Radiation Resistant Er-Doped Fiber

CJ Photonics Radiation Resistant Er-Doped Fiber has good radiation resistance characteristics, which can effectively reduce the impact of high-energy ion radiation on Er-doped fibers. This fiber has good consistency. It can be pumped at 980 nm or 1480 nm to achieve low loss connection with communication fibers.
