Problems solved by technology

[0002] Optical fiber technology is widely used in the fields of communication, monitoring and control. However, due to the unrecognizability of optical communication, the intelligence in the field of optical fiber technology relies on the unique identification after converting optical signals into electrical signals. The wavelength is limited, and unique identification cannot be realized in a large area. For this reason, a method that not only realizes normal transmission of optical signals but also unique identification is needed

Abstract

The invention provides a system for realizing optical fiber coding by utilizing a circulator. The system comprises at least one optical circulator, an input / output end, another input / output end and fiber Bragg gratings. Optical fiber coding of the optical fiber medium part is realized by re-carving a plurality of fiber Bragg gratings of different wavelengths on circulator branches. With the adoption of the circulator structure, influence on optical cable communication is avoided, and the system is simple in structure, low in cost and excellent in application effect.
