What is a Fiber Optic Amplifier?

Fiber optic amplifiers are devices that amplify optical signals transmitted through optical fibers without converting them to electrical signals. They play a crucial role in long-distance optical communication systems, allowing signals to travel over long distances without losing strength. The optical fibers are usually glass fibers that are doped with rare earth ions such as erbium, neodymium, ytterbium, praseodymium, or thulium. This active dopant is pumped with a laser such as a fiber-coupled diode laser. The pumped light propagates through the fiber core together with the signal to be amplified. Fiber optic amplifiers are widely used in telecommunications, cable television, and data transmission, as well as in scientific research and medicine. Figure 1 shows a simple fiber amplifier diagram.

Figure 1: Simple diagram of a fiber optic amplifier

An optical fiber transmission system uses multiple communication devices, like optical transmitters and receivers. The transmission loss of light passing through the optical fiber is very small (less than 0.2 dB per km) within a light wavelength of 1,550 nm. But for long-distance transmission, the transmission loss is higher. Since the length of the optical fiber is stretched at distance as long as 10 km or 100 km, the transmission loss is amplified. In this case, the light signal propagating a long distance through optical fiber becomes extremely weak. Hence it is necessary to amplify the light using a fiber optic amplifier. An optical fiber amplifier is inserted at specific locations where the signals are weak to boost optical signals in a communication system. These boosted signals can be successfully transmitted through the fiber optic cable. In large networks, a series of fiber optical amplifiers are placed in a sequence to cover the entire network link. There are different types of fiber optic amplifiers: 

  • Erbium-Doped Fiber Amplifier (EDFA)
  • Semiconductor Optical Amplifier (SOA)
  • Fiber Raman Amplifier (FRA)
  • Optical Parametric Amplifier (OPA)
  • Benchtop Amplifier
  • CYFA Amplifier 
  • Power Amplifier
  • Tapered Amplifier 
  • TDFA Amplifier
  • Travelling Wave Amplifier
  • Ultrafast Amplifier
  • YDFA Amplifier

Applications of Fiber Optic Amplifier

Fiber optic amplifiers are mostly used in optical fiber communications over large distances, where signals need to be amplified. In optical fiber communications, light from a fiber can be easily sent into a fiber optic amplifier and the amplified light can be sent into further transmission fiber. High-power fiber optic amplifiers are used in laser material processing. EDFAs are used in metro and access networks to amplify signals for distribution to multiple users and in scientific research, particularly in spectroscopy.

Fiber optic amplifiers can amplify ultrashort light pulses. Such amplifiers store a considerable amount of energy, which can then be released as an intense pulse within short durations. Short pulse durations of 100 fs or less are possible due to the considerable gain bandwidth, which is the maximum amount of data transmitted over an internet connection in a given amount of time.

Raman amplifiers are typically used in optical communications systems, such as fiber-optic networks. They are particularly useful in long-haul and ultra-long-haul communications systems, where the signal losses due to attenuation and dispersion are significant. Raman amplifiers can be used to amplify signals over distances of up to several thousand kilometers, making them a key component in the development of high-capacity optical networks.

Semiconductor optical amplifiers can be used in wavelength division multiplexing (WDM) systems, optical switching, and sensing. In WDM systems, multiple optical signals are transmitted over a single optical fiber, and SOAs are used to amplify each signal at a specific wavelength. In addition, SOAs can be used in optical switching applications, where they are used to control the flow of optical signals in a network. They can also be used in sensing applications, where they are used to detect changes in the intensity of an optical signal.
