What is the difference between 2 megabyte fiber and 2 megabyte broadband?

Broadband refers to the network access mode with high transmission speed, and optical fiber is the transmission medium, not a concept. It can be understood that fiber optics are one of the ways to achieve broadband transmission. It should be said that it is optical fiber and double glue line, we usually pull the network cable at home is generally five types of double glue wire, the transmission medium is generally copper wire, data transmission is more like current, and optical fiber, the use of glass fiber, can be imagined into the mirror reflection of light in it, so the speed is much faster than the double glue line, and the loss is smaller than the double glue line, but its ** is very expensive, quite thick, and the core inside is similar to the hair, and the installation is also more troublesome, two sections of optical fiber are connected, to use a special optical fiber coupler,That's all I know.,I hope it helps.,Hehe.。。

Today's broadband is basically divided into optical fiber access and ADSL access ADSL currently has a maximum transmission capacity of only 10m Optical fiber has no such limitation Optical fiber and broadband are actually two different concepts Optical fiber is to transmit signals in the form of light pulses, with glass or plexiglass 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 are talking about broadband is for 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.

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 very strict definition, generally based on the current upper limit of dial-up Internet speed of 56kbps as the boundary, the access of 56kbps and below is called "narrowband", and the access mode above is classified as "broadband".

The most intuitive feeling is that broadband is the usual ** line, and optical fiber needs to go through additional application procedures, which belongs to the private line to access the Internet; Optical fiber is a dedicated line and is more expensive. Optical fiber is a dedicated line and has a fast speed. Wish.

The speed of broadband is exclusive, which means that the speed of 2M is enjoyed by you as a user. The optical fiber comes out of the switch, usually 10 users share the speed of 10m If these 10 users are at the same time, then a household is only 1m, if there is only one user**, then this user can reach a speed of 10m If it is a multi-terminal Internet access, the speed is divided equally by the computer

It is true that fiber optics are more stable than broadband. It is not easy to break down. However, the cost of fiber optics is generally slightly higher. If the cost is the same as broadband 2M, that person recommends that you choose optical fiber. If you still have any questions, you can ask me again.

First, the speed is different

The biggest difference between 200 megabyte broadband and 500 megabyte broadband is speed, 200m theoretical ** speed is about 20mb s, 500m ** speed is about 62mb s. Of course, this is all theoretical speed, and in combination with the actual situation, it may be a little lower. At the same time, a movie, 500 trillion will be faster; At the same time, 500 megabyte broadband** songs or **more**.

Second, the tariff is different

The most realistic is the tariff, because 200 trillion is cheaper than 500 trillion, so now many families will choose 200 trillion. However, the specific tariff still depends on how the operator in your region arranges. Telecom's broadband 200 trillion yuan is more than 1,000 yuan, which is relatively expensive.

Network speed is referred to as network speed. The higher the speed, the faster it will be and the shorter the time it will take to open the page. Generally, the speed of dial-up Internet access is 512k, 1m, etc., and the speed of wireless network is generally 11m or 55m.

Note: 1m=1024k, 1g=1024m) data transmission rate is one of the important technical indicators to describe the data transmission system. The data transfer rate is numerically equal to the number of binary bits per second that make up the data**, measured in bit second, and denoted as bps.

You can use the same light cat.

It is recommended to use a gigabit optical modem, because a 100 gigabit optical modem can only be used to use 100m inside.

Optical modems generally refer to optical modems. Optical modem, also known as single-port optical transceiver, is a three-piece optical fiber transmission equipment developed for special user environments. The device adopts a large-scale integrated chip, simple circuit, low power consumption, high reliability, complete alarm status indication and perfect network management function.

Optical fiber communication has rapidly developed into the main form of information transmission today because of its advantages of frequency bandwidth and large capacity, and optical modem must be moderated and demodulated to realize optical communication, so as a key component of optical fiber communication system, optical modem is receiving more and more attention. There are two types of optical modulators: direct modulators and external modulators, and optical demodulators are divided into two types: with and without built-in front amplifiers. Direct modulator and demodulator with built-in preamplifier are the focus of this project, direct modulation has the advantages of simplicity, economy and easy implementation, while demodulator with built-in preamplifier has the characteristics of high integration and small size.

Now 200 trillion can meet the Internet needs of most friends.

The downlink speed of 200 megabytes is generally about 25m s, and the uplink speed is generally about 25ms, but this is a theoretical situation, and the actual situation may be deviated due to various reasons such as network cables.

Take the length and width of the Great Wall broadband wing 200 megabyte broadband as an example, 200 megabyte broadband can transmit **1000 pieces in less than one minute, and ****428 songs in one minute. Now 200 trillion can meet the Internet needs of most friends.

Each operator is different, if you want high quality, and have enough budget, then directly choose as high as possible broadband**, if you want to find a cost-effective, cheap broadband, then you can use the wing length and width of the Great Wall broadband**, this**is very affordable, 200 megabytes of broadband a year only more than 700 yuan, equivalent to only a few dozen yuan a month.

Broadband process:

1. When you go to the offline business hall to handle it, pay attention to bring the required materials;

2. Official handling, this method is very convenient, you can handle it without leaving home, but you should pay attention to the formal handling;

The difference between 200 megabits, 300 megabits, 500 megabytes and 1000 megabytes of home broadband is actually the difference in bandwidth speed.

From the inception of broadband to today, the development trend is that the bandwidth is getting higher and faster.

From 256k and 512k in the early days, to 1 trillion and 2 trillion in the early days, and then to 10 megabits, 100 megabits, and gigabits, the bandwidth is getting higher and faster.

That's how broadband is growing.

As for the difference between 200 megabytes, 300 megabytes, 500 megabytes and 1000 megabytes, it is actually the difference between bandwidth and speed......The higher the number, the faster it will be.

It should be noted that there is a difference between what we call broadband speed and what we call file size and file transfer speed in our daily life, and there is a ...... difference

Specifically, the differences are as follows:

1. The speed of broadband is identified by b s. This b, which refers to the bit, is the basic unit of data.

2. The speed of daily copying of files is identified by b s. This front is called a b, which is a byte, and 1 byte is a byte, which is equal to 8 bits.

Therefore, the speed value of the broadband is converted to the number of bytes, which is divided by 8......

In this way, the transfer speed of 200 megabytes of broadband is about 25 mb s. With 1000 megabytes of broadband, its transmission speed will reach a state of 125mb s.

Therefore, as long as we do not have particularly high requirements for network speed, then it is enough to choose the mainstream network speed**.
