Nufern 980 nm Reduced Clad Medium-NA 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 ?m and 125 ?m 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.

Applications
Pump Diode Pigtails Metro components Small form factor components Couplers

Features & Benefits
Exceptional uniformity and core/clad concentricity - Low, consistent splice loss to telecom components Extremely tight second mode cutoff tolerance - High yield coupler manufacturing Higher proof test levels - Critical for long-term reliability in tight bend applications
