Why does telecom say that LAN is an obsolete product now?

lan = local area network, the Chinese translation is "local area network".

ADSL = Asymmetric Digital Subscriber Line Asymmetric digital subscriber line, simply put, 2M ADSL, your ** speed can reach the theoretical maximum value of 2048K s, but the upload speed is generally only 512K s, no matter how high the downlink is only 512K! This is something that many people don't know!

LAN is a network name, and ADSL is an access method, and there is no point in comparing the two in a strictly literal sense!

The "LAN" referred to by the telecom business hall should be the Ethernet (Ethernet) access mode, which is often referred to as community broadband.

And I can responsibly say that the obsolete products of LAN he said are deceitful!

ADSL is the product to be eliminated! ADSL technology is a very old technology, uplink only, downlink, and up and down asymmetry, ADSL The biggest advantage is that you can use a modem to go directly to the landline line, as far as the current Chinese civil is concerned, there are still many communities that do not have LAN lines, if you want to erect LAN lines It takes a lot of money and investment, but now Chinese residents have ** landlines, so ADSL has the current market!

And in terms of form, sooner or later ADSL will have to be replaced by LAN!

Now the new real estate is connected to LAN in advance, many elevator apartments even fiber to the home, and Ethernet technology provides 100M-1000M bandwidth, and the upper and lower lines are symmetrical, and the future office room, are network + digital TV + visual ** three-in-one, only LAN can hit such a amount of data, and ADSL is just a transition!

Now the intervention of community broadband, the so-called port is to add one more switch, that's all, but whether the fiber bandwidth is enough is not a problem of the port, it is a problem of data traffic.

At present, the Ethernet technology for LAN access is not yet popular, but in the future, ADSL will definitely be eliminated! In its place, it is Ethernet technology for LAN access.

The lan that the staff said was eliminated, and I can only express contempt!

No, he's fooling you...

LAN is the network...

ADSL is also a type of LAN product.

It's good for them to expand their equipment. Don't install an AD that's slower than a 2m LAN. And unstable.

Obviously fooling you,LAN is a broadband Internet access method that was launched after ADSL,As far as their own transmission rate can explain the problem,ADSLThe maximum transmission rate can also be 8M,And LAN is based on Ethernet,You can avenue 100M rate,Which one do you say?,He said that there is no LAN port,It is estimated that it is installed,It is recommended that they add a switch to solve it。

Lie to your !! I'm Tietong. No empty ports?? Open the personnel and add a switch to have a port!! ADSL is about to be eliminated!

LAN generally has those cells that will upload faster than ADSL.

Hello. It is recommended that you change to fiber broadband, the fiber broadband network is more stable and faster, please visit the online business hall for details.

LAN (Local Area Network) is a broadband access mode provided by China Telecom with fiber to the cell and network cable to the home, which can meet the needs of gigabit to the cell, 100 megabit to the corridor, and 10 megabit to the home, and the user only needs a computer and a network card to easily access the broadband Internet of China Telecom, which has the characteristics of fast speed, good stability and easy installation. The following is a typical LAN networking diagram:

There is no need to use a cat for signal conversion when the LAN cell is accessed, because it is a digital signal that enters the home.

However, you still need to make a PPPoE virtual dial-up before you can access the Internet.

The access you're saying requires you to reboot the cat, and it's possible that your home gateway device has console access disabled.

If you do not currently have problems with your network access, it is recommended that you do not change the default settings of your telecom distribution equipment to avoid causing you trouble.

You are welcome to pay attention to the latest preferential activities announced by Anhui Telecom's online business hall and official Weibo.

If you still have questions, please keep asking. Have a great day, thank you!

This kind of LAN cell is the most troublesome, try again after the router reset.

That is, if you use a router, you need to plug in the LAN port on the router, not the WAN port.

The most important thing is optical fiber, less after-sales maintenance in the future, direct optical fiber to your home, ** is the same, the network cable can be transmitted up to 100 meters, and there is a certain attenuation, and the optical fiber is not. On the whole, optical fiber is still good, and the general environment is also a trend...

Well, this problem, first of all, the current network trend has always been optical into copper, that is, optical fiber networks are popular, and copper wires (such as ** wires, coaxial cable lines, etc.) are gradually withdrawn from the market. At present, the mainstream network is fiber-to-the-building, and then twisted pair cable from the building to the user's home (i.e., FTTB+LAN) mode. Major operators are now working hard to do fiber-to-the-home, that is, the network of optical cables directly to the user's home (i.e., FTTH).

The previous online approach (ADSL) is being phased out. When operators say optical fiber, they generally refer to these two types. That is, FTTb+LAN or FTTH mode.

Let's talk about the ** line adsl method. This way is to achieve high-speed Internet access by transmitting signals through ** lines, but due to line and technical limitations, the maximum network bandwidth that ADSL can achieve is 4 trillion (some operators say 6 trillion bandwidth, I have experienced, the speed can not even reach 5 trillion bandwidth, and it is very unstable, but I heard that ADSL2+ technology has come out, but it has not yet been promoted, and it can reach a maximum of 16 trillion network bandwidth). It is basically no longer able to meet the current and future network speed needs.

In the FTTb+LAN mode, the maximum network bandwidth that can theoretically be achieved is Gigabit, but now it is generally up to 100 Gigabit (all limited by network cables and switch ports). In addition, such a technology requires the installation of equipment boxes upstairs, which must be connected to electricity, waterproof, and regularly maintained, and the construction is also more troublesome. However, the technology is relatively mature, so most places still use this method now.

The next step of FTTH mode is to directly send the optical cable from the computer room to the community, and then distribute it to each household after passing the optical splitter, such a technical advantage is that the optical splitter itself does not need a power supply, and the maximum bandwidth of the optical cable is theoretically 1000G (the current FTTH time-division multiplexing technology can reach the bandwidth of each household at least), and does not take the signal, safe, stable signal, not affected by bad weather, and the construction is also very simple. Therefore, it is a fiber optic cable scheme that is about to become popular and is strongly promoted by major operators.

Hello, LAN technology mainly uses Ethernet technology to serve users in the form of information cells, and uses high-speed switches in the central node to provide users with FTTZ (fiber-to-the-cell) + LAN (network cable-to-home) broadband access.
