Ultra-High NA Select Cutoff Single-Mode Fiber
Nufern Ultra-High NA fibers are part of the NuBRIDGE™ fiber family and 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.
