Abstract
L-band tellurite-based EDFAs (EDTFAs) have an advantage over silica-based EDFAs (EDSFAs) in that EDTFAs have a 50-nm gain bandwidth (1560-1610 nm) whereas the EDSFA gain bandwidth is only 30 nm (1570-1600 nm) [1]. EDTFAs are also attractive in that the gain band can be extended to the 1610-1620 nm region, which is impossible with EDSFAs [2].
