Abstract
The interest of the flattened dynamic gain of an erbium-doped fluorozi rconate fiber amplifier is demonstrated in a lightwave CATV system inc luding a 50-channel subcarrier multiplex. Using two analog DFB laser d iodes, one with a relatively high chirp, the other with a very low chi rp, a comparison between amplifiers built with 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 const ant.
