Optical fiber transmission control method and system

Abstract

The invention relates to an optical fiber transmission control method and a system, which belong to the technical field of optical fiber transmission and are used for solving the problem that RS232, I2C and other universal low-speed bus interfaces in the existing IEEE1394b protocol application technology are incompatible. The optical fiber transmission control method comprises the steps of completing caching and transmission of IEEE 1394b asynchronous data, RS232 data and I2C data for completing configuration of protocol conversion, completing the protocol conversion of IEEE 1394b protocol electrical signals according to the configuration, converting the input IEEE 1394b protocol electrical signals to electrical signals for output through photoelectric and electro-optic conversion and converting the input IEEE 1394b protocol electrical signals to optical signals for output. The control method and the system realize the mutual compatibility of RS232 and I2C universal interface equipment with an IEEE 1394b bus through mutual conversion between IEEE 1394b protocol signals and RS232 and I2C protocol signals and command parsing, thereby improving the scalability of the IEEE 1394b protocol.

Description

technical field [0001] The invention relates to an optical fiber transmission control method and system, belonging to the technical field of optical fiber transmission. Background technique [0002] With the strengthening of informatization, the structure of electronic information equipment and electronic systems is becoming more and more complex, the amount of transmitted data is increasing, and the structure of transmitted information has also changed, from the original command and status to the current inclusion A large amount of audio, video and image data transmission. With the rapid increase in the amount of transmitted data, the requirements for real-time analysis and processing capabilities and information fusion capabilities of transmitted data are also increasing. However, the traditional point-to-point cable transmission method has a transmission bandwidth of less than 200Mbps, a delay of about 5s, and a transmission distance of less than 10m. The data is suscept...
