What is going on with the telecom fiber suddenly out of network

The light flashing red light means that the light modem receives no light alarm, move it, but maybe the light collection power of the light modem is still very low, turn off the power of the light modem and restart it, etc., if it is not good, call ** to the telecom to repair the fault.

Optical fiber is an abbreviation for optical fiber, which is a fiber made of glass or plastic that acts as a light conduction tool. The principle of transmission is 'total reflection of light'. Former President of the Chinese University of Hong Kong, Charles Kao and George A

Hockham was the first to propose the idea that optical fiber could be used for communication transmission, for which Charles Kao was awarded the Nobel Prize in Physics in 2009.

The tiny fiber is encapsulated in a plastic sheath, allowing it to bend without breaking. Typically, a transmitter at one end of the fiber uses a light emitting diode (LED) or a laser beam to deliver light pulses to the fiber, and a receiver at the other end of the fiber uses a photosensitive element to detect the pulses.

If the user's optical fiber broadband network is disconnected, the user can not connect to the Internet normally, and you only need to check whether the optical fiber modem device displays a red indicator to determine that the user's broadband network is disconnected, and the user only needs to restart the network connection of the optical fiber modem device to restore the normal network connection to the Internet.

If you can't solve the network networking problem, you can only call the telecom customer service to notify the broadband network maintenance personnel to come to solve the problem.

If you have a problem with your broadband, you can try to restart the fiber modem, if it still doesn't work, you can call 10000 and ask the staff to help you check or repair.

Excludes as follows:

The optical signal light of the optical modem keeps flashing red, which is due to the fact that the external network line is not connected, and the fiber line may be broken. The optical modem cannot read the optical signal. In this case, you need to report the fault and find a maintenance master to check and repair it for you.

An exclamation point on the network icon means that the network is connected, but Modern doesn't recognize your IP address.

Just set the IP address yourself.

If the optical fiber is broken or the interface is not connected properly, you need to find a lineman.

Check whether the network cable between the modem and the set-top box is normal, you can check whether the lights connected to the interfaces 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.

If you are using a router or a modem or switch with routing function, please remove the router, 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 the customer service **10000 for consultation.

Hello, if there are prompts such as "no service trail slow land" and "no network signal" on your mobile phone, there may be the following situations: 1Poor signal coverage or blind spots in the current area, such as in underground traffic tunnels or deep mountains and old forests.

2.If the SIM card is faulty or not plugged in, you can try to replug it. 3.

Wrong cellular network settings, such as turning off the mobile network or selecting the wrong network mode. 4.Carrier equipment failures or upgrade maintenance cause local base stations to be unable to provide services normally.

If the above solutions do not work, contact your mobile phone operator's customer service for consultation and resolution.
