Smart Product Number: 980-XP
Nufern 980 nm Select Cutoff Single-Mode Fiber
Nufern 980 nm high-performance select cutoff single mode fibers are optimized for use by component manufacturers at 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, tight tolerance core/clad concentricity and second mode cutoff specifications. These fibers are designed for tighter bend radius applications including miniaturized fiber optic packaging. These high performance specifications result in superior strength, increased component reliability, improved production yields, and reduced component manufacturer costs. The -XP version offers the tightest tolerance specifications for more demanding applications.
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.
