近年来,随着平安城市等大型视频监控系统向网络化、高清化、集成化发展,传输系统也在市场需求的推动下开始了技术升级,作为其中的一个重要组成部分,光端机的应用及发展也一直为业内所关注。在视频监控系统中,监控图像的传输是整个系统的一个至关重要的环节,选择何种介质和设备传送图像和其它控制信号将直接关系到监控系统的质量和可靠性,传输部分是整个监控系统的中枢神
In recent years, as large-scale video surveillance systems such as Ping An City have developed into networks, high-definition and integrated systems, transmission systems have started to upgrade their technologies under the impetus of market demand. As an important part of the system, the application and development of optical transceivers Has also been the industry’s attention. In the video surveillance system, the monitoring image transmission is a crucial part of the whole system. Choosing which medium and equipment to transmit images and other control signals will directly affect the quality and reliability of the monitoring system. The transmission part is the whole monitoring System of the central god
