Optical transceiver use and application
An optical transceiver is an Ethernet media transmission device that not only transmits video signals, but also transmits audio, telephone, network, and a variety of control signals. Currently mainly used in the security monitoring industry. Let's take a look at the application of optical transceivers!
Our video surveillance connection during short distances
We use the video cable, which is the daisy line we usually say, to connect the monitoring and display devices (as shown in Figure 1), but when the distance exceeds a certain distance, the transmitted analog signal will increase with distance. Big, the signal is also weakened. Eventually, the video on the monitoring side will be blurred, and the picture will be intermittent and will not reach the monitoring effect. In this case, the optical transceiver will come into being.

Our video surveillance connection at a great distance
At relatively long distances, our video surveillance connection will be applied to our optical transceivers. It is well known that optical transceivers are used in pairs, one end is the transmitting end (A), and the other end is the receiving end (B); the application is also very simple, which is to use the optical transceiver to transmit signals in the middle based on the short-distance monitoring connection. This increases the distance of transmission and achieves the monitoring effect we want.
To be more detailed, the surveillance camera is connected to the PNC interface of the transmitting end (A) of the optical transceiver, and the analog signal is converted into an optical signal, which is transmitted to the receiving end (B) through the optical fiber cable, and then the receiving end (B) of the optical transceiver will be The optical signal is converted into an electrical signal and transmitted to the monitoring terminal, so that the effect of remotely monitoring the clear video can be achieved! (As shown in FIG. 2)
