Optical modules are mainly used in security monitoring systems to achieve real-time transmission of high-definition video data, ensuring the clarity and smoothness of the monitoring images. Since security monitoring systems have extremely high requirements for the stability and real-time performance of data transmission, optical modules have become an indispensable key device in the security field with their stability and low latency. In addition, because optical modules support long-distance transmission, security monitoring systems can cover a wider area and improve monitoring efficiency.
