Nufern 3/125 Ultra-High NA Select Cut-Off Fiber

Nufern Ultra High NA fibers are excellent bridge fibers between high NA waveguides and low NA transmission fiber. Ultra High 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.

Applications
Fluoride and other non-silica fibers Planar waveguides Fiber tails for high NA sources

Features & Benefits
High numerical aperture-Bend insensitive fiber for miniature packages Thermally expandable core-Low splice loss to transmission fiber Small Mode Field Diameter-High coupling efficiency with Planar Waveguides
