Abstract:

In order to achieve high-bandwidth real-time Cameralink-Full mode digital image for the purpose of long-distance transmission, the Cameralink digital image optical fiber transmission system based GTX serial transceiver is provided for the shortcomings of current systems. Increase the transmission bandwidth and the suitability of the digital image optical fiber transmission system by using GTX serial transceiver replace encoding and decoding chip to realize the serial data conversion function, time division multiplexing of channels and asynchronous FIFO. Experimental results show that, GTX serial transceivers data error rate of 10-12 or less, the transmission bandwidth of the optical fiber transmission system reach 4.19 Gb/s.
