WDM burst mode signal amplification by cascaded EDFAs with transient control
Abstract:
We demonstrate that WDM burst signals are amplified with suppressed gain transients in cascaded erbium-doped fiber amplifiers (EDFAs) with fast electrical feedback control. In a recirculating loop experiment, the gain excursion is suppressed to 5.1 dBp-p after 45 EDFAs while the excursion is 28 dBp-p after 5 EDFAs without the gain control. Spectral hole burning is a main limiting factor for the transient suppression. The effect of the gain control is also verified in a transmission experiment at 10 Gb/s.
