What is the difference or benefit between broadband and fiber?

Broadband generally refers to ADSL broadband. Difference Between ADSL Broadband and Fiber Broadband::

1. Comparison of applicable populations.

ADSL is suitable for dispersed users, while FTTH+LAN is aimed at a relatively concentrated user group.

2. Comparison of cost and **.

The advantage of fiber broadband is that the cost of networking equipment such as hubs and Ethernet switches is low, and users do not need to install ADSL modems, which is the capital for Ethernet to compete with ADSL. Fiber broadband users have less investment and lower cost**. ADSL uses the existing city network and the computer room of the exchange bureau, which cannot be separated from the fixed network, and is subject to geographical restrictions on use, and at the same time, the cost of the product has also increased.

3. Access mode.

FTTX+LAN is a fiber-to-the-building network cable to the home, and ADSL is an ordinary ** twisted pair cable. In comparison, the access of LAN users is simpler, and they can be accessed using routers, switches, and even ordinary network cards. At the same time, because the LAN mode uses optical cable + Category 5 line to carry out integrated wiring for the community, the quality of the line has been better guaranteed.

4. Stability and anti-interference.

ADSL has general requirements for line quality, and when the line quality is not good, it will affect the stability. When the transmission rate is higher, the greater the impact of attenuation and crosstalk on the signal, and sometimes the network rate will drop and the connection will be dropped.

The FTTX community broadband adopts a different network from the ** network, and the corridor switch and the community center switch, the community center switch and the local office switch are connected through optical fiber, with high network stability and strong reliability, not to mention the problem of mutual influence.

5. Speed comparison.

Due to the asymmetric digital technology of ADSL technology, the speed is asymmetrical and the network speed is limited. While LAN uses symmetric digital broadband technology, has a wider frequency band, and the bandwidth is variable, which can continuously increase the speed, while ADSL cannot meet the market demand for access rate in the future due to the small potential of bandwidth scalability.

Comparatively speaking: ADSL broadband is low cost and affordable, but the network quality is relatively weak and it is easy to be interfered with by the outside world; In comparison, fiber broadband is safe, stable, fast, and has a small delay, which can meet the needs of groups with high demand for broadband, but the cost is high, and the cost is higher.

1. In terms of quality, fiber is better than broadband.

2. On stability. Fiber is better than broadband.

3. In terms of transmission speed, optical fiber is better than broadband.

4. In terms of latency, fiber is lower than broadband.

5. On **, optical fiber is higher than broadband.

You can do it! Cross-network latency, those optical fibers can't solve it!

Optical fiber and broadband are not the same, and the main differences are the following four points;

1. The optical fiber is symmetrical on and off the network, while the ordinary broadband, which is commonly referred to as broadband, is asymmetrical.

Optical fiber Internet access is dual-channel, if it is a 10m optical fiber, theoretically up and down can reach 10m, 2, optical fiber Internet has a fixed IP, and broadband only has dynamic IP.

The fixed IP is the public IP, which is unique in the world, and the dynamic IP is to be changed once in a few days, 3. Optical fiber Internet access is exclusive, while broadband is shared.

Many companies are complaining that the network is very slow during the peak period of Internet access, and enterprises that use optical fiber Internet access will not have the word peak period, of course, this exclusive and sharing are relative, and there is no absolute exclusive enjoyment in the Internet.

4. The access level of optical fiber Internet access and broadband is different.

The usual network layers include the core layer, aggregation layer, and access layer. The core layer is the level of interconnection of major operators, the aggregation layer is the level of optical fiber access, and the level of broadband access is at the access layer.

What is the difference between fiber broadband and ADSL broadband?

Broadband and fiber optics are not two concepts that can be compared. The question should refer to the broadband accessed by the original ** line or network cable, and the optical fiber should refer to the broadband accessed by optical fiber. The difference between the two is different in the transmission medium, and the network architecture is also different.

There is no strict definition of "broadband" itself, and the broadband standards referred to by different periods, regions, and organizations are different.

From a general point of view, it is able to meet the needs of various ** transmission on the network that people can feel, so it is also a dynamic and developing concept, and any Internet access method that exceeds the "broadband" standard can be called "broadband".

The "optical fiber" referred to in daily life refers to "optical fiber broadband", which is one of the access methods of "broadband" and a type of "broadband". Other non-fiber access methods are also called "broadband" if they can meet the criteria of "broadband".

Broadband transmits an electrical signal, while optical fiber transmits an optical signal, and that's the difference.

Authoritative Answer: The difference between fiber optics and broadband ADSL.

This refers to the way broadband is accessed. There are a variety of broadband access methods to the user side, the most commonly used are ADSL, VDSL, FTTb+LAN, and optical fiber access, as well as wireless access and power supply modem access. The access mode is not directly related to the bandwidth requested, that is to say, the broadband of 2M can be achieved in either way, and the speed can reach 2M.

It's just that the path of implementation is different. It's like going from place to place, walking, taking a car, a plane, or a train. Because you are applying for 2M, no matter which way you use the access, you can meet your requirements.

If the network speed is increased to gigabit in the future, then ADSL, VDSL, FTTb+LAN, and wireless will not be able to meet the needs, and optical fiber can meet the requirements, but it is necessary to replace the equipment on both sides of the terminal and replace the 100 trillion device with 1000 megabytes.

Broadband refers to the network access mode with high transmission speed, and optical fiber is the transmission medium, not the same concept.

It can be understood that fiber optics are one of the ways to achieve broadband transmission.

Today's broadband is basically divided into fiber access and ADSL access.

ADSL currently has a maximum transmission capacity of only 10M.

Fiber optics have no such limitations.

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.

And what we call broadband is the speed of our Internet access, and the rate of dial-up Internet access is from.

Ascended to. 56kbps, however, limited by ** line.

The quality of 56kbps should be average.

The limit of modem. If you want to get faster Internet speeds, you have to split the stream, so in recent years, a variety of broadband access services have emerged. So, what is broadband? In fact, there is no strict definition, it is generally based on the upper limit of the current dial-up Internet speed.

56kbps for the demarcation, will.

Access of 56kbps and below is called "narrowband", and access methods above it are classified as "broadband".

What is the difference between fiber broadband and ADSL broadband?

Network cables and optical fibers have different material structures, different transmission distances, and different application scenarios.

At present, most of the inner core of optical fibers are glass fibers, also known as optical fibers, fibers made of light in glass or plastic, and use the radiation function of plastic to play the purpose of light energy conduction. Most of the cores of network cables are made of copper cores.

When the network cable transmits the network signal, if the distance beyond the network cable itself can bear, the signal will be attenuated, and the signal will be interrupted in severe cases. In long-distance transmission, optical fiber has incomparable advantages. The transmission distance of single-mode optical fiber can reach 10-20km, and the transmission distance of multi-mode optical fiber can also reach 2km-3km, which is much higher than the transmission distance of network cable.

Network cables are mainly used for connecting devices, and optical fibers are mainly used for broadband communication.
