Transient Control
A fast control algorithm is implemented in ROADM systems to handle rapid and
potentially large variations in channel power, e.g., due to fiber cuts. This form of
transient control will suppress the channel performance degradation that may
occur between the time of the fault and the time required for the steady-state
control to adapt. In EDFA systems, transient control is usually implemented
through a constant gain amplifier fast control algorithm. The speed required of
the amplifier control is determined by the minimum rise time of the channel power
excursions during transient events. If a set of channels loading an amplifier is
rapidly ...
