Optical fibers
FEM : Fiber Eccentricity Measurement
For the coated fiber eccentricity measurement
The
light propagation through the standard telecom optical fibre shows the asymmetry
of the coating assembly around the glass with a very high sensitivity
The FEM is used in case of spinning.
The independency of the layer eccentricities and index sensitivities to the temperature, do not allows measuring the eccentricities on 2 coating layers at once
Ξ Eccentricity measurement
- For standard optical fibres 245/125 between coating and glass.
- High sensitivity : ±0.2 µm amplitude..
- Measurement range : ±10µm amplitude, ±180° orientation.
- Fibre vibration and position measurement independent.
Ξ Other functions
- Field of measurement ±2mm.
- Local display for eccentricity and status.
- PC software for data management.
- Serial link RS232C : access to the internal parameters and measurement
results.
Ξ Outputs
- Analog asymmetry : ±10V
- Digital outputs. (Alarms, defects)
