Fiber Optic Transmission Advantages of Monitoring Engineering
The best way to solve the long-distance transmission is to use optical fiber to transmit image signals in the monitoring project. The optical fiber transmission can reach tens or even more than 100 kilometers. It transmits video and control signals to optical signals and transmits them in the optical fiber. Its advantages are: long transmission distance, high speed, large bandwidth, small attenuation, and anti-interference. The best performance, suitable for long-distance and large-scale video transmission, such as road intersection monitoring.
Optical fiber transmission equipment is mainly video optical transceivers and optical fiber transceivers. Video optical transceivers are mainly used for signal transmission of analog cameras. It has low signal loss, low noise and distortion, high transmission quality, and is suitable for long-distance transmission. At present, the monitoring optical transceiver can transmit signals such as images, data and voice without relay for 100 kilometers. Secondly, it has strong anti-interference ability. It is not affected by lightning and electromagnetic radiation. This is not available for coaxial cable transmission and twisted pair transmission. of.
The transmission frequency bandwidth of the monitoring project can reach 3 billion megahertz in theory, and the communication capacity is large, which is very suitable for video signal transmission. A video optical transceiver can simultaneously access multiple groups of analog video signals, which is suitable for multiplexed transmission. At present, the monitoring optical transceiver can realize simultaneous transmission of 128 real-time uncompressed broadcast-level images on a core fiber, and the video optical transceiver can not only transmit video Signal, while also transmitting audio signals.
The optical fiber transceiver of the monitoring project is suitable for the signal transmission of the network camera. It also has the advantages of long transmission distance, small loss, and strong anti-interference ability of the video optical transceiver.
