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 Optical Specifications Operating Wavelength Core NA Mode Field Diameter Cutoff Core Attenuation Core Absorption EDFL-980-HP EDFL-980-HP-80 EDFL-1480-HP 1565 – 1625 nm 0.250 5.5 ± 0.5 µm @ 1550 nm 920 ± 50 nm ≤ 15.0 dB/km @ 1200 nm 25.0 ± 2.0 dB/m near 1530 nm 18.5 ± 11.5 dB/m near 980 nm 1565 – 1625 nm 0.250 5.5 ± 0.5 µm @ 1550 nm 920 ± 50 nm ≤ 15.0 dB/km @ 1200 nm 25.0 ± 2.0 dB/m near 1530 nm 18.5 ± 11.5 dB/m near 980 nm 1565 – 1625 nm 0.250 5.3 ± 0.5 µm @ 1550 nm 1420 ± 50 nm ≤ 15.0 dB/km @ 1200 nm 15.0 ± 3.0 dB/m at 980 nm 30.0 ± 3.0 dB/m near 1530 nm 125.0 ± 1.0 µm 2.8 µm 245.0 ± 10.0 µm < 5.0 µm ≤ 0.30 µm UV Cured, Dual Acrylate -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 80.0 ± 1.0 µm 2.8 µm 165.0 ± 10.0 µm < 5.0 µm ≤ 0.30 µm UV Cured, Dual Acrylate -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) 125.0 ± 1.0 µm 4.5 µm 245.0 ± 10.0 µm < 5.0 µm ≤ 0.30 µm UV Cured, Dual Acrylate -40 to 85 °C ≥ 200 kpsi (1.4 GN/m²) Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Coating Concentricity Core/Clad Offset Coating Material Operating Temperature Range Prooftest Level 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.
