FIBER Series 6000

Highest precision in the draw tower

Innovative measuring technology for optical fiber production

Following the market launch of the LASER Series 6000 SIKORA developed technically sophisticated equipment with the devices of the FIBER Series 6000, for a comprehensive measurement and analysis of optical fiber production in the draw tower. The new series combines most precise measuring methods with innovative functions to a system solution in a class of its own.

FIBER LASER 6003 for diameter measurement of optical fibers

The FIBER LASER 6003 is an innovative device for diameter measurement of bare as well as coated optical fibers 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 highest accuracy.

 

The measuring principle is based on diffraction analysis. With the measurement according to that method SIKORA became the worldwide technology leader. It allows for a non-contact, optical measurement of diameters without moving parts and no need for calibration.

 

Typically a first gauge head is installed after the preform to measure the diameter and position of the bare fiber. On the basis of this information this gauge head also calculates the tension by means of a Fast Fourier Transformation (FFT). The single values of the fiber position and the vibration frequency are graphically visualized by the processor system FIBER ECOCONTROL in the form of a scatter plot and are available via ETHERNET.

 

A second gauge head before the coating measures the cold diameter of the fiber and provides spinning information via FFT of the ovality. This device is typically used for diameter control. But also the first gauge head after the preform can realize the control. This is decided by the manufacturer of optical fibers.

 

Additional FIBER LASER 6003 devices measure the diameter after the primary and secondary coating. These gauge heads also provide information on the concentricity.

 

FIBER LASER 6003 AIRLINE for diameter measurement with airline detection

Besides the FIBER LASER 6003 installed before the coating, SIKORA offers the FIBER LASER 6003 AIRLINE, a device which detects smallest airlines from 0.5 µm (diameter). The FIBER AIRLINE may also be installed after the preform.

 

FIBER LASER 6003 and FIBER LASER 6003 AIRLINE are factory-calibrated and keep their absolute accuracy for the entire life-cycle. These gauge heads can be connected to the SIKORA display and control system FIBER ECOCONTROL as well as to a line computer.

 

FIBER LUMP 6003 for lump detection on the surface of optical fibers

Lump detectors are essential for continuous quality control in drawing towers. The 3-axis FIBER LUMP 6003 reliably detects the smallest lumps and neckdowns down to a minimum size of 5 µm at a length of 50 µm.

 

The FIBER LUMP 6003 is used for product diameters from 0.1 to 1.5 mm. The device can easily be integrated into a new or already existing drawing tower. The lump detector can be connected to the SIKORA display and control system FIBER ECOCONTROL or to a line computer.
