Abstract :
We demonstrate the performance of linear optical amplifiers (LOAs) in a dynamic and reconfigurable wavelength-division-multiplexing (WDM) system. Eight WDM channels, each channel running at 10 Gb/s, are transmitted through two cascaded LOAs. Power transient immune add-drop capability is demonstrated by switching four of the eight channels at rates of 10-100 kHz without affecting the bit-error-rate (BER) or eye pattern. The same WDM system trial using erbium-doped fiber amplifiers instead of LOAs shows identical BER performance for the eight-channel case, but deteriorated eye patterns and bit error penalties for the channel ADD-DROP configuration.
