As the core equipment of mining network communication, the performance of mining 10G switches directly affects the production efficiency and safety of the entire mining area. However, the mining environment is complex and there are a large number of electromagnetic interference sources, such as large motors, high-voltage wires, etc., which pose a severe challenge to the data transmission reliability of the switches.
