The electrical signals are then converted into optical signals using a transmitter.
The optical signals are then multiplexed together, combining multiple wavelengths onto a single fiber.
The multiplexed signals are transmitted over long distances t...
There are three types of amplifiers used in DWDM: erbium-doped fiber amplifiers (EDFAs), Raman amplifiers, and semiconductor optical amplifiers (SOAs).
Erbium-doped fiber amplifiers (EDFAs) are the most commonly used amplifiers in DWDM systems.
Raman amplifiers use stimulated Raman scattering to amplify the signal.
Semiconductor optical amplifiers (SOAs) are compact and can be integrated into other optical components.
