Abstract :
We theoretically investigate various configurations of erbium-doped fiber amplifier (EDFA) for simultaneously amplifying AM-VSB analog CATV signal and multiple optical digital baseband signals in hybrid wavelength division multiplexing (H-WDM) systems. A total of nine EDFA configurations is examined and compared. The investigation provides the best EDFA configuration selection to design both H-WDM power and in-line amplifiers.
