❍ ❍ 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.
