Inside the technology

Nine tools to explore your technical choices

Open Scientific Studio

Select a layer to discover its role.

Core

The central region guides light. In an active fiber, it can contain dopants that enable optical amplification.

Cladding

The glass surrounding the core helps guide light through the difference in refractive index.

Coating

The outer polymer layer protects the glass against mechanical damage and makes the fiber easier to handle.
