What's with the light cat flashing red all the time?

The light cat's red light flashes all the time, usually the light signal light flashes, indicating that the light port of the light cat can't receive the light signal, which leads to the user's inability to surf the Internet normally. The reasons why the light cat can't receive the light signal and the solutions are as follows:

The optical cat connector connecting the optical fiber in the user's room is loose, that is, the optical fiber cable is in poor contact with the optical cat interface, so the user only needs to plug it in again and check whether the optical signal lamp is back to normal again.

Some optical fibers in the user's room are bent too much, which will affect the total reflection transmission of optical signals in the optical fiber. Check whether the optical fiber line behind the optical fiber cat is folded or squeezed, straighten the optical fiber line, and then see if the light cat signal lamp returns to normal.

There is something wrong with the light cat itself. If the user uses the optical cat for a long time, it is also possible that the optical receiver is partially damaged, which will also cause this phenomenon. In this case, the network operator can only be informed to arrange personnel to come to the door for replacement.

The luminous rate of the optical port of the equipment in the computer room set up locally by the network operator is low or not luminous. It is also possible that the local optical cable failure, optical splitter error or even local power failure may cause the red light of the light cat signal lamp at the user's client to flash and give an alarm. In this case, users can't solve it by themselves, so they need to contact the network operator to arrange personnel to solve it at home.

Expanding data knowledge: Optical Cat is actually equivalent to a crude version of optical fiber transceiver, which is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pair electrical signals with long-distance optical signals, and is also called optical fiber converter in many places. Products are generally used in the actual network environment where Ethernet cables cannot cover and optical fibers must be used to extend the transmission distance, and are usually located in the access layer of broadband metropolitan area networks. Such as: monitoring the transmission of high-definition video images in security engineering; At the same time, it also plays a great role in helping to connect the last mile optical fiber line to metropolitan area network and external network.
