For Use in Optical Ampliers and Fiber Lasers

Manufactured with Corning’s patented outside vapor deposition (OVD) process, Corning

ER specialty fibers set the world

standard for uniformity and reliability. Corning offers Erbium-doped fibers with or without hermetic coating. The hermetic

coating offers significant advantage with respect to mechanical reliability and resistance to hydrogen-induced optical

attenuation degradation. These Erbium-doped fibers have a proven track record in state-of-the-art optical amplifiers, and exhibit

consistently low splice loss when coupled with fibers such as Corning

HI 1060 FLEX, Corning

HI 980, and Corning

SMF-28e+

optical fiber. Erbium-doped fibers designs are available for conventional C-band, L-band, and reduced clad (80 µm) applications.

Features

▪
