EDFA Definition. EDFA (Erbium-Doped Fiber Amplifier) is an optical device used to compensate optical signal attenuation caused by fibers and components, to increase optical transmission distance. Or. EDFA is an optical device that amplifies the optical signals without optoelectronic and electro optical conversion. Or

A typical setup of a simple erbium-doped fiber amplifier (EDFA) is shown in Figure 1. Its core component is the erbium-doped optical fiber , which is typically a single-mode fiber (or sometimes a few-mode fiber ).

2015年5月18日 · Erbium-doped fiber amplifier (EDFA) is an optical repeater device that is utilized to boost the intensity of optical signals being carried through a fiber optic communications system. An optical fiber is doped with the rare earth element erbium so that the glass fiber can absorb light at one frequency and emit light at another frequency.
