How to choose transmission equipment in the security monitoring industry is a very important link. Optical cable manufacturers will focus on the characteristics and advantages of optical fibers in monitoring and security.

Using optical fiber to transmit image signals in optical fiber fusion is the best way to solve long-distance transmission. Optical fiber transmission can reach tens or even more than 100 kilometers. It converts video and control signals into optical signals and transmits them in optical fibers. Its advantages are: long transmission distance, high speed, large bandwidth, low attenuation, and anti-interference. The performance is the best, suitable for long-distance and large-scale video transmission, such as road intersection monitoring and so on. The equipment using optical fiber transmission is mainly video optical transceiver and optical fiber transceiver. Video optical transceiver is mainly used in the signal transmission of analog cameras. It has small signal loss, low noise and distortion, high transmission quality, and is suitable for long-distance transmission.

At present, the monitoring optical transceiver can transmit images, data and voice signals for 100 kilometers without relay.

Strong anti-interference ability, it is not affected by lightning strike and electromagnetic radiation, which is not available in coaxial cable transmission and twisted pair transmission. Transmission frequency bandwidth, theoretically up to 3 billion megahertz, large communication capacity, very suitable for video signal transmission. A video optical transceiver can access multiple groups of analog video signals at the same time, which is suitable for multiplexing transmission. At present, the monitoring optical transceiver can simultaneously transmit 128 real-time uncompressed broadcast-level images on one core fiber, and the video optical transceiver can not only transmit video signal, and can also transmit audio signals. The optical fiber transceiver is suitable for the signal transmission of the network camera, and it also has the advantages of long transmission distance, low loss and strong anti-interference ability of the video optical transceiver.
