Optical modules are used in industrial automation to connect various industrial equipment, such as PLC, servo drive, etc., to achieve efficient communication and data exchange between equipment, which helps to improve production efficiency and management level. Optical modules can also be used to build industrial Ethernet and fieldbus networks to achieve real-time communication and collaborative work between equipment, and improve the automation and intelligence level of production lines. Because of its characteristics such as supporting long-distance transmission, anti-electromagnetic interference and radio frequency interference, optical modules can operate stably in complex industrial environments.

In precision manufacturing and processing industries, such as semiconductor manufacturing and precision instrument manufacturing, electromagnetic interference is very sensitive. Radio frequency interference may affect the accuracy and stability of equipment, so an environment without radio frequency interference is required to ensure product quality. Data networks based on optical modules can meet such requirements. In addition, there are often a large number of electrical equipment in industrial environments, such as motors, inverters, switches, etc., which will generate strong electromagnetic interference when running. The anti-electromagnetic interference characteristics of optical modules enable them to work stably in such an environment and ensure the reliability of communication.
