What is the problem with the red traffic light?

Generally, individual users will have several signal lights when using optical modems, and different signal lights flashing red will have different problems. light, this is the power light, bright green is normal, off is power failure, bright red is abnormal power supply or abnormal power supply of equipment. Flashing indicates that the connection with the parent device is being established, and off or red indicates that the superior device cannot be connected.

Lamp. This is a light signal light, this light only flashes, a long bright no light signal or the light signal loss is too large to indicate and extinguish the normal prompt, generally red light. Lamp.

A solid light indicates that a switch is connected, but no data is being transmitted. Flashing indicates that there is data transmission, turning off or red indicates that the switch has not been connected. This is the user port light, which is solid to indicate that the user device is connected but there is no data transmission.

Flashing indicates that the user's device is connected and there is data transfer. Off indicates that the user device cannot be connected. Red indicates that the operation is at an abnormal adaptive rate (for example, a forced 10 megabit rate).

The reasons may be these: optical fiber break (more likely), optical fiber pigtail is not inserted into the optical modem (check it yourself), optical modem failure (less likely), uplink splitter failure (generally this kind of failure, your neighbors around you can't use it.) You first check whether the home fiber is in good contact with the ONU, and then see if there is a dead bend or a heavy object pressing the fiber.

If it's all right, you can call 10,000 to report the problem.

The optical signal flashes red, indicating that the fiber-optic modem cannot receive the signal.

1. There is a problem with the optical interface of the optical modem, and the optical modem needs to be replaced. (This is rare).

2. The indoor pigtail connection optical cat connector is loose. Plug the connector in and it can be restored.

3. The bending of the indoor part of the optical fiber is too large. Excessive bending of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, as long as the optical fiber is straightened.

4. The outdoor part of the optical fiber is broken, and you need to find the operator to deal with it.

5. If the optical port of the operator's equipment room fails, the operator also needs to deal with it.

The network light signal flashing red light has the following possibilities:

1. If the red light keeps flashing, it may be a light cat.

There is a problem with the optical interface.

Explanation or decision: We should replace the light cat.

2. It may be that the connector connecting the pigtail indoors to the optical cat is loose.

Solution: We just need to check it and reconnect the connector.

3. It may be that the bending of the optical fiber in the indoor part is a bit large.

4. If the inspection result is that the outdoor part of the optical fiber is broken or broken, or because the optical port of the equipment in the computer room is faulty.

Solution: We can contact the staff to deal with it.

The optical signal keeps flashing red, indicating that the fiber signal transmission is interrupted, which is generally caused by the following conditions:

1. Your broadband payment is in arrears. Nowadays, broadband is basically a postpaid model, because you are in arrears for too long, and the operator directly shuts down your broadband, in which case you need to pay off the arrears to recover.

Second, the optical fiber in your area is under maintenance or has a rotten obstacle. Because there are many urban construction projects in China now, the optical fiber may be cut and the operator is rushing to repair it, in this case, you have to wait for the operator to repair the faulty fiber of the uplink splitter.

3. There is a problem with the router's optical signal interface. It may be that the interface is loose, or the interface is not in good contact, in this case, you need to remove the crystal interface of the optical signal and clean it up and plug it back in.

Fourth, the router is broken. This happens very rarely, because when the router is broken, it will not only flash the light signal red, you can try restarting the router a bit.

Fifth, the pin is the failure of the upward beam splitter. In general, in this case, the neighbors around you can't get on the network, and this can only be repaired to the operator and wait for the staff to come to the door for repair.
