tower for the diameter measurement of the coated fiber, an additional diameter gauge head is not necessary.

The FIBER TEMP 6003 is a standalone gauge for the measurement of the fiber temperature during the drawing process.
The gauge head can be installed at the cold (measuring range 40° to 120 °C) or at the hot end (measuring range 500° to 1,500 °C) of the fiber line. To ensure the right temperature at both positions, two FIBER TEMP 6003 devices should be installed, for the highest stability of the process. The measurement at the hot end provides an important process parameter for the control of the furnace. With the FIBER TEMP 6003 at the cold end, the temperature of the fiber can be optimally adjusted and kept stable before it enters the coating. Furthermore, the required helium cooling can be reduced to a minimum, resulting in a cost reduction.
In combination with the FIBER ECONCONTROL, the temperature measurement is displayed and also available in the trend diagram.

Lump detectors are essential for continuous quality control in drawing towers. The 3-axis FIBER LUMP 6003 reliably detects lumps and neckdowns with a height/depth of 10 µm and a length of 500 µm.
For even higher quality requirements, SIKORA offers the FIBER LUMP 6003 MICRO. The device detects non-conformities on the optical fiber surface from a length of 50 µm to 100 %. This performance is achieved by the integration of 6 measuring axes. Both gauge heads detect faults from a height of 5 µm.
Absolute perfection for the detection of lumps/neckdowns guarantees the SIKORA double sensor technology. All faults are documented regarding height, length, number and position. The lump detectors are available for product diameters from 100 to 500 µm and can be easily integrated into a new or already existing drawing tower. The lump detectors can either be connected to the SIKORA processor system FIBER ECOCONTROL or to a line computer.

The FIBER TENSION 6003 serves as a supplementary measuring device for an even faster, more robust and improved tension measurement to validate and control this important measuring and control parameter. This is made possible by the remarkable measuring rate of up to 50 kHz and the use of a measuring principle which takes the refractive properties of glass into account.
The use of the stand alone device is particularly attractive for manufacturers of high-end solutions where the process is controlled by the tension. The FIBER TENSION 6003 is predestined for optical fibers being processed into premium optical fiber cables for which particularly high requirements and standards exist.
The integrated measuring principle is based on the principle of birefringence. The FIBER TENSION 6003 can be used for both hot and cold measurement of the bare fiber, independent of production influences such as the position of the fiber in the measuring field, the production speed and the vibration or oscillation of the fiber. Installed before or after cooling, the system generates reliable and stable measuring values and thus enables direct control of the tension.
