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.optical amplifier [′äp·tə·kəl ′am·plə‚fī·ər] (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 fiber amplifiers enable optical signal transmission over very long distances without the expensive process of conversion to electronic signals, electronic amplification and the conversion back to optical signal again as in traditional regenerators. IPG's proprietary technology, materials science expertise and vertically integrated manufacturing operations enable IPG to produce the largest variety in the world of cost-effective, high and low power fiber amplifiers and lasers with substantial power efficiency, and improved noise performance, reliability and quality. |
