If the optical fiber is on, there is no signal or any reason for it

Dear, there is no optical signal in the broadband, which may be caused by the following situations, and the optical modem needs to be replaced. 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.

This is usually due to the presence of several 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.

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;

2. Regional broadband failure.

3. Broadband arrears.

At present, broadband services are basically postpaid, and operators will shut down broadband services due to customers who have been in arrears for a long time.

4. Abnormal indoor pigtail.

If the connector is loose or the contact is poor, you need to remove the connector and clean it up and plug it back in.

5. There is a problem with the optical interface of the optical modem.

In this case, the only way to do this is to send the modem to customer service for repair or replace it with a new one.

This is because the optical modem failed to receive the signal from the optical fiber.

If it still persists, you can report to the carrier's customer service for repair.

There are several causes and solutions:

1. Broadband arrears: Broadband is basically postpaid, and operators will shut down broadband services because customers are in arrears, in which case they only need to pay off the arrears.

Second, there is a problem with the broadband interface of the router, and the crystal plug of the interface is loose or the contact is poor, which will also cause this to happen, and the crystal interface needs to be dialed out and cleaned up before being reinserted into the broadband interface.

Sometimes the router will have an internal program error, so you need to turn off the router for 5 minutes before restarting it.

5. Regional network maintenance or repair, it may be that the network in a region is broken, and the maintenance personnel are repairing, you can call the telecom customer service to understand the situation and wait for the maintenance personnel to repair it.

Sixth, the upward beam splitter is auspicious and calls for wide barriers. If the uplink splitter fails, generally your neighbor's router will also have the same symptoms as you, in this case, only the warranty waiting for the staff to chain the door for repair.

If the optical signal on the fiber modem is not bright, there is no signal. Workaround:

1. First of all, a device must have a power supply, so the power supply light must be long, and then the network is a signal light for telecommunications, if it is always on, the electrical signal is normal, and a flash or a flash of light signal flashing red indicates that the signal is abnormal.

2. The light signal indicates that the light is to the optical fiber head.

When the sub is broken, as long as you look at it flashing red, the optical fiber must be broken.

4. If the home is also installed, the voice light will be on.

5. Network 1 refers to the optical modem.

It will only light up when the computer connection line is normal.

6. At present, the default network port 1 has data, and the network port 2 has no data deficit and cannot access the Internet.

It is usually caused by the presence of the following old species:

There is a problem with the optical interface of the shirt vertical optical modem, and the optical modem needs to be replaced;

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 failed, or the optical port of the equipment in the equipment room is faulty, you need to contact the staff to report the fault.

If the optical signal on the fiber modem is not bright, there is no signal. Workaround:

1. First of all, a device must have a power source, so the power lamp must be long, and then the network is the signal light of the telecommunication, and if it is long, it means that the signal is normal, and if it flashes or the signal flashes red, it means that the signal is not normal.

2. The optical signal indicator light is used for the optical fiber head when it is broken, and the optical fiber must be broken if you look at it vertically when it flashes red.

3. Broadband is a flashing of data on the line after connecting to the Internet.

4 , if the home is also installed , the voice light will be on .

5. Network 1 refers to the light cat to the computer connection circuit that is usually bright.

6 . At present it is tacitly recognized that network port 1 has data, but network port 2 does not have data and cannot be connected to the network .

Hello, the wired network does not have a fiber optic signal is not necessarily a fiber optic cable interruption, it must be tested to accurately judge the fault point, and then according to the scope of the fault point to troubleshoot, the test method is as follows:

1. Set up the dial-up connection according to the requirements of the operator, connect the stand-alone device to the operator's optical modem, and ping the operator's gateway or DNS server address after dial-up the Internet;

2. If the ping is not working, it means that the operator's external network network is not connected, just call ** to find the operator to report for repair;

3. If the ping means that the external network network is normal, it has nothing to do with the operator's network, and the fault is on the router, restore the router to factory settings, and then reset it to eliminate the fault.

4. If the router still fails after step 3 above, you can judge that the router hardware is faulty and you can only replace the router.

Difference Between Fiber Optic and Wired Broadband:

1. Optical fiber broadband is also wired access.

2. It is different from optical fiber line and ordinary copper wire, and the transmission medium is different.

3. Optical fiber uses optical transmission, which is faster.

4. The copper wire adopts weak current signal transmission, which is slow to transmit and consumes a lot.

5. The following is the difference between optical fiber cable and ordinary network cable.

1. Please confirm whether the broadband Internet access is normal, if you can't access the Internet, please follow the broadband fault handling process; If the Internet access is normal, go to Step 2.

2: Restart the modem and set-top box, and if the fault persists, go to step 3.

3. Check whether the network cable between the modem and the set-top box is normal, you can check whether the lights connected to the interface of the set-top box and the modem are green (normal when the green light is on), if the red light is on, try to plug in the network cable or replace other ports on the modem, if possible, replace a good network cable, and restart the set-top box to see if the fault disappears. If the fault persists, go to Step 4.

4. Please check the network connection mode of broadband and ITV, if you use a router or modem or switch with routing function, please remove the router first, disconnect the computer, connect a single set-top box directly to the modem, and restart the set-top box to see if the fault still exists. If the fault persists, please call Anhui Telecom customer service**10000+4+1 for consultation.
