What is the concept of 1G optical cable entering the home and how to test the network speed

According to the questions asked, it can be judged that the main problem is whether to divide or not: network cable and network speed are two completely different concepts.

G's fiber optic cable means that your network cable is an optical cable that supports a maximum of 1G of data traffic.

G fiber optic cable to the home, and the application of broadband speed, is not a concept, do not be confused. The real internet speed should be the speed of applying for broadband. Applying for a few meters of broadband is the real traffic used.

It's like saying, no matter how good the highway is, if it is a tractor driving on it, it will not be fast, which is a truth.

3. Test the network speed, one is that it may be carried out with test software, and the other is the **normal software, observe its speed, if the application is 10m broadband, then its **speed should be: 10 8 = about the **speed. If it is really 1G broadband, its **speed is:

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 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.

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".

How to test your internet speed:

1.It is recommended to use a browser with IE kernel to test the Internet speed, otherwise the Internet speed test result may not be displayed;

2.When testing the network speed, if the local running program occupies the network bandwidth, the network speed test speed may be slowed down, such as: **Listen to songs (Kugou), **movies, BT**, etc., which will affect the accuracy of the network speed test such as telecom speed test;

3.If the network speed test is slower at night than in the morning, it is recommended to poke the peak time for the network speed test.

Which speed refers to the maximum network speed that the gigabit network card you use can support is 1G, and it is not that the traffic is 1G network speed! In China, 20M optical fiber costs 70,000 people a year, and 100M is the maximum! The maximum traffic in a province is 10g!!

So, the fundamental level of your Internet access is not fiber! I don't know the rest! Ask me how the Japs are doing!

Generally, in China, the 100 Gigabit network card is displayed at your 1G, which is 100M!! Got it?

Hehe, I was pitted by Little Japan.

What is the concept of 1000m? The maximum throughput of your PC's hard disk is 80M, and I'm talking about the internal transfer rate.

If you really have 1000M bandwidth, do you think your hard drive can digest it?

The best thing to do is to FTP test the speed.

First of all, I would like to ask if there is a 1,000 trillion share, and if so, it would not be surprising.

Then whether the computer you use can use Gigabit, Gigabit Internet speed impact is very big.

In the end, you still use the general one, and you won't have so many problems like others, even if there are, someone has encountered it.

If not, ask a professor at a university.

Fiber-to-the-home is the connection of a network to a home through a fiber-optic signal line.

The speed of fiber is related to the broadband speed requested at the operator, and can reach a maximum speed of 100Gbit s per lane. However, when the single-channel rate reaches 400Gbits or 1-Tbits, the signal will be severely lost due to the constraints of optical signal-to-noise ratio, nonlinearity, and dispersion.
