Frequently Asked Questions

It's specifically designed to achieve the highest pump-to-signal conversion efficiency in telecommunication erbium-doped fiber amplifiers (EDFAs).

It's characterized for 980 nm pumping (core absorption 6±1 dB/m), the standard pump wavelength for telecom EDFAs, alongside 1532 nm signal-band absorption of 10±3 dB/m.

Core nonconcentricity is held below 0.5 µm, which keeps splice loss to standard single-mode fiber low and consistent.
