Broadband Operation: Compatible with the C-band (1530–1565 nm) and L-band (1565–1625 nm), EDFAs support dense wavelength-division multiplexing (DWDM) systems. An Erbium-Doped Fiber Amplifier (EDFA) is an optical amplifier that significantly enhances the strength of optical signals in fiber optic networks without converting them into electrical signals. Without an EDFA, a 100 km fiber link would lose around 25 dB of power—over 99% of its original strength. This article introduces optical amplification technologies.
