Nufern Ultra-High NA Select Cutoff Single-Mode Fiber 4

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
