Some typical performances obtained with an AGC PDFA are presented here  (for more details, please refer to ECOC 2008 Proceedings, P1.13). As it can be seen,  the gain excursions are within a  0.5-dB range for all conditions and at any time (the  spikes at both edges are caused by calculation errors).  Optical surge characteristics Burst signals with shorter guard time induce optical surges at the rising edge of the  output signal as it can be seen while using conventional optical amplifiers. The AGC  optical amplifier is able to minimize the distortions and can offer optical surge-free  performances.  Transient characteristicsof the ALC mode Based on the feedforward control of a high-speed acousto-optic VOA, automatic  level control operation is possible for input signals with rapid changes and wide  dynamic range as well as short guard time between burst signals (for further details,  see OFC/NFOEC 2009 Proceedings, OTuH4).
