Telecom Broadband s fiber optic e is shown in blue

Hello, the display of different models of fiber optic cat signal light is different, generally showing red indicates that the fiber optic line is not passable, you can check the instruction manual of the fiber optic modem. The blue light of Network G or Fiber G of the modem is always on, indicating that the telecom network is normal. Still can't get online, please check your router and computer.

What is the difference between a fiber optic cat and a normal cat:

First, the optical fiber modem refers to the transceiver device that converts the optical Ethernet signal into other protocol signals.

Optical modem is a common name for optical modem, which has the role of modem. Fiber modem, also known as single-port optical transceiver, is a product designed for special user environments, which uses a pair of optical fibers to carry out single E1 or single or single 10Baset point-to-point optical transmission terminal equipment. The equipment is used as a relay transmission equipment for the local network, and is suitable for optical fiber terminal transmission equipment of base stations and leased line equipment.

Second, another type of fiber modem is FTTH fiber.

It is the terminal equipment ONU of EPON and GPON, which can realize the first-line opening of voice services, broadband Internet services and ITV digital TV services, and can be fully digital terminal equipment without adding any separators. The maximum rate of 100 Mbit/s that can be enabled on the modem is determined by the user.

Third, in fact, the functions of the fiber optic modem are the same as the ordinary cats we used before installing broadband.

They are all a conversion hub for converting signals, and only when they are installed can we use optical fiber or ** line to access the Internet. But there are some differences between fiber optic cats and ordinary cats: first of all, they are different in appearance.

As shown in the figure, ordinary cats and fiber optic cats. Secondly, there is the difference in principle. The optical fiber modem converts the optical etheric signal of the optical fiber into an electronic signal that can be recognized by the computer. Ordinary cats convert the analog signals in the ** line into electronic signals.

Fourth, can fiber optic cats and ordinary cats be interchangeable?

Many people will ask if the ordinary cat used before can be used as a fiber optic cat? Here we can clearly tell everyone that no. Because ordinary cats belong to ** line access, and optical fiber modems are professional optical fiber access, the interface protocols of the two are different, and ordinary cats cannot receive optical signals, so the two can be used universally.

The brand and model of the fiber optic cattery used in different regions are different, so the indicator lights are also different, if your broadband can be connected normally, then it is normal use, if you can't network normally, it is recommended that you replug the fiber optic cable connector and restart the device to try, if it still doesn't work, you can directly report to the operator's customer service for repair.

The above information is for reference only, gigabit in the city, C-position debut. 5G dual gigabit**, 1000M broadband, 60G traffic for the whole family, details can be found in Guangxi Telecom's online business hall. Customer service number 193 will answer for you.

Solid blue indicates that the synchronization with the computer room is successful, and the line from the computer room to home is normal.

The reason for the blue flashing of the telecom broadband fiber optic light is that the carrier's equipment is damaged.

If you still can't access the Internet after restarting, and the equipment on the carrier's side is damaged, it is recommended to call telecom customer service for repair and let the staff repair it.

Router Symbol Function:

1. The sys system status indicator flashes in normal state.

2. The WAN status indicator is solid or flashing in the normal state. The LAN status indicator is connected to the interface corresponding to the computer, and the normal state is always on or flashing.

3. The power supply of the power meter flashes to indicate that the connection is abnormal.

4. The LAN status indicator is always on means that the connection is normal, flashing means that there is data transmission, and not lighting means that it is not connected or the connection is abnormal.

5. The ADSL status indicator is always on to indicate that the central office device is connected, and flashing indicates that it is connecting or the connection is abnormal.

A router (also known as a pathfinder) is a computer network device that can send data to its destination by packaging a network (selecting the transmission path of the data). Router scrambling is a device that connects two or more separate networks, and the routing works at the third layer of the model, which is the network layer. <>

A blinking blue telecom broadband fiber light may indicate that there is a problem with your broadband connection. This is usually due to network failures or misconfigurations. If your broadband connection and Wi-Fi are not connecting, then you may need to check your modem or router.

In many cases, when the telecom broadband fiber optic light flashes blue, it means that your device is trying to establish a connection, but something is wrong. This can be due to a communication issue between devices, such as a router or modem that fails to communicate through the correct network port.

There are a few ways to go about this. First, you can restart your modem or router. This will usually help fix the connection issue and get your device back connected to the internet.

Second, you can try setting up the network connection again on your device. This may involve deleting the existing network configuration and recreating a new network connection.

Finally, you can try to resolve the issue by contacting your internet service provider. They may need to remotely access your modem or router and do some diagnostics to determine the root cause of the problem. In some cases, they may also need to send a technical support person to your home for repairs and configurations.

In conclusion, the telecom broadband fiber optic light flashing blue indicates that there is a problem with your broadband connection, and if your own attempts don't solve the problem, you can contact your network service provider. They will help you troubleshoot the issue that is causing the lights to flicker and restore your internet connection. <>

The blue light of Network G or Fiber G of the modem is always on, indicating that the telecom network is normal.

If you can't get online, check your router or computer.

In general, there are several possibilities:

1. Optical fiber break (more likely);

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

3. Optical modem failure (small possibility);

4. Failure of the uplink splitter (generally this kind of failure, the neighbors around you can't use it.) As long as you are sure that the pigtail behind the light cat has been connected correctly, you can only report for repair and let the master come to check. China Telecom dials 10000, China Unicom dials 100010, and China Mobile dials 10086.

Please judge according to the model and brand, most of the E indicators are green, and the flashing status of the light modem E lights of different brands and models means differently, for example:

1. ZTE F460

2. Fiberhome HG221

3. Huawei HG8120R

Hello generally the green light is normal, you can restart the broadband cat to give it a try.

Depending on the manufacturer of the modem, the color of the indicator (including the name) will be different. As long as it can be used normally, it will be fine.

If you can access the Internet normally, it's no problem.

China Telecom's optical fiber router network e flashes red light with the following faults.

1. The light port of the computer room emits low or no light, causing the user's optical modem to work abnormally, and 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 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.

No matter which of the above three situations occurs, users basically can't solve it, and they can only report the fault.

Hello, the flashing red light of the optical modem means that the optical path is not working, it may be that the optical fiber is broken, and it needs to be repaired by maintenance personnel, please report for repair. Telecom service number 10000.
