Abstract: This article introduces an industrial network isolation technology based on the photo data transfer principle. By utilizing a non-networked data transmission system, it effectively blocks and isolates existing and future network-based viruses and hacker attacks. After decades of research and development, this technology has evolved into multiple product lines and dozens of products, which have been deployed in large-scale industrial networks for a long time, demonstrating stable and reliable operation. During the recent "WannaCry" virus attack, this technology successfully blocked the attack, maintaining the DCS and production equipment within the isolated protection zone intact.
