                     nufern掺铒光纤L波段小包层EDFL-980-HP-80

EDFL-980-HP-80 L-Band Reduced Clad Erbium-Doped Single-Mode Fiber

Nufern high performance L-Band Erbium-doped fibers are designed for use in L-band amplifiers and compact ASE sources. The 80 μm version is a reduced-cladding fiber ideal for small form-factor devices. All Nufern erbium-doped fibers are fabricated with a proprietary doping technology and have highly consistent and reproducible spectroscopy, ensuring intra-lot and lot-to-lot uniformity. These fibers are extensively characterized and accompanied by lot specific data.
