C-Band Erbium Doped 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 urn 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 Typical Applications C-band amplifiers 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 Mode Field Diameter 5.8 ± 0.5 pm @ 1550 nm 5.8 ± 0.5 pm @ 1550 nm Core Attenuation < 10.0 dB/km @ 1200 nm < 15.0 dB/km @ 1200 nm Core Absorption 6.00 ± 1.00 dB/m near 1530 6.50 ± 3.50 dB/m at 980 nm Geometrical & Mechanical Coating Material UV Cured, Dual Acrylate UV Cured, Dual Acrylate Operating Temperature Range -40 to 85 °C -40 to 85 °C Prooftest Level > 200 kpsi (1.4 GN/m2) > 200 kpsi (1.4 GN/m2) 7 Airport Park Road, East Granby, CT 06026 • 860.408.5000 • Toll-free 866.466.0214 • Fax 860.844.0210 E-mail info @ nufern.com • www.nufern.com Nufern products are manufactured under an ISO 9001:2008 certified quality management system.
