C-Band Erbium Doped Fibers
Nufern’s high performance C-Band Erbium-Doped 980-HP Fibers are designed for use in single and multi-channel C-band
amplifiers and ASE sources. The 80 µm version is suitable for small form-factor amplifiers and metro amps. The “HI” version
is designed to achieve the highest possible optical efficiencies in applications where available pump power is limited.
All Nufern erbium-doped fibers are fabricated with a proprietary technology and have highly consistent and reproducible
spectroscopy
Typical Applications
• Single and multi-channel
C-band amplifiers
• ASE sources
• Small form factor amps
• Metro amps
Features & Benefits
• Highly consistent and reproducible spectroscopy — high manufacturing yields when matching to a GFF
• Excellent core concentricity — low splice loss to single-mode fibers
• High aluminum concentration — inherent gain flatness
