Abstract

Transient response of erbium-doped fiber amplifier (EDFA) is studied in an external-modulated analog link. Double tones representing as transmitted radio frequency (RF) and dither signals are introduced.

Extra modulation is generated owing to EDFA’s transient response caused by low-frequency dither signal. Therefore, the parasitic modulation is superposed to the output signals and may significantly affect in-band electrical spectrums. Analytical and numerical solutions are both given, which agree well with experimental results.

This manuscript indicates that suitable dither signal should be selected to maximize carrier to intermodulation ratio. In-band spurious free dynamic range is optimized in the meantime.
