Frequently Asked Questions

This variant uses a fluorine-doped (depressed) cladding instead of a plain silica cladding, which changes the refractive-index profile — useful for specific mode-field or dispersion design needs, while retaining the same copper/carbon hermetic coating system.

The same as FORC-Photonics' standard copper-coated fiber: −196°C to +600°C (short-term), with a carbon underlayer for improved hermeticity and mechanical strength.

Two variants: OK-6/125F-C/Cu (6.7 µm core) and OK-9/125F-C/Cu (9.1 µm core).
