TECHNICAL FAQ

Questions for application planning

What are the roles of 2716 and 3220?

2716 is the primary coating and 3220 is the protective outer coating in the single-mode fiber coating system.

Which process details should be provided?

Share the glass diameter, target coating dimensions, line speed, application method, lamp setup and finished-fiber test plan.

Why should both layers be evaluated together?

Primary and outer coatings are applied as a system, so cure, geometry, adhesion and finished-fiber behavior should be checked together.
