Title: Optical amplifier control placement and its control method
Inventor: FEULNER MATTHIAS RICHARD
IPC: H04B10/29
Filed: 2000-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a device and its method for keeping constant relatively a gain per channel of an optical channel in an optical amplification WDM system even when an input intensity of an optical amplifier changes. SOLUTION: A gain of an optical amplifier is controlled by controlling a pumping intensity amount to be supplied to the optical amplifier as a function of a change of an optical input intensity to be measured in a feed forward monitoring route. The pumping intensity amount is adjusted according to a proportional relationship with respect to the measured input intensity. The pumping intensity is directly controlled, so that the gain of the optical amplifier is controlled in a time scale of less than microsecond from a detection of a change of the input intensity. Furthermore, a gain per channel in the amplified WDM signal is kept relatively constant irrespective of the change of the input intensity of the optical amplifier, thereby reducing substantially an intensity deflection in an optical channel in which the WDM signal is left behind.
