Abstract :
A low-noise broad-band EDFA with a seamless amplification band in both the C- and L-bands is successfully developed by using erbium-doped tellurite fibers. This EDFA exhibits a broad amplification bandwidth of 70.8 nm (from 1532.7 to 1603.5 nm) with a gain excursion of less than 1.5 dB, an average gain of 24.3 dB, and a noise figure of less than 6 dB (less than 5.3 dB for extracting the insertion loss of the input end).
