TECHNICAL FAQ

Questions for application planning

Are numerical performance limits claimed on this page?

No. The page identifies the 3016 / 3020 product route. Application limits should be defined and verified on the intended fiber and process.

Why should coating geometry be part of the evaluation?

The coating surrounds a geometry-sensitive fiber, so layer dimensions and concentricity should be included in finished-fiber inspection.

What should be shared for a hollow-core coating discussion?

Provide the fiber structure, coating dimensions, draw and cure setup, handling environment and required finished-fiber tests.
