1310/1550 nm Bend Insensitive Medium-NA Select Cutoff Single-Mode Fiber
Nufern’s 1310/1550 nm high-performance select cutoff 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 cutoff 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.
7.6 ± 0.6 µm @ 1550 nm
≤ 0.50 dB/km @ 1550 nm
Geometrical & Mechanical Specifications
Bend Radius: The Bend Radius at 1310 nm for 0.05 dB/100 turns (nominal) is much less than LTBR, by design.
Coating Requirements: UV Cured, Dual Acrylate
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
- Small form factor components
- Optical switches
