Abstract
For WDM transmission systems, Optical Fiber Amplifiers employing novel High-speed AGC and Tone-Signal ALC functions are proposed. Based on a both wavelength and time resolved simulation technique, the amplifier repeater is designed and fabricated. The AGC/ALC scheme can suppress the transient power fluctuation of a surviving channel caused by adding or dropping all other channels (32ch - 1ch) less than 0.45dB and keep output power constant over 9dB input power range.
