L-Band Erbium Doped Fibers
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.
Typical Applications
Features & Benefits
• L-band amplifiers
• Highly consistent and reproducible spectroscopy — no need to batch matching GFFs
• Compact ASE sources
• Excellent core concentricity — low splice loss
• Small form factor packages
• Detailed lot-specific characterization data — compatible with modeling programs
