Dynamic performance of the all-optical gain controlled EDFA cascade in multiwavelength optical networks

摘要

The authors present experimental results of using the all-optical gain-clamped EDFA for protecting surviving channels in a wavelength-division-multiplexed network in which many EDFAs are used in cascade. In particular, the effects of relaxation oscillations from the gain-clamped EDFAs on transmission performances of surviving channels are discussed.
