The know-how of telecom broadband

Doing broadband nowadays is a long experience.

You really need to know more about yourself so that you won't be fooled!

Not all professionals will do what suits you. Only you can be responsible for yourself.

Below, I will give you a real calculation of the highest network speed according to the different ways of broadband access.

At present, there are three types of telecom broadband homes:

1, ADSL is used for telephone line access.

ADSL is an asymmetric digital subscriber line, which is a method of high-speed data transmission on telephone copper cable and a form of DSL.

It uses ordinary telephone lines as the transmission medium, and the highest achievable network speed is 8M.

This is the oldest way to enter the house, and it is almost rare in the world now.

2. Non-optical cable LAN

The transmission medium of LAN access is twisted pair network cable. Compared with ADSL using telephone line access, there is almost no need to compare the transmission speeds of the two, and LAN access is absolutely dominant.

Due to the limitation of the network cable itself and transmission loss, the highest bandwidth that can be achieved is1000 mm.

3. Broadband in 3.fttp

The transmission medium used in optical fiber access network is optical fiber. According to the penetration degree of optical fiber to user groups, optical fiber access networks can be collectively called FTTx.

It is mainly suitable for high-speed LAN access of commercial group users and intelligent communities. Now most new residential areas are connected in this way. The highest bandwidth that can be achieved is1000 m.

In addition to wiring, it will also send equipment cats or routers. It may be recycled when you leave the network in the future.

With the above understanding, is it much clearer?

Therefore, when someone cheats you, handle the 200M package, or even handle the more expensive, faster and more cost-effective 500M package, you should be careful.

Look at the broadband access mode of your home first, which of the above three is it.

If it's the second option, you can get the most expensive 500M monthly package by connecting a network cable to your home, and you can enjoy the Internet speed of1000 mm at most.

It is also a truth to run a 200M package. The fastest network speed that can be achieved is1100mm.

So if you do, I'm sorry that you were cheated by their so-called specialty, and you will laugh at you for not knowing anything, which is so deceptive.

You think they are professional and they know better, but that doesn't mean they will tell you and won't fool you into doing it.

Through the experience of these days, I hope to share it with the network whites and avoid unnecessary losses and troubles.

Life is also a lesson. Some people and things can only be seen clearly after experience.

This is my reflection.
