1. Check if the OPT indicator on the transmitter or receiver is lit. If it does not light, please follow section 2 below. If it is on, please check according to steps 3~4.
2. Check whether the end of the optical fiber jumper that is connected to the optical transceiver is dirty. If there is any dirt, wipe it with clean alcohol and then try again; Check whether the optical fiber jumper is broken or excessively bent; if possible, use an optical power meter to check The optical output power (DB value) of the transmitter checks the optical power of the transmitter after being attenuated by the optical cable at the receiving end. If the absolute value of the difference between the two values ​​exceeds 18 dB, it can be judged that the attenuation of the optical cable link is too large, and it may be the optical cable. If the cable is not long enough or the cable length exceeds the device's transmission distance, please contact us.
3, check whether the installation of equipment is the opposite, the transmitter and receiver can not be used in reverse. The transmitter should be connected to the camera.

4. Check if the video input indicator of the transmitter is always on. If it is not on, there is no video output from the camera. Check whether the camera is normal and whether the video cable is connected to the BNC interface of the optical transceiver. If the video indicator of the transmitter is on, you should check the video input indicator. Check the receiver. If the corresponding video indicator is on, check whether the video cable is connected to the optical transceiver and monitor.
