Ultra-High NA Select Cutoff Single-Mode Fiber 7 - 1

Ultra-High NA Single-Mode Fibers Nufern Ultra-High NA fibers are excellent bridge fibers between high NA waveguides and low NA transmission fiber. UltraHigh NA fibers provide excellent coupling efficiencies to high NA waveguides. In addition, the composition of Ultra-High NA fibers are tailored to thermally expand the core during splicing thus achieving lower splice loss to transmission fiber. Typical Applications Features & Benefits • Fluoride and other non-silica fibers • High numerical aperture — Bend insensitive fiber for miniature packages • Planar Waveguides • Thermally expandable core — Low splice loss to transmission fiber • Fiber tails for high NA sources • Small Mode Field Diameter — High coupling efficiency with Planar Waveguides Optical Specifications Operating Wavelength Core NA Mode Field Diameter Cutoff UHNA1 UHNA3 UHNA4 UHNA7 1100 – 1600 nm 0.280 4.0 ± 0.3 µm @ 1310 nm 4.8 ± 0.3 µm @ 1550 nm 3.3 ± 0.3 µm @ 1100 nm 1000 ± 50 nm 960 – 1600 nm 0.350 3.3 ± 0.3 µm @ 1310 nm 4.1 ± 0.3 µm @ 1550 nm 2.6 ± 0.3 µm @ 1100 nm 900 ± 50 nm 1100 – 1600 nm 0.350 3.3 ± 0.3 µm @ 1310 nm 4.0 ± 0.3 µm @ 1550 nm 2.6 ± 0.3 µm @ 1100 nm 1050 ± 50 nm 1500 – 2000 nm 0.410 3.2 ± 0.3 µm @ 1550 nm 125.0 ± 1.0 µm 2.5 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 ± 1.0 µm 1.8 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 ± 1.0 µm 2.2 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 ± 1.0 µm 2.4 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) 1450 ± 50 nm 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.
