C-Band Reduced Clad Erbium-Doped Single-Mode Fiber

Nufern’s high performance C-Band Erbium-Doped 980-HP Fibers (EDFC-980-HP and EDFC-980C-HP-80) 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. Both types can be powered with 980 nm or 1480 nm pumps. All Nufern erbium-doped fibers are fabricated with a proprietary technology and have highly consistent and reproducible spectroscopy.
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
