Product Description

Nufern 980 nm Select Cut-Off

Single-Mode Fibers

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.

 

Typical 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
