Fluoride fiber technology

22.jpg

Fluoride fiber is multi-composite glass optical fiber composed of several heavy metal fluorides, and many different types of fluoride fibers exist depending on the material composition. Fluoride fibers have many unique characteristics that are not enabled by silica fiber, such as a wider operating wavelength range, as well as a higher emission efficiency when doped with rare-earth elements.
