TECHNICAL FAQ

Questions for application planning

What are the roles of 2816 and 3320?

2816 is the primary coating and 3320 is the protective outer coating in the multimode fiber coating system.

Should cable construction be included in evaluation?

Yes. Coated-fiber handling and cable structure can affect the final mechanical and optical result.

What should be shared for material selection?

Provide the fiber and coating geometry, drawing and cure setup, downstream process and finished-fiber acceptance tests.
