Development of broadband optical fiber amplifiers in the form of erbium-doped fiber amplifiers (EDFAs), which led to the birth of the era of wavelength division multiplexing (WDM) technology in the mid-1990s, ushered in a revolution in optical fiber communication. WDM technology, more precisely known as dense WDM (DWDM) technology, involving simultaneous transmission of at least four wavelengths in the 1550-nm low-loss wavelength window through one single-mode fiber has indeed resulted in an enormous increase in ...
