Abstract

The invention provides a multi-core few-mode sensing communication converged access transmission system. The multi-core few-mode sensing communication converged access transmission system is based onthe unique advantages of optical fiber distributed sensing, integrates the advantages of high speed, large capacity, long-distance transmission and the like of optical fiber communication, utilizes amulti-core few-mode optical fiber, combines an optical fiber space division multiplexing technology, and realizes fusion of optical fiber sensing and communication through reasonable design and distribution of fiber cores and modes; and the multi-core few-mode sensing communication converged access transmission system further applies the technology to monitoring and transmission of environmental information, can realize real-time sensing of multiple parameters (temperature, bending, strain and the like) of a complex environment, is conductive to mastering the influence of external factors on the communication condition in real time, analyzes the reason why a communication signal changes in the transmission process in time, and can provide help for stable signal transmission.

Description

technical field [0001] The invention belongs to the technical field of communication and sensing, and in particular relates to a sensor communication fusion access transmission system with multiple cores and few modes. Background technique [0002] In 1966, the British-Chinese physicist Gao Kun proposed to make optical fibers with quartz materials. In 1970, Corning Corporation of the United States produced the first low-loss optical fiber. Since then, technologies with cross-age significance such as optical fiber communication and optical fiber sensor devices have been continuously developed on this basis. Optical fiber sensing technology was born in the late 1970s. Like traditional sensing technology, fiber optic sensing technology is also used to perceive external signals. Its special feature is that optical fiber integrates external signal perception and information transmission. According to different measurement methods, optical fiber sensing technology can be divid...
