PM Radiation Resistant Er-Doped Fiber

CJ Photonics PM Er-Doped Fiber has excellent radiation resistance, which can effectively reduce the impact of high-energy ion radiation on Er-doped fibers. At the same time, it has high birefringence and excellent polarization retention characteristics. This fiber optic has good consistency. 980nm or 1480nm series pumps can be used to achieve low loss connection with communication fibers.
