As the distance increases, the optical fiber communication signal will continue to weaken, which is an unavoidable and important problem in the transmission of communication signals, and also the main problem that needs to be solved in the transmission of long-distance signals.

At present, in the treatment of related problems, signal amplifiers are mainly used to enhance light wave signals, which can offset the signal attenuation during signal transmission to a certain extent, but cannot fundamentally solve the problem of signal attenuation.

The weakening of the communication signal is directly related to the communication medium material, communication environment, communication technology, etc.

Taking silica fiber as an example, although it has good performance, the silica fiber material will contain different contents of impurity materials, and the proportion of these impurity materials will directly affect the communication transmission performance of the silica material and affect the loss of light wave energy consumption. .

In addition, if the optical fiber material is deformed to varying degrees during use, it will cause the loss of light wave energy consumption and affect the stability of the communication signal; improper handling of the connection of the optical fiber material will also lead to the attenuation of the communication signal.

In order to solve the problem of weakening communication signals, it is necessary to apply communication signal regeneration technology to ensure the normal transmission of communication signals and avoid further expansion of signal transmission accidents. The communication signal regeneration technology is mainly used to make up for the weakening of the communication signal, so as to reduce the actual operation and use cost of the communication network system.
