What is the difference between fiber broadband and regular broadband?

The most obvious difference is that the transmission medium is different, one is the first line virtual dial transmission is an analog signal, the other is the optical fiber transmission is an optical signal, which is more stable than the first line broadband. The second difference is that the bandwidth that can be achieved is not the same, optical fiber, as long as you pay for it, you can apply for the bandwidth of G, and it is impossible to achieve such bandwidth with ** line. The third difference is that the cost is of course not the same.

The equipment used in the two is naturally completely different, ordinary broadband is mainly ** line and moden, broadband is either optical cable machine + protocol converter, or optical modem. To learn more about service offers, click on the "****" customer service 220 below to answer for you.

Ordinary broadband is generally used.

The DU made of the ** line of bai, zhi but the ** line is used to transmit the network DAO signal, and its speed is very slow.

Edition. In contrast, fiber optic transmission.

The speed of transmitting the signal is much faster.

The advantages of fiber optic communication are:

1. Large capacity.

2. Attenuation.

3. Fast speed and stability.

4. Small size and light weight. Conducive to construction and transportation.

5. Good anti-interference performance. The optical fiber is not subject to strong electrical interference, electrified railway interference and lightning interference, and has strong anti-electromagnetic pulse ability and good confidentiality.

6. Save non-ferrous metals. (General communication cables consume a large amount of non-ferrous metals such as copper, aluminum or lead) 7. Low cost. Optical fiber communication was first used in optical fiber relay lines between the city's first bureaus, and then widely used in long-distance trunk networks, becoming the basis of broadband communication.

Ordinary broadband doesn't have that.

Broadband is an asymmetric number copy.

According to the transmission, fiber optics are the opposite of the attack on the data transmission.

BAI optical fiber transmits signals in the form of optical pulse, and uses DAO such as DAO glass or plexiglass as the network transmission medium. It is a transmission medium, just like twisted pairs, thick cables, thin cables, etc., except that its transmission speed is much faster than ordinary media, which can reach more than gigabit per second.

And what we are talking about broadband is the speed of our Internet access, the rate of dial-up Internet access has risen from 56kbps, but limited by the quality of the line, 56kbps should be the limit of the general modem, and now broadband is basically divided into optical fiber access and ADSL access. ADSL currently has a maximum transmission capacity of 10m, while fiber optics do not have this limitation.

The difference is that there is no specific definition of the person who is now wideband.

The difference between optical fiber and ADSL ordinary telephone lines

Yes: 1. ADSL is an ordinary ** line, which transmits ZHI electrical signals.

2. Optical fiber.

DAO material in-pass.

What is lost is the optical signal.

With the same distance, the optical fiber signal attenuation is reduced, and the interference from the surrounding environment is small, and the optical fiber can carry a maximum gigabit or higher bandwidth.

Today's broadband is basically divided into optical fiber access and ADSL access, and ADSL currently has a maximum transmission capacity of only 10 meters, while optical fiber has no such limitation.

Fiber optics and broadband are actually two different concepts.

Optical fiber transmits signals in the form of light pulses, and glass or plexiglass is used as the network transmission medium. It is a kind of transmission medium, just like twisted pairs, thick cables, thin cables, etc., but its transmission speed is much faster than ordinary media, which can reach more than gigabits per second.

The rate of ADSL broadband dial-up Internet access has increased from 2Mbps to 8Mbps, but due to the quality of the ** line, 8Mbps should be the limit of the general modem. If you want to get faster Internet speeds, you have to split the stream. Fiber optic transmission was born.

Optical fiber broadband and universal broadband are both used to transmit signals for telecommunications, and they are not the same as optical signals

1.Twisted pair 636f707962616964757a686964616f31333264653438

Twisted pair is a flexible communication cable, containing pairs of insulated copper wires, it is characterized by cheapness, so it is widely used, such as our common wires. Depending on the maximum transmission rate, twisted pair cables can be divided into Category 3, Category 5 and Category 5. The rate of Category 3 twisted pair is 10MB s, Category 5 can reach 100MB s, and Category 5 is up to 155MB S or more, which can meet the needs of multi-** data transmission in the future, so it is recommended to use Category 5 or even Category 5 twisted pair.

Twisted pair cables can also be divided into shielded twisted pair (STP) and unshielded twisted pair (UTP). Although the rate of STP twisted pair is lower (only 4MB S), the anti-interference is stronger than that of UTP twisted pair, so it is much more expensive. In contrast, UTP twisted pair** is generally around one meter per dollar, which is relatively cheap.

In addition, the popular names of commonly used 10m and 100m unshielded twisted pair cables are 10BASE-T and 100BASE-T, which can often be seen in the market. The RJ45 crystal head is used to match the twisted pair and the RJ45 interface of the network card, which is directly related to the stability of the entire network and cannot be ignored.

2.Fiber optic cables.

Fiber optic cable is a new generation of transmission medium, compared with copper media, fiber optics have been greatly improved in terms of security, reliability and network performance. In addition, the bandwidth of optical fiber transmission greatly exceeds that of copper cables, and the maximum connection distance it supports is more than two kilometers, which is an inevitable choice for building large-scale networks. Because the optical fiber cable has the advantages of good anti-electromagnetic interference, strong confidentiality, fast speed, large transmission capacity, etc., it is also relatively expensive and rarely used in household occasions.

At present, there are two different types of optical fibers, which are single-mode optical fiber and multi-mode optical fiber (the so-called "mode" refers to a beam of light entering the optical fiber at a certain angle). Multimode fiber is typically used for network connections in the same office building or in relatively close proximity to each other. Single-mode fiber, on the other hand, delivers higher quality data over longer distances and is often used to connect networks between office buildings or more geographically dispersed.

If optical fiber and cable are used as the network transmission medium, equipment such as optical transceivers need to be added, so the cost investment is larger, and it is rarely used in general applications.

The most obvious difference is that the medium of transmission is not the same

The first is the first line, and the virtual dialing transmits the analog DAO signal.

The biggest difference is that there is no limit to the upload speed, if it is an ordinary broadband, the maximum upload speed is only about 45.

You can use a wireless router to make a wireless splitter, so that you can have wired and wireless together, and that's how I did.

Not very big for home users bai, fiber.

The advantage of DU is reflected in the operator's side, you install 2M ADSL broadband DAO and 2M optical fiber, you can't feel what the difference is, if it is 8M ADSL and 2M optical fiber, of course, it is 8M fast, and the speed depends on the bandwidth you buy. . . However, the optical fiber is more stable and less interfered with, the optical fiber is the transmission medium, whether you use wireless or wired after entering the home, it doesn't matter whether it is optical fiber or not, the equipment operators have provided, you can get a router yourself.

Fibre broadband.

Copying is also a kind of broadband, but the traditional bai

The broadband is the use of ** line as the transmission carrier. Quality.

Zhi is poor, the transmission capacity is small, and the data transmission will be interfered by the surrounding magnetic field. Optical fiber broadband is to use optical fiber as the transmission medium for data transmission, optical fiber is plastic fiber to put it bluntly, its advantages are that light is not affected by the magnetic field of the surrounding environment in the signal transmission process, the data signal transmission quality is high, basically no packet loss, and the transmission speed is fast, the bandwidth capacity is large, and so on. So "fiber broadband" is better...

Even if it's expensive, it's worth it...

Don't be superstitious about fiber, that is.

Copy the operator's advertised bai

Pretense. Whether the network speed is fast or not, it depends on your bandwidth, such as if your ADSL access is **DAO line access, you open 4M bandwidth, if your LAN is optical access, only open 2M bandwidth, it is obviously ADSL access fast. If the bandwidth is the same, then of course it's the light.

After all, the light is more stable.

Fibre broadband is BAI

The data to be transmitted is converted from an electrical signal into a light signal for communication. DAO is equipped with "optical modem" capacity at both ends of the optical fiber for signal conversion. Optical fiber is the most ideal one of a variety of transmission media in broadband network, which is characterized by large transmission capacity, transmission capacity, low loss, long relay distance, etc.

Optical fiber transmission uses wavelength division multiplexing, that is, the data of multiple users in the cell are modulated into optical signals of different wavelengths and transmitted in one optical fiber. The difference between optical fiber broadband and ordinary broadband access mode is that ordinary broadband is electrical signal propagation, and optical fiber broadband is optical signal propagation.

The difference between optical fiber and broadband actually refers to the access mode of broadband, and ultimately directly affects the sound of the network.

Speed. We know.

The initial use of ordinary broadband is generally made of copper wire, but the line is used to transmit network signals, and its speed is very slow. In contrast, fiber optics transmit signals much faster.

Handling 5G is one step faster, the traffic is half cheaper than 4G, the broadband speed is 500M, and it is convenient and fast to log in to the online business hall of Guangxi Telecom to handle broadband, number card, traffic package, etc. with one click. Customer service No. 2 will answer for you.

Theoretically, the speed of 2M fiber and 2M ordinary DU is the same.

However, in fact, if the DAO uses 2M optical fiber to browse the web page, the speed is definitely faster than the latter, because it has less loss, less packet loss, and fewer bit errors.

After fiber-to-the-home, you can allocate the network resources in the door as you want, and use them as you want, and the service provider will not care about you. Therefore, after installing optical fiber, wired and wireless can definitely be used together, just like your original use.

Welcome to ask, the 6-star adoption rate is not much!!

Optical fiber is only a transmission medium of the backbone network, and the wireless network is also transmitted by optical fiber, including the backbone link of the mobile phone call.

For customers, whether the backbone transmission is made of optical fiber or coaxial cable, users are absolutely not felt, but for Internet service providers, optical fiber transmission can carry a larger amount of business, which is more convenient for maintenance. 、

For customers, it is directly linked to the network speed or depends on whether the user is installing a network of several meters, and another point is network congestion and latency (that is, the backbone network routing is related), which is only obvious to users who play games, but increasing bandwidth is not obviously helpful to solve this problem.

The BAI optical fiber broadband transmission in the community is 1G or 1000M, while the ordinary broadband ZHI electrical signal transmission.

I feel that with optical fiber, the speed of the Internet will be like light.

As fast as ever. In fact, fiber broadband is not a network that is as fast as light. Electricity.

What is the difference between broadband and network cable.

Fiber optic network speed is fast **expensive You can connect hundreds of units, and each one has a similar speed.

Broadband network speed is slow **low You can connect up to dozens of units, and the speed is a bit stuck.

I don't understand. Anyway, fiber optics are definitely not broadband fast. Everything else is the same.

What is the difference between fiber broadband and ADSL broadband?

Conceptual error.

Optical fiber is a transmission medium, and cable is also a transmission medium.

Broadband refers to the higher bandwidth of access, compared with the previous ** line dial-up method (narrowband).

There are currently two main ways to access broadband:

1. ADSL mode: It must be transmitted through the ** line (twisted pair), and then through MODOM (commonly known as cat) for digital-to-analog conversion, the bandwidth of ADSL from 512K-8M is no problem, if the rate is high, it will not be able to bear.

2. Optical fiber + LAN mode: It is through optical fiber access to the switch, and then the switch directly enters the home through the network cable and connects to the computer, and some people call this method optical fiber mode. In fact, only the switch line side is optical fiber, this way does not use cats, the maximum speed can reach 100m, most of the new high-end communities and Internet cafes are in this way.

3. Real optical fiber mode: It is the way to connect the network cable directly from the optical cat box to the computer, and the rate can reach 1000m.

It can be seen that broadband is not necessarily optical fiber, but optical fiber is generally broadband. The rate is defined by telecom at the local end, and has no direct relationship with the transmission medium.
