Yukuan optical transceiver is a kind of signal conversion equipment, which mainly converts traditional TV signals into optical signals so that they can be transmitted on optical fibers, and can make the transmission distance longer and the transmission rate greater, and the stability is good. Some minor faults will inevitably occur during use, which is normal.

1. No video signal

If there is no video signal during use, first check whether the power supply of the device is normal. Secondly, check the channel video indicator corresponding to the receiving end of the optical transceiver to see if it can light up normally. If the indicator light can light up normally, it means If the channel has a video signal output, check whether the video cable between the receiving end and the monitor or terminal equipment such as DVR is well connected, and whether the video interface connection is loose or there is false welding. In addition, if the video indicator on the receiving end of the optical transceiver is not on, check whether the video indicator on the corresponding channel at the front end is on.

2. Interfering snowflakes appear on the screen

There are interference snowflakes on the screen, which may be caused by excessive attenuation of the optical fiber link, or the front-end video cable is too long due to AC electromagnetic interference. At this point, you should first check whether the pigtail of the optical transceiver is excessively bent. In addition, check whether the connection between the optical port of the TV station's optical transceiver and the flange of the terminal box is reliable, and whether the flange core is damaged or not. In addition, check whether the optical port and pigtail are too dirty, if so, clean them with alcohol and cotton and wait for them to dry before inserting them.

Under normal circumstances, Yukuan optical transceivers are not prone to malfunctions, and abnormalities may also occur if they are improperly operated during use or because of carelessness. Therefore, you must be cautious when using the optical transceiver. If a fault occurs accidentally, you must follow the above introduction to troubleshoot and solve the fault.
