Frequently Asked Questions

It has a higher GeO2 concentration (75% vs. 50%), giving a higher refractive index contrast (Δn = 0.11 vs. 0.074) and a smaller core (2.2 µm vs. the 4×3 µm elliptical core), for applications needing stronger nonlinear confinement.

Minimum loss, around 20 dB/km, occurs in the 1700–1850 nm band.

No — typical splicing loss to ordinary fiber is around 1 dB, a manageable figure despite the high GeO2 concentration.
