How does an Optical Amplifier work?

  • Process that boosts the strength of optical signals to compensate for signal loss during long-haul transmission.

Why is Optical Amplification Necessary in Fiber Optic Communication?

  • Optical signals experience attenuation (loss of power) as they propagate through fibers due to factors like absorption and scattering.

  • Optical amplifiers counteract this attenuation, allowing signals to travel longer distances without significant degradation.

EDFA - Erbium-Doped Fiber Amplifer

  • An optical amplifier that uses erbium ions to amplify weak optical signals directly in the optical domain, primarily operating in the 1550 nm wavelength region.
