If the submarine fiber optic cable is blown up, will the cyber war still be fought?

it. How is there a possibility of large-scale cyber warfare in the future? Countless companies and institutions around the world rely on the Internet to blow up submarine fiber optic cables, and we have to pay a huge price.

First of all, companies and institutions can't communicate with the network, and staff in the field can't contact the company, and then CCTV and everything have to be stopped, and all kinds of can't be contacted, and then they offend the world. With such a big stake, the fart fiber optic cable, now everyone is evenly matched, and they contain each other, and no one can help anyone.

We don't know, we know, we know far less than the military, and we don't know exactly how many of these submarine cables there are, and whether they are in reserve, right, so I can't say. And if these submarine cables are broken, then communications and so on will be disrupted, and spies from other countries will not be able to use information to communicate with other than radio stations.

If it is blown up, it will definitely have an impact, and the impact is not small, but this inter-network line is mutual, and it has an impact on everyone.

Cyber warfare is not a communication war, but a battle between the data layer, and the connection with physical transmission is not very large.

I think how to define cyber warfare, whether there is no submarine fiber optic cable will be used for satellite wireless transmission, such as spies using satellite equipment for connection in China. Long-distance microwave transmission, etc., I'm afraid of people who have a heart!

If the submarine fiber optic cable is broken, there will be a disruption of communication with the United States, Japan and Australia, and the Internet can still be accessed in China, but it will not be able to access foreign countries**, and access to domestic ** will not be affected.

1. According to the surveys done, today there are more than 270 submarine fiber optic cables laid around the world, with a total length of nearly 1 million kilometers. International data communication exchanges use the Border Gateway Protocol, a decentralized autonomous routing protocol that allows users to control which submarine fiber optic cable is used to complete the international transmission of data.

2. For some residents of Singapore and Bengaluru, India, the farthest distance in the world may be that there is a submarine fiber optic cable about 3,000 kilometers long between them that can be used for communication, but they often choose to communicate through six submarine fiber optic cables across the Pacific and Atlantic Oceans. In many cases, the ratio of long-distance communication to direct-to-direct communication between them is 5:1.

4. At present, the world's longest submarine optical cable is the Asia-Europe 3 submarine optical fiber cable (seamewe 3), with a total length of 10,000 kilometers, led by France Telecom and China Telecom. The all-fiber cable network has a total of 39 landing points, connecting the four continents of Asia, Africa, Europe, and Oceania. Due to the increasing number of global fiber optic cables and transcontinental fiber optic cables, a problem at any node in the middle may affect the network communication of multiple countries.

The submarine fiber optic cable is broken, and you can still go online! Because the Internet is global, it's just a little slower.

The network of countries around the world can be seen as a large local area network, and submarine and onshore fiber optic cables connect them into the Internet, fiber optic cables are the "central nerves" of the Internet, and the United States is almost the "brain" of the Internet. As the birthplace of the Internet, the United States has a lot of web and IM (such as MSN) servers, and 9 of the 13 root servers that resolve domain names around the world are in the United States, and most of them log incom 、.

net** or email, and the data almost has to go around the U.S. to reach its destination. Connecting the "central nervous system" and the "brain" is the submarine fiber optic cable system, which is divided into two parts: shore equipment and underwater equipment. The shore equipment packages and transmits communication services such as voice, image, and data.

Underwater equipment is responsible for the processing, sending and receiving of communication signals. Underwater equipment is divided into three parts: submarine fiber optic cables, repeaters and "branch units": submarine fiber optic cables are the most important and vulnerable part of them.

As a high-quality, low-cost, and large-capacity transmission means, submarine optical cable systems are increasingly favored by people, especially the optical direct amplification multi-relay technology that uses EDFA (doped fiber amplifier) as a repeater, which increases the transmission capacity from 560MB S by 7 times, and has developed a submarine optical cable system that can transmit 5GB s signals per fiber.

Submarine optical cables are used for communication, generally laid in the deep sea or shallow sea, or rivers, and are not easy to be damaged and laid on the seabed communication optical cables, called submarine optical cables.

In times of war, if one country wants to cut off the Internet of another country, there is no need to blow up the submarine fiber optic cable!

For example, in the United States, as long as it shuts down the root domain name servers of the Internet, it will be very difficult for us to access the Internet!

China's Internet is connected to the world's four major World Wide Web servers in the United States (2 in the United States, 1 in Japan, and 1 in Europe) through an undersea cable erected on the bottom of the Pacific Ocean, through which Chinese Internet users access the world**.

A web is made up of countless lines. The continents are not composed of one or two lines, but are reticulated. If one line is broken, it can reach the destination through other lines, and countless submarine fiber optic cables are not afraid. Do all roads lead to Rome, this one does not pass, and which one leads is a time-consuming problem.

In fact, the Internet is spread by lasers, and the details are as follows.

In the event of an emergency in Asia, lasers are fired from above Tiananmen Square, and the lasers travel at a speed of 300 million light-years to the edge of the universe, and then from the edge of the universe to New York, North America.

After receiving the signal, New York emits a super-powerful laser that carries people to Asia at a speed of 600 million light years.

After that, the emergency is gone!

Landlord, do you understand?

Basically, submarine fiber optic cables are the mainstay, a small amount of data is transmitted by satellite, and the bandwidth of a satellite is only a few tens of gigabytes.

I think it's submarine fiber!

Your idea is understandable, but the point is that it doesn't work!

Because you call it all the same, think about it:

If you cut the public submarine optical fiber, will you not be able to use the network yourself?

Could it be that other countries that had nothing to do with the war were also hurt?

In this way, will they unite with your enemies to fight you?

China is mainly connected to the world through three sets of submarine cables: New Eurasia No. 3, Sino-US Submarine Cable and Asia-Pacific No. 2, which pass through the international submarine cable landing ports of Chinese mainland Shanghai, Qingdao, Shantou and other cities, and are connected to Japan, the United States and Europe respectively.

For example, the China-US submarine cable is a submarine cable that connects many countries in the Asia-Pacific region.

It follows the submarine cable landing site:

Shantou City, Guangdong Province, China.

Fangshan Township, Pingtung County, Taiwan.

Chongming County, Shanghai, China.

Okinawa Prefecture, Japan.

Busan, South Korea.

Minamiboso, Chiba Prefecture, Japan.

**Tamuning Village, Tanguisson Point, Coos County, Oregon, USA.

San Luis Obispo, San Luis Obispo, California, USA.

Of course, fiber optic cables cannot be erected at sea, but submarine fiber optic cables can.

Blowing up the fiber optic cable is the most stupid behavior in war, do you think that blowing up the fiber optic cable can avoid war? Not to mention how fast the network spreads, blowing up the fiber optic cable is undoubtedly forcing yourself into a dead end.

Compared with face-to-face war, war without gunpowder smoke is the sublimation of war.

Submarine fiber optic cables are a huge amount of engineering.

Submarine fiber optic cable, isn't that shark going to gnaw?

Haha, the landlord's question is very powerful.

Didn't the Taiwan side be broken once?

It's a submarine fiber optic cable, in fact, it's as simple as that. Hehe.

You're out, China is mainly an undersea fiber optic cable to Japan.

Submarine fiber optic cable, didn't there be a problem with the submarine fiber optic cable some time ago, resulting in Yahoo some ** can't browse normally! ~~

Hope it helps...

In the era of global networks, if the submarine fiber optic cable is cut, can our mobile phones still access the Internet normally?

In 2008, the Beijing Olympic Games, the pride of the Chinese nation!

Cyber warfare should be a war for the whole people, and all people are soldiers!

In favor of cutting the optical cable, cut the mess quickly.

If the submarine fiber optic cable is completely cut, everything will be solved.

It must be a submarine cable, the satellite bandwidth is too low, and the cost is very high. The submarine cable cloth is in charge of a special company and is fully equipped.

They are all connected by submarine cables, and the bandwidth of the satellites is small, and the cost is very high, 3 US dollars per minute.

Submarine fiber optic cables have been developed for many years, and now the technology is relatively mature, and there will be problems only when encountered.
