High Temperature Silica Fiber

 

High temperature resistant optical fiber is mainly used for sensing, communication, lighting and other fields under high temperature and high humidity and other harsh environments. The coating modulus is wear-resistant and corrosion-resistant; the gas-containing acrylic resin can ensure the long-term stable use of optical fiber below 150℃, and the polyimide ester coating can make the optical fiber work stably in the environment below 300℃.

Note: Due to the hard material of high temperature resistant coating, it should be loosely wound on a disc with diameter greater than 36cm for attenuation test. In addition to the above products, we can also apply high-temperature coatings on various core sizes (e.g. 200 μm, 300 μm, 330 μm, 400 μm, 440 μm, etc.) with different core/package ratios and different numerical apertures according to customer requirements. Code naming rule Take HT-200/220-240-P for example, HT fiber type high temperature resistant, 200/220 core/cladding diameter, 240 coating diameter, P coating material.
