Application of Amplifying Technologies to Increase
Optical Signal Power
Abstract
In modern times, due to the rapid development of information and communication technologies, the demand for broadband and high-speed data transmission systems is constantly increasing. One of the most reliable and effective solutions to meet these needs is the application of optical fiber communication systems. Signal transmission via optical fibers is considered one of the most modern technologies in terms of high bandwidth, low attenuation and resistance to electromagnetic influences.
However, as the distance increases, optical signals weaken, which limits the quality and range of transmission. In order to prevent such signal weakening and maintain quality during long-distance transmission, various optical amplification technologies are applied. These technologies allow the signal to be amplified directly in optical form without converting it into electrical form, thereby increasing the overall efficiency of the system.
The main purpose of this article is to examine the types of amplification technologies used to increase the power of an optical signal, their working principle and application areas. In particular, the advantages and limitations of advanced technologies such as EDFA (Erbium Doped Fiber Amplifier), RAMAN amplifiers, and SOA (Semiconductor Optical Amplifier) will be analyzed.
