The development of the erbium-doped fiber amplifier (EDFA) revolutionized optical communications, eliminating fiber propagation loss as the primary limiting factor to transmission capacity, and enabling mass access to data transfer over inter-continental distances. By adopting wavelength division multiplexing (WDM) of high baud-rate (on-off keyed, OOK) channels, data signaling rates approaching 1 Tbit/s down a single fiber were ...
