Advanced Optical Components – Erbium-doped Fiber Amplifier (EDFA)

Many fiber optic applications, such as long-haul DWDM systems, require amplification of the optical signal. In the past, this entailed using expensive electronic repeaters at intermediate points every 100 km. Today’s modern long-haul DWDM systems use several advanced optical components to replace multiple repeaters with a single optical device. These optical devices which are called […]
