High Temperature Fibre (HTF)

Data transmission, high power laser delivery and sensors require special reliability at demanding environment conditions. A special challenge is the changing temperature, extreme heat or extreme cold conditions for a fibre when used as fire detector, temperature sensor or for data transmission in certain special industrial applications. YOFC offers HTF for medium and high temperature environment requirements with the temperature up to 300 ℃.
