With the rapid increase of data volume in today's era, higher requirements are put forward for data transmission technology, especially in terms of transmission speed, stability and reliability. When the traditional single channel LVDS data transmission system transmits for a long distance, its transmission rate is often only a few hundred Mbps, which is difficult to meet the requirements of high-speed data transmission. Therefore, this paper proposes a comprehensive optimization scheme: in terms of hardware, two groups of four channel LVDS chips are used as the high-speed interface of data, which realizes eight channel LVDS transmission and improves the data transmission rate; However, as the rate increases, the probability of error code generation under the effect of crosstalk and electromagnetic interference also increases. Therefore, it is necessary to cooperate with the anti-interference ability and long-distance transmission ability of LVDS dedicated data driver and cable equalizer system; In addition, RS encoding and decoding technology is introduced into the software logic to achieve error correction within a certain range. With automatic retransmission technology and CRC verification, the reliability of data transmission is improved. After many tests, the design can finally achieve 4000mb/s zero error transmission under 80m twisted pair shielded cable.
