(engineering)
An optoelectronic amplifier in which the electric input signal is converted to light, amplified as light, then converted back to an electric signal for the output.

optical amplifier

A device that boosts light signals in an optical fiber network. Unlike regenerators, which have to convert light to electricity in order to amplify it and then convert it back again to light, the optical amplifier amplifies the light signal itself. Developed in the late 1980s, the erbium-doped fiber amplifier (EDFA) was the first successful optical amplifier. See EDFA.

where [L.sub.eff] = [1-exp(-[[alpha].sub.p]L)]/[[alpha].sub.p] represent the effective length of the Raman fiber amplifier, where [g.sub.R] represents Raman gain coefficients, [[alpha].sub.p] is the pump cross-sectional area, as is the fiber loss, [P.sub.0] is the input power, and [P.sub.s](0) is the signal power a L = 0.
Also, the larger the output power of the optical fiber amplifier is by cascading the other optical fiber amplifier, the larger the backscattered light is.
Raman fiber amplifiers (RFAs) have found numerous applications in long haul and ultra-long haul optical communication systems, due to wide gain bandwidth and wavelength flexibility of stimulated Raman scattering (SRS).

One of the most usable in the contemporary submarine and long-haul terrestrial networks is the distributed Raman amplifiers (DRAs) used stimulated Raman scattering (SRS) effect, which has many advantages: stimulated Raman amplification can occur in any fiber at any signal wavelength by proper choice of the pump wavelength; the Raman gain process is very fast and the effective noise figure (NF) of DRA is smaller than the one of Erbium-doped fiber amplifier (EDFA) and/or the semiconductor optical amplifier [2,3].
Erbium doped fiber amplifier (EDFA) is considered as the most deployed fiber amplifier as its amplification window coincides with low loss telecommunication windows at 1550 nm.
