There are four types of broadband access methods: ADSL, LAN, FTTH, and PON

Cable television.

The original principle of coaxial cable transmission is different from that of ADSL, and the principle of coaxial cable transmission.

It's shared, while ADSL is exclusive. Knowing the principle, let's analyze which one is better. First of all, if the principle of coaxial cable transmission is shared, there will be a distribution problem.

The question of distribution is how many users of this coaxial cable are allocated together. The more users, the slower it becomes. This is not the case with ADSL.

Because of the exclusive broadband, the speed is stable, unless there is interference in the place where the line passes, which may affect the speed.

ADSL is similar to coaxial BAI ADSL, which is simple for general household use.

Du said that it is directly connected to the program dao control switch with the ** line, and the coaxial transmission is not good, and it is easy to be interfered with. But also look at the quality of the coaxial. Generally speaking, a good coaxial is very expensive, so the associated costs will also increase.

The speed of the network is related to the bandwidth that the communication company gives to the user, and it has nothing to do with what line is used.

Telecom also has network cable access, but it is rare to see if your community has such a service! Netcom is generally accessed with a network cable.

Hello, the broadband BAI access mode is divided into ADSL, ADSL

LAN, FTTH, and PON:

1. ADSL: Chinese name of the Chinese language: is an asymmetric number DAO word user line loop. It is patented with an existing pair of copper bina.

Access in Beijing, ADSL is well-known, in order to carry out civilian publicity, Telecom also gave it a nice name - "super first-line."

Answer". Access fee: The original ordinary ** ADSL line or the new ** ADSL installation at the same time will be charged a one-time access fee and a material fee of 300 yuan, and the ADSL line modification ADSL will be given as a gift, and the same initial installation fee will be charged.

Usage fee: Beijing does not currently provide ADSL unlimited monthly subscription service, but adopts an hourly charging method, and the excess part needs to be calculated and charged according to the normal time and time billing method.

Overall, Beijing's ADSL service is relatively monotonous, with only enough bandwidth for the "quasi-broadband" standard, and the usage fee is high, the method is inflexible, and the lack of unlimited monthly subscription services is scandalous.

Broadband in basic electronics and electronic communications is to describe the continuation or electrical circuits contained in or within.

1.There are currently a variety of broadband access methods: duadsl mode, optical fiber cell square type, and same DAO

Axis access mode, electric power broadband access mode 2The most commonly used by various operators are ADSL mode and optical fiber access mode3The most common type of mobile broadband access is cell fiber access, because China Mobile did not do wired access before, and later it mainly did fiber access.

When it comes to the good of broadband ADSL and optical fiber, I believe many people will tell you that fiber is good! Because the attenuation of the fiber decreases when the fiber distance is long, the uplink rate is fast, sometimes several times that of the ADSL uplink. Playing games, sending emails, and sending files are all fast, of course, it is worth recommending.

ADSL is a simple sentence: it is used for dialing up the Internet. It is also a kind of broadband Internet access that we usually call it.

If you want to be detailed: ADSL technology is an asymmetric digital subscriber line to achieve broadband access to the Internet technology, ADSL, as a transport layer technology, makes full use of the existing copper line resources, on a pair of twisted pair to provide 640kbps uplink and downlink 8Mbps bandwidth, thus overcoming the traditional user in"The last mile"of"Bottlenecks", to achieve broadband access in the true sense.

Optical fiber broadband is the abbreviation of optical fiber, which is a light conduction tool that uses the principle of total reflection of light in fibers made of glass or plastic. In everyday life, optical fibers are used for long-distance information transmission because the conduction loss of light in optical fibers is much lower than that of electricity in wires.

Finally, in terms of speed: fiber is faster than ADSL. Stability:

Fiber optics are more stable than ADSL. The disadvantages of optical fiber 1) are brittle texture and poor mechanical strength. (2) The cutting and splicing of optical fibers requires certain tools, equipment and technologies.

3) The shunting and coupling are inflexible. (4) The bending radius of the optical fiber cable should not be too small (>20cm). But none of this affects your online access.

Optical fiber Internet access also needs to be dialed, and the hotel you said does not need to dial because they use a router, and they dial on the router, and the following computers do not need to dial again.

Thank you for adopting.

2. Optical fiber 3 It stands to reason that optical fiber is much faster than ADSL, but because the number of users with broadband in your cell is too large, the number of users * 2m is greater than two to three times or higher than the total traffic of optical fiber, which is cell broadband. During the peak period, the broadband of 2m is distributed to each household, and the traffic is lower than that of dial-up Internet access 5, and it is recommended that the optical fiber is stable and radiation-proof

It must be that the fiber is fast, and now there are several kinds of fiber access, depending on whether you are the best. Like we have FTTH (fiber into the home) here, this is not like fiber to the corridor, this one is quite stable.

At present, there are many broadband access modes: ADSL mode, optical fiber cell mode, coaxial access mode, and power broadband access mode.

There are several access methods currently used by telecommunications:

1、adsl

ADSL is currently the most commonly used technology in XDSL. It is the English abbreviation of asymmetric digital subscriber loop technology, which makes full use of the cable resources of the existing fixed network, and can be transmitted without affecting the normal communication through a single line while realizing the transmission mode of communication and data services without interfering with each other.

Service characteristics: 1) The uplink rate is up to 640 Kbps, and the downlink rate is up to 8 Mbit/s.

2) Rate asymmetry: The uplink and downlink rates are not equal.

3) Cost saving: Internet access is independent of playing **, and can be used at the same time with **, without affecting each other.

4) Easy installation: just add voice separator and adslmodem on the ordinary ** line, and add a network card to the computer to use, and the installation is very simple.

ADSL connects the local office equipment and the user terminal modem through the second line (** line), and transmits high-frequency signals online. Due to its technical characteristics, there are several limitations:

1) The transmission distance is left and right;

2) The rate is greatly affected by the environment, such as distance, wire diameter, and interference.

Therefore, in order to ensure the normal use of users, the general rate is controlled within 2m.

2、vdsl

VDSL is the English abbreviation of Very High Speed Digital Subscriber Loop Technology, simply put, VDSL technology is a fast version of ADSL. Using VDSL technology, it can obtain a higher transmission rate than ADSL technology in a short distance, with a maximum downlink rate of 55Mbps and an upload rate of up to 55Mbps in VDSL.

The transmission distance of VDSL is about 500-1000M, and the rate is greatly affected by the distance, wire diameter, interference and other environments. Therefore, in order to ensure the normal use of users, 10Mbps uplink and downlink symmetrical rates are currently provided.

3. LAN Ethernet broadband access (FTTX+LAN) is a broadband access mode with optical fiber and Category 5 network cables. It connects optical fiber directly to residential areas and buildings, and then connects to each user's terminal through Category 5 cables to provide high-speed Internet access and other broadband data services for a wide range of users. LAN has the characteristics of high transmission rate and low investment on the user side.

It can meet the various needs of users at different levels.

Service characteristics: 1) High transmission rate and good network stability.

2) Easy to install, user-side investment saving.

Note: The LAN of China Telecom is very different from the LAN of other carriers. Telecom LAN is a VLAN mode, which allows individuals to exclusively enjoy VLAN and bandwidth, shielding various broadcast packets of the operating system, and has the characteristics of fast speed and good confidentiality.

4. Optical fiber dedicated line access.

Optical fiber access refers to the complete transmission between the central office and the user**. Optical fiber access can be divided into active optical access and passive optical access. The main technology of optical fiber user network is light wave transmission technology.

At present, the multiplexing technology of optical fiber transmission is developing quite rapidly, and most of them have been put into practical use.

At present, the more stable is, of course, the ADSL and LAN (optical fiber LAN) of telecommunications, the first of which transmits broadband signals to the user through the ** line, with moderate speed and stability;

The second type is optical fiber, which has a faster rate and less latency, but is less stable than ADSL, and is affected by conditions (for example, if you live in a place where there is no optical fiber, then it can't be installed).

There must be a ** to install dial-up Internet access, and then Telecom will install a broadband cat for you.

If you don't need to add anything to your own machine, you can use it directly.
