Photosensitive Single-Mode Low-NA Fiber - 1

Photosensitive Single-Mode Fibers Nufern photosensitive fibers are designed to reduce grating-writing times associated with industry-standard telecommunication fiber and can be easily spliced. These photosensitive fibers provide cost-savings for grating-writing because customers can write highly repeatable, quality gratings in a short time. Typical Applications Features & Benefits • WDM • Enhanced photosensitivity — Shorter grating writing time • Gain flattening filters • Mode-matched to transmission fibers — Low splice loss • Dispersion compensators • Tightly controlled specifications — Excellent uniformity • Pump stabilizers Optical Specifications Operating Wavelength Operating Wavelength (nominal) Core NA Mode Field Diameter Cutoff Core Attenuation GF1 GF1AA GF3 GF1B 1500 – 1600 nm N/A 0.130 9.3 ± 0.5 µm @ 1310 nm 10.5 ± 1.0 µm @ 1550 nm 1260 ± 75 nm N/A 1500 – 1600 nm N/A 0.130 10.5 ± 0.8 µm @ 1550 nm 1500 – 1600 nm N/A 0.160 7.5 ± 0.5 µm @ 1550 nm N/A 1550 nm 0.130 10.4 ± 0.8 µm @ 1550 nm 1350 ± 100 nm N/A 1350.00 ± 50.00 nm N/A 1260 ± 100 nm ≤ 0.50 dB/km @ 1550 nm 125.0 ± 1.5 µm 9.0 µm 250.0 ± 20.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 12 mm ≥ 25 mm ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.5 µm 8.5 µm 250.0 ± 20.0 µm < 5.0 µm ≤ 1.00 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 12 mm ≥ 25 mm ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.0 µm 7.0 µm 245.0 ± 15.0 µm < 5.00 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 12 mm ≥ 25 mm ≥ 100 kpsi (0.7 GN/m²) 125.0 ± 1.0 µm 9.0 µm 245.0 ± 15.0 µm < 5.0 µm ≤ 0.50 µm UV Cured, Dual Acrylate -55 to 85 °C ≥ 12 mm ≥ 25 mm ≥ 100 kpsi (0.7 GN/m²) Geometrical & Mechanical Specifications Cladding Diameter Core Diameter Coating Diameter Coating Concentricity Core/Clad Offset Coating Material Operating Temperature Range Short Term Bend Radius Long Term Bend Radius 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.
