❍ Figure 6: Fibre strength test for new material single coat optical
fibre samples at 150°C and 180°C
It shows the new material single coat fibre strength after
temperature aging at 150°C and 180°C. Fibre strength
did not drop after 1,000 hours of elevated temperature
exposure for all samples.
All of these results demonstrate good long-term stability
for temperatures below 180°C for optical fibres made with
the newly developed coating material.
4 Conclusions
A new mid-temperature acrylate type coating material
was developed. Optical fibre samples made with a
single coat layer of the new material (coating diameter of
200 μm) were tested in dynamic and isothermal TGA
tests demonstrating superior performance in comparison
with the existing commercial mid-temperature acrylate
type coatings.
Long-term temperature aging tests in normal atmosphere
at temperatures up to 200°C demonstrated stability of
optical fibre attenuation and fibre mechanical strength.
