CNI pure
silica core fibers are optimized for use at visible wavelengths from 400 up to
1550 nm. These high-performance fibers were developed for applications such as RGB components requiring couplers, diode pigtails and delivery needs. The
pure silica core fibers were designed for more demanding applications that
require lower attenuation and higher resistance to radiation and color center
formation compared to germanium-doped fibers. |
