Smart Product Number: 980M-HP-80
Nufern 980 nm Reduced Clad Medium-NA 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 cut-off 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.
