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
