3.1.1 The wavelength-division multiplexing revolution

In the early 1990s, the first doped-fiber optical amplifiers appeared, providing the amplification function that had been lacking in optical transmission. This change led to the emergence of Wavelength Division Multiplexing (WDM), the principle of which is to transmit on a single optical fiber not a single modulated wavelength, but a set of channels making it possible to occupy the available bandwidth infinitely more efficiently. A single fiber...
