What happened to the home gateway fiber optic signal flashing red?

Reasons: 1. The optical fiber is broken (more likely), and the optical fiber pigtail is not inserted into the optical modem.

on (check it yourself).

2. Optical modem failure (small likelihood), uplink optical splitter failure (generally this kind of failure, the surrounding neighbors can't use it).

Solution: 1. Under normal circumstances, the light signal flashing red represents the light receiving power.

If it is too low, or if you can't receive light, it is recommended to check the line, or contact the service provider directly.

2. Explain that the optical path is not passable, that is, the optical fiber is broken, and you can only call the maintenance personnel to repair or rewire it if you are not plugged in or the bending angle of the optical fiber is too large.

If the LOS light of the optical modem turns red or flashes, it is usually caused by the following conditions:

If there is a problem with the optical interface of the optical modem, you need to replace the optical modem.

The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in;

The bend of the optical fiber in the indoor part 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;

If the outdoor optical fiber is broken or the optical port of the equipment in the equipment room is faulty, you need to contact the staff to report the fault.

The light signal flashes red light to solve the tutorial, know the cause of the problem, the solution is too simple!

If the LOS light on the optical modem turns red or flashes, it is generally faulty, as follows:

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

2. The indoor pigtail connection optical cat connector is loose, and the connector can be restored by plugging it in;

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. If the optical fiber of the outdoor part is broken or the optical port of the equipment in the computer room is faulty, it is necessary to report the broadband fault, and there will be staff to come to the door to troubleshoot the fault after the fault report.

The causes and solutions of the optical fiber turning on the red light are as follows:

1. The indoor pigtail connection optical cat connector is loose or the contact is poor, in this case, you need to dial down the interface and clean it up, and then plug it back in to try.

2. The bending of the indoor part of the optical fiber is too large, and the 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.

3. The optical fiber is broken, when the bending angle of the optical fiber is too large, the inside of the optical fiber has been broken, resulting in the optical signal can not be successfully transmitted in, contact the maintenance personnel to rewire.

4. If there is a problem with the optical interface of the optical modem, this situation is a hardware problem of the optical modem, if there is a problem with the optical modem interface, the optical signal will not be transmitted to the optical modem, contact the maintenance personnel to repair or replace it with a new optical modem.

5. Broadband arrears, now broadband services are basically postpaid mode, operators will close broadband services due to customer service arrears for too long, in this case, only need to pay off the arrears.

6. Regional broadband failure, it may be that the broadband in the entire region is being repaired or repaired, in this case, you can call customer service ** to understand the situation, and wait for the maintenance personnel to repair the broadband.

7. System problems, if the entire area has been shut down, it is a problem with the system, just wait patiently, or contact customer service to explain the situation. <>

If the optical signal light turns red or flashes, it means that the optical fiber signal cannot be received, which is usually caused by the following conditions:

If there is a problem with the optical interface of the optical modem, you need to replace the optical modem.

The indoor pigtail connection optical modem connector is loose, and the connector can be restored by plugging it in;

The bend of the optical fiber in the indoor part 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;

First of all, check whether there is a problem with the optical modem, use a screwdriver to unscrew the screws of the optical modem, open the optical modem, and take off the coupler and replace it with a new one.

1. Check whether the optical fiber interface plugged into the optical modem is loose. Restart the modem, turn off the power of the modem, and wait for a few minutes. 2. There is a problem with the optical interface of the optical modem, and the optical modem needs to be replaced.

3. Your broadband bill is in arrears. Nowadays, broadband is basically a postpaid model, because you have been in arrears for too long, and the operator directly turns off your broadband, and you need to pay off the arrears to recover.

There are several ways to do this.

Questions. Okay thank you.

The signal source is cut off, usually caused by a broken wire.

Fiber optic pigtails. The connection with the fiber coupler is disconnected, that is, the optical modem.

There is a problem with the optical fiber connection, and the optical signal flashes red, indicating that the optical fiber signal is abnormal.

Try to disconnect and reconnect, if you can't recover yourself, you can call customer service to arrange for a staff member to handle it for you.

1. Reason: The connection between the optical fiber pigtail and the optical fiber coupler is disconnected, that is, there is a problem with the optical modem and the optical fiber connection, although the staff is still checking the connection when installing, but after a long time of use or human factors will cause the coupler and the pigtail to be disconnected. Workaround:

Try to reconnect the pigtail, don't use too much force, it will easily cause the fiber to bend and break;

2. Reason: Because the materials that make up the optical fiber are glass and plastic, the optical fiber is very easy to be damaged and broken in the state of bending and extrusion. Workaround:

The general optical fiber damage and fracture is not able to see the obvious scars, and the user himself can not repair it, it is recommended to immediately call ** to find broadband maintenance personnel, optical fiber fracture repair is very convenient, and very cheap;

3. Reason: The probability of this kind of failure is still very small. Solution: Find a staff member to change to a light modem;

4. Reason: The remaining reason is probably the upper beam splitter.

Failures, which can cause problems with the local area network, where many users in an area are unable to connect to the network. Solution: Wait for a few minutes after power-off, and then restart the modem. This kind of failure will be fixed very quickly;
