Cat No:OFDF-0038
The radiation-resistant polarization-maintaining erbium-doped fiber (PM-EDF) offers excellent resistance to high-energy ionizing radiation, effectively reducing the impact of radiation on erbium-doped fibers. It also features high birefringence and excellent polarization-maintaining performance. The fiber provides high uniformity, can be pumped at 980 nm or 1480 nm, and allows low-loss splicing with standard communication fibers.
