Abstract
Interest behavior of the flattened dynamic gain of an erbium-doped fluorozirconate fiber amplifier is demonstrated in a lightwave CATV system including a 50-channel subcarrier multiplexer. Using two analog distributed-feedback (DFB) laser diodes, one with a relatively high chirp and the other with a very low chirp, a comparison between amplifiers made of erbium-doped silica and fluoride fiber demonstrates the significant influence of the laser FM response when the spectral dynamic gain of the amplifier is not constant.Keywords
