460 nm Select Cutoff Single-Mode Fiber

Nufern visible wavelength fibers are optimized for use from 400 up to 900 nm. The high-performance fibers were developed for applications such as RGB components requiring generation of couplers, diode pigtails and unique delivery needs. These fibers feature greater proof test levels and a tigher second mode cutoff tolerance than standard fibers, resulting in higher strength, increased component reliability, better production yields and reduced costs for component manufacturers.
Applications
  • Diode Pigtails
  • Compact UV sources
  • RGB components
  • Couplers
Features & Benefits
  • Superior fiber geometrical tolerances — Improved connectorization and coupling performance
  • Extremely tight second mode cutoff tolerance — Enhanced component reproducibility
  • Higher proof test level — Greater reliability for tight bend applications
