Definition
Amplifying repeater links are a vital aspect in maintaining high performance and in providing a route to low cost in optical communication networks. Through adequate reamplification at multiple stages along a transmission path, an optical signal can maintain signal integrity over a much greater distance between points at which the optical signal is finally converted into an electronic signal.

A fiber amplifier amplifies an optical light signal passing through it without converting it into electricity in between – unlike regenerators, which first convert light into electricity, amplify it and finally convert it back into light. In a fiber amplifier, the signal to be amplified triggers a stimulated emission in an (usually doped) optical fiber. The optical power for this stimulated emission is provided by pumping lasers (most often laser diodes), which excite the dopant atoms to a higher level – with the input signal then stimulating these atoms to release the excess energy as photons of the same phase and wavelength. Hence, in principle, a fiber amplifier works like a laser without a resonator or mirror.

Fiber amplifiers are offered as single or multi-channel components with fiber pigtails, but also as modules in which the inputs and outputs can be realised not only with fiber pigtails but also with common fiber connectors. In addition to the actual amplifiers, the electronics for the pump diodes as well as other functions such as stabilisation, filters, power monitoring, etc. are integrated in these modules.

Fiber amplifiers are available based on fibers doped with Erbium (Er), Ytterbium (Yt), or other elements. Erbium-Doped Fiber Amplifiers (EDFAs) are the most common, but Ytterbium- (YDFAs) and Ytterbium/Erbium-Co-Doped (YEDFAs) Fiber Amplifiers are also often used. The main areas of application are fiber-optic transmission links of great length or widely branched fiber-optic networks. EDFAs amplify all channels of a Wavelength Division Multiplex (WDM) signal simultaneously, while a regenerator has to perform optical/electrical conversion for each channel.

Raman amplifiers are based on stimulated Raman scattering; the irradiated high-intensity pump wave is scattered by the optical fiber molecules. In principle, this process can also take place spontaneously, but here it is stimulated by the light signal to be amplified in the (Silica) fiber. Last but not least, with a combination of several pump sources, Raman amplifiers usually have a high bandwidth compared to EDFAs, including the C- and L-bands. The amplification range can be adjusted via the pump wavelength(s). Because the entire fiber represents the Raman medium, the amplification takes place over the entire fiber length, which can lead to an improved signal-to-noise ratio.
