Abstract

An FPGA-based optical fiber to fully configured Camera link real-time image optical transceiver, which realizes the conversion function of optical fiber real-time image input to high-bandwidth (85MHz) and high-reliability full-configuration (Full) Camera link real-time image output, and has Full configuration (Full), medium (Medium) or basic (Base) Camera link self-adaptive configuration function of real-time image output, self-adaptive function of Camera link output working frequency, and realizes serial port data and timing synchronization control of Camera link The conversion function of signal input to optical fiber data stream output extends the communication distance of the serial port and timing control signal of Camera link; the design provides flexible configuration of SFP optical fiber module, and the transmission distance is from 500 meters to 120 kilometers, which improves the real-time performance of Camera link The stability and reliability of image transmission enhances the anti-electromagnetic interference capability of Camera link real-time image transmission and meets the needs of various engineering applications.

Description

technical field [0001] The present invention relates to high-bandwidth (85MHz), high-reliability full-configuration (Full) Camera link real-time image long-distance transmission, in particular to a Camera link high-speed real-time image remote transmission based on FPGA (Field Programmable Gate Array, Field Programmable Gate Array) Distance transmission is realized. Background technique [0002] In the traditional Camera link image transmission system, the transmission medium between devices is directly connected by Cameralink cable. Due to the poor anti-interference performance of the Camera link cable and the short transmission distance (less than 10 meters), it cannot meet the long-distance requirements. distance transmission.

[0002] In the traditional Camera link image transmission system, the transmission medium between devices is directly connected by Cameralink cable. Due to the poor anti-interference performance of the Camera link cable and the short transmission distance (less than 10 meters), it cannot meet the long-distance requirements. distance transmission

In recent years, with the development of optical fiber interconnection transmission technology, basic (Base) Camera link image optical transceivers based on optical fiber transmission have gradually appeared, but they can only realize basic (Base) Camera link image transmission, and the transmission distance is short (about 300 meters), which fail to meet the long-distance transmission of long-distance camera link real-time images with medium configuration (Medium), full configuration (Full), and high bandwidth (85MHz) for engineering needs, and fail to meet the transmission of longer distances (100 kilometers and above) need
