Typical Applications • WDM • Gain flattening filters • Dispersion compensators • Pump stabilizers 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. Features & Benefits • Enhanced photosensitivity — Shorter grating writing time • Mode-matched to transmission fibers — Low splice loss • Tightly controlled specifications — Excellent uniformity Optical Specifications Operating Wavelength Core NA Mode Field Diameter Cutoff Core Attenuation 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 250.0 ± 20.0 pm < 5.0 pm s 0.50 pm UV Cured, Dual Acrylate -55 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 250.0 ± 20.0 pm < 5.0 pm s 1.00 pm UV Cured, Dual Acrylate -55 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 245.0 ± 15.0 pm < 5.00 pm s 0.50 pm UV Cured, Dual Acrylate -55 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) 245.0 ± 15.0 pm < 5.0 pm s 0.50 pm UV Cured, Dual Acrylate -55 to 85 °C > 12 mm > 25 mm > 100 kpsi (0.7 GN/m2) fJUFERN 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.
