980 nm Reduced Clad Select Cutoff Single-Mode Fiber
Nufern’s 980 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 pump diode pigtails, unique delivery for components, and couplers. Available in 80 μm and 125 μm form factors, Nufern’s 980 nm fibers offer exceptional uniformity and core/clad concentricity specifications, very tight second mode cut-off tolerances, and tighter bend radius 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.
6.8 ± 0.5 µm @ 1550 nm
Geometrical & Mechanical Specifications
Bend Loss: The Bend Loss at 980 nm (100 turns as LTBR) is <0.001 dB, by design.
Bend Radius: The Bend Radius for 0.05 dB/100 turns at 1550 nm is 15 mm, by design.
Bend Radius: The Bend Radius for 0.05 dB/100 turns at 980 nm is much less than LTBR, by design.
Coating Requirements: UV Cured, Dual Acrylate.
