Cladding Diameter (µm)
Outer diameter of the glass cladding.
-
> 0.45
Cladding Numerical Aperture
High-NA cladding that captures and guides the pump light.
-
< 10.0
Background Loss @ 1200 nm (dB/km)
Low background losses.
-
375 ± 20
Coating Diameter (µm)
Outer diameter of the protective polymer coating.
