Optical transceivers are divided into analog optical transceivers and digital optical transceivers. The so-called optical transceiver refers to converting an analog signal or a digital signal into an optical signal through an optical fiber. Optical transceivers are generally used in pairs. That is, optical transmitters, optical receivers. To give a simple example: the connection is: camera - optical transmitter - fiber - optical transceiver - receiving equipment.
Wireless bridges, instead of cables, use digital microwave transmission. Its connection method is: digital camera - wireless bridge - wireless bridge - receiving equipment. In short, wireless bridges are equivalent to network cables. Play a role in transmission.
Then, if we say that the entire monitoring system has been established through optical fiber, we want to transfer the monitoring image to another place. In the event that the line cannot be used, if it is an open environment, an appropriate wireless bridge may be selected for transmission based on the distance. Of course, because of the wired surveillance system, the camera may be analog or digital. Divided into two kinds of situations, if it is a video camera with an analog optical transceiver, then you can first convert the analog signal into a digital signal using an encoder, connect it to a wireless bridge, and use the decoder to restore the signal to an analog signal at the receiver. . If it is a digital camera, then the signal from the optical transceiver can be connected to the switch and directly connected to the wireless bridge through the switch. The method of implementation is also very simple.
