What s going on with the LOS light on the light drill turning red

There are several situations in which the light signal of the modem lights up red:

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. If the outdoor optical fiber is broken or the optical port of the operator's equipment room is faulty, you need to find the operator to deal with it.

What's going on with the mobile broadband cat los flashing red light, have you learned.

Hello, first, the light signal light flashing mainly includes the following aspects: 1. The light port of the computer room is not lit or not on, resulting in the light on the user side can not work normally. In this case, the optical signal lamp cannot receive the optical signal sent by the optical cable or the optical signal power is too low, which will cause the optical modem to shake hands with the computer room abnormally.

At this time, the signal light flashes or the red light alarms. 2. The failure of the lamp itself and the local damage of the collector will also cause this phenomenon. No matter which of the above three situations occurs, users basically can't solve it, and can only play ** anti-filial piety fighting failure.

2. Solution: 1. Check whether the optical cable behind the optical fiber cat (usually a yellow wire) is folded and squeezed, straighten the line with a little force, and see if the red light returns to normal. 2. Call broadband customer service**, and ask customer service to refresh and restart the broadband port. [o

Summary. Dear, I'm honored to have your question The information that the teacher found out for you here is: What is the LOS light flashing red light?

What is the LOS light and red light flashing optical fiber head: 1. The optical port of the computer room emits low or no light, causing the user's optical modem to work abnormally, at this time, the optical signal light cannot receive the optical signal sent from the optical cable or the power of the optical signal is too low, which will cause the optical modem to shake hands with the computer room abnormally, and the optical signal light will flash or alarm with a red light.

2. Optical cable failure (including broken optical splitter) will also cause the optical modem to not receive light or the light collection is too low, and the optical signal light will also flash or alarm with red light.

3. The failure of the optical modem itself and the partial damage of the receiver will also cause this phenomenon.

Now that the epidemic is repeated, you must pay attention to safety when you go out, <> go out, wear a mask, wash your hands frequently! Have a great day, <>

Hello, the flashing red light should be the optical modem not the router, the specific reasons are as follows:

1.Fiber outage (more likely).

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

3.The optical modem is faulty (unlikely).

4.Faulty uplink splitter (generally this kind of fault, your neighbors around you can't use it.) ）<

As long as you are sure that the pigtail fuel carrying width behind the light cat has been connected correctly, you can only report for repair and let the master come to overhaul it.

Solution: LOS is generally a red light, if it flashes, it means that your optical router cannot receive the optical signal (normally it should not be lit), at this time, it is recommended as follows:

1. Unplug the optical fiber head, clean the optical fiber surface with a cotton ball, and then return the optical fiber.

2. It is recommended to unplug the optical fiber plug on the cat, clean the lower joint with cotton dipped in alcohol, if there is no alcohol cotton, Pi Liang can find a cigarette, and the fiber in the filter can also be dull cotton. If the red light is still flashing, it means that there is a problem with the optical signal and needs to be repaired, and the staff will overhaul the optical fiber line.

If you check that the indoor line is installed firmly, you can give feedback to the local 10010 customer service ** or feedback through the Henghu China Unicom APP "Service - Fault Report - ** Fault Report", we will arrange professional engineers to deal with it for you.

1. LOS light off: normal state, the device has received the light signal;

2. LOS light flashes red: abnormal state, the device does not receive the light signal, so it cannot access the Internet;

If the LOS light flashes red, it is usually caused by the following conditions, which can be checked one by one:

1. The connector of the indoor pigtail connection equipment is loose, try to pull out the connector and plug it in again;

2. If the joint contact of the indoor pigtail connection equipment is poor, try to pull out the joint, wipe it clean with a cotton swab and re-insert it;

3. The bending of the indoor part of the optical fiber is too large or damaged, and the excessive bending or damage of the optical fiber will affect the total reflection transmission of the optical signal in the optical fiber, check whether the optical fiber is damaged, and straighten the optical fiber;

If none of the above adjustments work, it may be.

4. There is a problem with the optical interface of the equipment and the equipment needs to be replaced;

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

The broadband LOS light flashes all the time. If the LOS light of the broadband keeps flashing, it means that there is a problem with the network provided by the carrier. Or maybe there's a problem with the router that connects to your carrier's network. This problem can only be solved by the operator. You go to customer service ** to report for repair.

A flashing red light indicates that the optical fiber is broken, and other colors are generally blue or green.

What's going on with the mobile broadband cat los flashing red light, have you learned.

1. You can check whether the modem is connected normally.

2. If there are other modems at home, it is recommended to exchange the modems for testing.
