Why does the optical transceiver have no signal?

Why is there no signal phenomenon in the optical transceiver? What is the cause of this is the main content that the Pacific Security Network Xiaobian wants to introduce to you. It is no stranger to mention the optical transceiver, especially in the security field. In recent years, with the continuous development and updating of optical transceiver technology, it is now successfully applied in various fields. However, when we use optical transceivers, there will always be no signal phenomenon. What causes the optical transceiver to have no signal phenomenon? What? Here is a small series for you to solve problems,

When we use the optical transceiver, in the case of no signal, we have to check it:

Check whether each device is powered normally.

Check whether the video indicator of the corresponding channel on the receiving end is lit. If the indicator is on, it indicates that the channel has a video signal output. At this time we have to check cable receiving end video monitor or the like between the terminal device is connected DVR, whether video interface loose connections or soldered etc.

If the video indicator on the receiving end is not lit, check whether the video indicator of the corresponding channel on the front end is lit. It is recommended that you re-power the optical receiver to ensure the synchronization of the video signal.

If the above aspects can not eliminate the fault, this is the method we can use the replacement check, mainly using the same type of equipment for the interchange test, that is, the fiber is connected to the receiver at the other end or the remote transmitter is replaced. The faulty device can be accurately judged.
