Ask the master about the difference between installing FTTB and ADSL

I know you're from Shanghai, and you can see the problem as soon as you see it, and it's very hot in Shanghai right now.

That's the end of the nonsense, let's get to the point, hehe.

Light to the floor (FTTb+LAN).

A Because it is a local area network and a shared network, special attention should be paid to security, for example, the probability of Trojan horses (especially gray pigeons) is several times higher than that of ADSL, so the security is not high.

b Shared bandwidth is generally 10M or 100M, ** speed is not guaranteed, fast is slow, depending on the number of recognition, but ADSL and he can not be compared with his fastest upload speed can reach 1M or 10M.

China Telecom's main product (ADSL).

A because it is a machine number, so the network speed can be guaranteed, generally now launched**bandwidth of 512kb 1m 2m 3m (can reach 8m, but not open for the time being) the actual **speed is (to divide by 8, the fiber mentioned above is the same) are 64 128 256 384 and so on, to add, you said 512kb can do 2m, it should be**reflected there, the rate provided by telecom is subject to the right click to save,**software because of the use of other technologies, The speed is not accurate, but you can show it when it comes to playing online games, and the higher the bandwidth, the better.

Most of the uploads are 512, and the company's private line can reach 1m, but it is actually 64 and 128, which is not comparable with optical fiber.

B In terms of security, ADSL is a single-machine single-household, not a shared network, so it will not capture packets, which is safer.

I've analyzed it with you, you choose it yourself, don't use a 100m fiber for 10 people, I'll let you choose AD, and you'll kill me, hehe.

It is recommended that you install FTTB which is definitely fast.

This is because FTTB and ADSL are not access technologies.

Therefore, if the installation does not interfere with each other, if it is slow, apply to the ISP to return the FTTB and re-apply for ADSL.

The most fundamental thing is speed. ADSL is based on traditional copper cable for carrier transmission, while FTTB is fiber optic directly to the building. The speed of optical fiber is much higher than the current speed of copper line carriers.

However, the biggest hidden danger of FTTB is that the optical fiber only reaches the building, and the bandwidth of the optical fiber is shared by all users in the building, and there is a problem of secondary distribution of bandwidth. If the economy allows, it is recommended to directly FTTH fiber-to-the-home, commonly known as exclusive fiber.

ADSL is the way of "** line + cat" to surf the Internet, which is used by general users, and the speed is generally 2m or 4m

FTTB is an optical fiber, which is used by high-end users, is stable and high-speed, and can provide 100M exclusive bandwidth.

ADSL is to communicate with ** wire.

FTTB uses optical fiber to communicate.

There is also a difference in speed.

ADSL: 100 MPbs or less (average speed 5 MPbs) FTTB: 100 MPbs or more (average speed 100 MPbs).

If you are using telecom broadband, then you had better call 10000 to consult and report for repair] first antivirus, and then report for repair so that telecom maintenance personnel come to repair without spending money, why not report for repair?..**Yes 10,000 local calls.

If you confirm that there is no problem with your own equipment, there may be a problem with the telecom side, and you will be able to hit ** warranty!

China doesn't seem to have a 6-digit ** number.

Don't mess around, just hit 10,000.

Call the telecom service **10000

The differences are as follows:

1. Set up a device

ONU equipment needs to be installed when different FTTb installations; FTTH's ONU device is installed in a box back somewhere in the building, A.

The user's installed machine is connected to the user's room through the five types of lines;

2. The installed capacity is different.

FTTB is an optical cable into the home, and users can use **, broadband, IPTV and other services through a single optical fiber; FTTH is a fiber optic cable to a stairway or to a building.

3. The network speed is different.

FTTH has a higher internet speed than FTTB.

FTTH is an optical BAI cable into the house, used.

Users can use a fiber through du

Services such as broadband and DAOIPTV only need to be installed with ONU devices.

Answer: FTTB is the optical cable to the corridor or to the building, the ONU equipment is installed in a box somewhere in the building, and the user's installed machine is connected to the user's room through the five types of lines;

The biggest difference between the two is that FTTH can provide users with higher internet speeds.

The BAI used by Great Wall Broadband is similar to the FTTB method, with optical fiber to the building DU channel, and a fixed DAO switch is placed at the building DAO crossing.

No need to dial up, can be dedicated to connecting many households, the disadvantages are very obvious, the more people who use it, the slower, it belongs to sharing the Internet. The telecom user is FTTH, the optical fiber goes directly to the user's home, and the Internet needs to be dialed up, but it is an exclusive broadband, so the speed is fast and the Internet is stable.

Upstairs explained very clearly, adsl to the house, through the ** connected to the cat and then connected to the computer, using the PPOE dial-up.

FTTb+DSL to the home is directly connected to the computer with a network cable, or the routing is also dialed using PPOE, and the two dialing methods are the same

Such a professional question doesn't add points, so let's explain it briefly.

FTTB+DSL is fiber-to-the-building, and then in-building wiring.

ADSL is a full copper cable.

I use 1m1500 yuan a year, you directly call **10000 and ask if there is 1500.

What you said should be e8**, it's okay, and it's bound to the fee.

Reference address. I think the ADSL of telecom is still okay.

The cheapest one is Tietong.

I installed 800 pieces a year 1m.

It's good to use it yourself.
