Frequently Asked Questions

It has substantially higher core absorption (15±2 dB/m vs. 6±1 dB/m at 980 nm), which lets you build a shorter amplifier coil for the same pump power without giving up conversion efficiency.

Typical pump-to-signal conversion efficiency is around 11±4%.

Yes — both use the same 4 µm core / 125 µm cladding geometry, so switching between them for different length/absorption trade-offs doesn't require redesigning splice or packaging tooling.
