Problems solved by technology
[0004] However, when a single amplified light source is used for Raman amplification, a new nonlinear effect (Brillouin effect) will be generated when the amplified light of the same wavelength is transmitted in the fiber at a higher power, resulting in the obtained Raman effect The energy is reduced, resulting in a weakened light amplification effect

The invention discloses an optical distributed amplification structure, and belongs to the technical field of optical amplification. The optical distributed amplification structure comprises an amplification light source module, a coupling and reflecting module, a front-end reflecting module and a rear-end reflecting module. According to the structure provided by the invention, the mixed light of the first amplified light and the second amplified light is emitted through the amplification light source module, the first mixed light is sent to the first light path through the coupling and reflecting module, and the second mixed light is sent to the second light path, so that the amplified light in the first mixed light meets the original signal light transmitted by the first light path; the amplified light in the second mixed light meets with the signal light transmitted by the second light path and subjected to primary amplification processing so as to transfer the optical power, the structure utilizes the two kinds of amplified light to amplify the signal light at the same time and also carries out secondary amplification on the signal light, so that the amplification effect can be enhanced, the two kinds of amplified light with different wavelengths are adopted, and the light conversion efficiency is improved. The Brillouin effect can be prevented from being generated in the transmission process, and the amplification effect is prevented from being weakened.
Description
technical field [0001] The present application relates to the technical field of optical amplification, and in particular, to an optical distributed amplification structure. Background technique [0002] With the development of the national economy, the role of optical fiber communication in production and life is becoming more and more important, and as people's demand for communication network capacity continues to increase, in order to meet people's demand for communication network capacity, optical amplifiers are usually used to enhance optical communication. capacity. [0003] At present, optical amplifiers usually use Raman amplifiers. Raman amplifiers mainly perform optical amplification based on nonlinear effects (Raman effects) in optics. Specifically, Raman amplifiers perform optical amplification on the light to be amplified transmitted in the optical fiber. When the single amplified light is input into the fiber with a certain power, the single amplified light a...
