Abstract

The invention provides a data self-healing ring network organizing system based on optical fiber transmission. The data self-healing ring network organizing system comprises one set of main site equipment and multiple sets of far-end site optical access equipment. The main site equipment and any one far-end site optical access equipment are respectively provided with two optical ports. A ring network link transmitting compressed video business data or other ethernet business data is formed by the main site equipment and the multiple sets of main site equipment. When an open circuit fault occurs in optical fibers, the main site equipment and the multiple sets of main site equipment can communicate continuously. Meanwhile, a time division multiplexing technology is adopted and the ethernet data of the multiple sets of far-end site optical access equipment are transmitted by the same optical fiber so that a transmission line is simplified, transmission capacity is enhanced, automatic allocation of time slots is realized by the main site equipment, normal working of the multiple sets of far-end site optical access equipment and the main site equipment is coordinated and a technical problem of relatively low efficiency in high-load transmission is solved.

Description

Technical field: [0001] The invention relates to the field of physics, in particular to optical fiber transmission technology, in particular to a data self-healing ring network networking system based on optical fiber transmission. Background technique: [0002] With the development of network intelligent systems and multimedia systems, the video data transmission system in the video surveillance business needs to solve the problem of long-distance transmission of video sources, and at the same time, the problem of video data networking is also required. In the prior art, using optical fiber as the transmission medium is a common method to solve the problem of long-distance transmission of video sources, but the number of transmission video channels is very limited when the total bandwidth is the same for optical fiber transmission of uncompressed video data. For example, an Ethernet switch with an optical fiber interface is used for transmission in a tree or star network. ...
