80um high NA singlemode fiber

Acrylate coated
High NA
High temperature acrylate coated
Polyimide coated
Reduced cladding
Singlemode
80um HNA

Our line of 80um reduced cladding fiber are ideal for installations in compact systems and for applications where the fiber is bent tightly.

With its high numerical aperture, these fibers are less sensitive to tight bends.

The fibers are available in polyimide, high temperature acrylate and standard acrylate coatings. Contact us for cabling options.
