Frequently Asked Questions

Its small core and high NA (~0.3) concentrate optical power to boost nonlinear effects like stimulated Raman scattering, while still keeping optical loss below 5 dB/km at 1550 nm.

HNLF has a large negative dispersion of less than -50 ps/nm/km at 1550 nm, with a zero-dispersion wavelength above 2300 nm, useful for dispersion-compensation applications.

Yes — a pure-GeO2-core version with core NA greater than 0.6 is available on request, along with a polarization-maintaining (PM) version.
