Analysis of submarine cable data

The balance between ultra-low loss and cost optimization is sought in the face of more submarine cable application scenarios.

More than 95% of global transoceanic communications require undersea fiber optic cable, once the cable is damaged, communications will be seriously affected.

SAN FRANCISCO, 90006, USA, July 23, 2022 / — The Importance of Undersea Fiber Optic Cable
Today’s society has been covered by a variety of networks, the network has been closely linked with the countries of the world, and an undersea fiber optic cable to ensure that the global network between major regions can interconnect the artery main. So what is the importance of the submarine fiber optic cable, once cut the American economy will collapse?

The fiber optic submarine cable has not been introduced for a long time, the world’s first submarine cable was built in 1988, this cable connects Europe and the United States, a total of 6,700 kilometers long.
To date, more than 90% of transnational data transmission in the world relies on submarine fiber optic cables. According to statistics, the total length of the world’s submarine optical fiber cable has reached 900,000 kilometers, which can circle the earth 22 times.

While the United States benefits from the enormous geopolitical advantages brought by the ocean, it also has to deal with the disadvantages of being far from the major continents. Due to the relatively low cost of maritime transport, economic trade is not seriously affected, but in order to maintain smooth communication with the world, it is impossible to do without fiber optic submarine cables.
More than 95% of the world’s transoceanic communications need the help of undersea fiber optic cable, once the fiber optic cable under the ocean is damaged, communications in the United States and around the world will be seriously affected.

There are 13 root servers worldwide, 10 of which are in the United States.

ZMS Cable Manufacturing’s experience and expertise in challenging construction projects around the world, from underwater survey – design – installation – to protection, provides a full range of optimal solutions for underwater cables. sailors.

The impact is not only on the United States, but also on other countries, because the only IPv4 DNS master root server in the world is in the United States, and once the American cable is cut, the global DNS will be affected. Although several secondary root servers have been installed outside the United States, they can only guarantee access to a portion of users.
If the deep ocean cable is cut, the major DNS service providers should have prepared a plan, and the impact on individual users will not be too great. But for many multinational enterprises, such as securities, banks and other international institutions, a large amount of data from these institutions will directly lead to business stagnation and even lead to large losses if they cannot interact with data from servers in the United States.

In addition, the United States of Google and other major Internet technology companies are also building undersea fiber optic cables, and will soon build an undersea fiber optic cable network. It also means that with their increasing investments in fiber optics under ocean cables and other related facilities, these American Internet companies will have more and more control over the international Internet in the future.
If these undersea fiber optic cable networks are cut, in a short period of time, these Internet companies will also suffer huge losses.

To prevent this from happening, the United States is also looking for an alternative to the fiber optic submarine cable program.
For example, within the framework of the “Starlink” program, various spatial Internet solutions are tested. But the essence of the satellite in the Starlink program is a WIFI router, the role is to connect the terminal and the local backbone network. Although the network problem can be solved for a short time, fundamentally, the transoceanic space communication technology in terms of bandwidth, delay, anti-jamming and cable in the ocean is not up to standard.
The satellite laser broadband communication being developed at this stage is not mature enough and is susceptible to interference, completely unable to meet transcontinental communication needs. In other words, in the next 3 to 5 years, underwater optical fiber will remain an irreplaceable means of transoceanic communication.

Damage and repair of submarine cables
or underwater communication cables are highly customized products that not only have to withstand high voltage levels internally, but must also be corrosion and abrasion resistant externally due to their presence in the deep ocean.
It is very easy to damage an underwater fiber optic cable, but not so easy to repair a section of it. When the submarine cable is broken, a professional repair ship will rush to the scene.
If the cable is located in shallow water, robots can be sent to the water, the cable will be towed to the surface.
If it is an area of ​​6500 feet (approximately 1980 meters) or more on the high seas, the repair vessel will use the specially made grappling hook to grab the fiber optic cable and then lift it to the surface to repair it . Sometimes the grappling hook cuts the damaged fiber optic cable and the repair vessel lets both ends out of the water for repair.

We know here, buried in the depths of the submarine communications cable at the end how important, when cut, will have a huge impact on the American economy.
But if the United States can collapse, I am afraid that the number of fiber optic cables cut, the United States and the world are connected to some undersea fiber optic cables, and Russia wants to rely on their power to cut all those cables is not very realistic.

At present, the submarine network carries more than 99% of intercontinental communications data traffic and has become an important part of the entire optical communications infrastructure.
For various marine fiber optic cable application scenarios, ZMS Cable has introduced a variety of fiber optic products that strike a balance between ultra-low loss and cost optimization for Space Division Multiplexing (SDM) systems ) repeaters and marine repeaters.
Provides industry-leading attenuation performance for ultra-long-range, high-throughput SDM systems.
