What is the reason why the light signal turns red?

The reasons why the optical signal lights up in red are: 1. The optical fiber is broken; 2. The optical fiber pigtail is not inserted into the optical cat; 3. The optical cat is faulty; 4. The uplink optical splitter is faulty. The solution: 1. Check whether the fiber optic cable behind the fiber optic modem is folded or squeezed; 2. Refresh or restart the broadband port; 3. Ask staff to come to repair.

Such a phenomenon indicates that the computer cannot access the Internet normally. At this time, you should check the following details to restore the network failure:

1, fiber optic Broken (highly likely)

2. The optical fiber pigtail is not inserted into the optical modem (check it yourself)

3. The optical modem is faulty (low possibility)

4. The uplink optical splitter is faulty (usually this kind of fault will not work for your neighbors.)

The light signal on the fiber optic cat displays a red light, indicating that there is a problem with the fiber. As a result, the network slows down or the Internet cannot be accessed at all.

Solution:

1. Check whether the fiber optic cable (usually a yellow soft cable) behind the fiber optic cat is folded or squeezed. Use a little force to straighten the cable and look at the red light. Whether the situation has returned to normal.

2. Call the broadband customer service number and ask customer service to help refresh/restart the broadband port. Turn off the power of the fiber optic modem and router, wait 5-10 minutes and restart to see if the situation is restored.

3. If 2 cannot be restored, call the broadband customer service number to inquire whether there is a large-scale failure or power outage in the current area where the customer service is located, and inform the customer service that the broadband used is unavailable and should be reported for repair. Wait for the staff to come to repair.

The optical fiber is the leather jumper with the blue head in the middle of the optical cat. It cannot be beaten to death, and if you have pets, it will be easily bitten by puppies.
