1310/1550 nm Reduced Clad and Bend Insensitive Select Cutoff Single-Mode Fiber

Nufern’s 1310/1550 nm high-performance select cut-off single-mode fibers are optimized for use by component manufacturers in the telecommunications wavelengths. These application-specific fibers were developed for small form factor components. Nufern’s fibers offer exceptional uniformity and core/clad concentricity, very tight second mode cut-off tolerances, and tight bend radius specifications for applications in miniaturized fiber optic packages. These high-performance specifications result in superior strength, increased component reliability, improved production yields and reduced component manufacturer costs.
Applications
  • Small form factor components
  • Couplers
  • Optical switches
Features & Benefits
  • Exceptional uniformity and core/clad concentricity — low, consistent splice loss
  • Tight mechanical and optical tolerances — high component manufacturing yields
  • Higher proof test levels and 80 μm diameter — critical for long-term reliability in tight bend applications
