Smart Product Number: PWG1-XP
Planar Waveguide Single-Mode Fiber
Nufern extra high-performance Planar Waveguide Fiber is part of the NuBRIDGE™ fiber family and provides a solution to the splicing challenges for high NA waveguiding structures. Industry developments indicate the call out for easy interfacing of new planar waveguide (PWG) technology with existing fiber infrastructures. Planar Waveguide Fiber is an excellent bridge fiber between high NA planar waveguides and low NA transmission fiber. This fiber allows outstanding optical coupling with planar waveguides. In addition, the composition of PWG1-XP is tailored to thermally expand the core during splicing and thus achieve low splice loss to transmission fibers.

Comments
Bend Loss: Bend Loss at 1550 nm for 100 turns and a 13 mm radius is <0.001 dB (nominal).
Bend Radius: Bend Radius for 0.05 dB per 100 turns at 1550 nm is much less than the LTBR.
Coating Requirements: UV Cured, Dual Acrylate
