Due to the complex structure and passage of the seabed, repair of fiber optic cables can take weeks. Illustration. Specifically, the APG fiber optic cable had a problem since May 11 near Hong Kong. The cause of the fault was determined to be a shun fault. The repair process of this cable route lasted 5 days, during which the entire service to and from Hong Kong, China of APG project member partners was interrupted. On the morning of June 11, a representative of an Internet service provider (ISP) confirmed that the error of the APG fiber optic cable had been fixed. For the AAE-1 route, the incident on May 25 was determined to be a broken cable. The incident partially disrupted the carrier’s service to Hong Kong. According to the announcement of the company in charge of the AAE-1 cable route to Vietnamese ISPs, it is expected that the repair time for this cable line will last from June 22 to July 13. The two cable lines mentioned above are the ones with large capacity. The APG route, with the investment of four Vietnamese carriers, VNPT, Viettel, FPT and CMC, has been in operation since December 2016. With a maximum bandwidth of 54 Tbps and a length of 10,400 km, the APG route passes through many Asian landing points such as China, Hong Kong, Taiwan, Japan, Malaysia, Singapore, Thailand and Vietnam. Meanwhile, the AAE-1 line has been in operation since July 2017, with a length of 25,000 km and a total capacity of 40Tb/s. This cable route has the role of improving quality towards Europe and the Middle East as well as providing additional capacity and redundancy towards the connection direction to Hong Kong and Singapore. According to representatives of ISPs, when an undersea cable problem occurs, the network operators must navigate through other fiber optic routes or other directions of the route that is having trouble. Specifically, Viettel has routed and supplemented traffic for TGN-IA, APG routes to Singapore and AAE-1 to France. Meanwhile, CMC Telecom increased capacity via cable direction across Southeast Asia (A-Grid), connecting Internet from Vietnam through Cambodia, Thailand, Malaysia and Singapore. VNPT navigates and loads other cable directions that are operating stably such as CSC, AAG, IA, SMW3.

Postef’s fiber optic production project is an example of many high-tech projects supported by the Ministry of Industry and Trade. High return on investment August 2019, Postal Equipment Joint Stock Company (Postef) inaugurated an optical fiber factory with a capacity of 3.2 million km of optical fibers per year, marking a big step for domestic telecommunications technology enterprises to actively source raw materials, making Vietnam the first country in the world. Southeast Asia can produce this material. With a high degree of automation and precision, this is the first factory of Postef to apply smart production model Smart workshop. Data of fiber optic production stages is continuously updated to the server, and automatically transmits processing signals to equipment and machines. Perhaps, few people know that, since 2014, Mr. Tran Hai Van, director of Postef, has quietly cherished the idea of ​​​​building a factory. fiber optic production . At that time, Vietnam had dozens of units producing optical cables for optical communication networks, but all optical fibers for optical cable production had to be imported from abroad. Going into deep learning, Mr. Van became more confident knowing that the signal transmission system on optical fibers has been developing strongly in the world. In 2014, the world used 172 million km, it is forecasted that by 2020 it will continue to increase sharply to 234 million km. In Vietnam, fiber optic cables are formed at a galloping speed, especially international connection sea cables and transnational backbone routes. Problem after problem When “handing over” this idea to research and development associates, many problems arise. The economic problem is nothing to discuss, the investment efficiency is quite clear. But when it comes to technology, one problem follows another throughout the project construction process. First, it is necessary to clarify the technical characteristics, features – the main quality of the product is optical fiber according to the international standard G562, because in the Vietnamese market, optical fibers are mainly imported from manufacturers. famous as Sumitomo, Corning, Fujikawa, Furakawa. The second problem is the choice of spinning method. The horizontal pulling method has the advantage of being safe and convenient in the process of installing the workpiece, but the efficiency is not high due to the low pulling speed, up to 500 m/min. The vertical pulling method is more efficient, due to the 4-fold pulling speed, from 2,000 m/min, but requires a large tower height, 25 m or more. Final, Postef choosing vertical spinning technology due to its higher performance, better quality of spinning yarn and the world’s major yarn manufacturers such as Sumitomo, Fujikura… all use vertical spinning tower technology, therefore capable of receiving technology transfer from yarn manufacturers. In addition, there are dozens of problems on product selection and quality; product consumption plan; form and scale of investment; form of project management … in which, the problem of capital is the most difficult. Postef chooses vertical spinning technology due to its higher performance and better yarn quality. The problem is not that Postef can’t raise capital, but the regulation. The estimated capital of the project was more than 287.1 billion dong, excluding technology transfer costs, which was larger than the equity at that time (276 billion dong), so Postef had to come up with a plan to increase bond issuance. fixed capital is larger than project capital. During the implementation process, Postef also had to accept to transfer the entire investment project to build a multi-functional complex at 63 Nguyen Huy Tuong, Hanoi to another investor to focus on the fiber optic project. That said, in order for the fiber optic project to be successful, Postef had to struggle between many problems. Support two important stages khâu The most difficult thing in setting up a project is choosing equipment, technology and arranging capital with partners, which Postef overcame. Thoughts can easily “hug” the application to be listed on the list of high-tech prioritized for development investment under Decision 66 of the Prime Minister. But this is the first time creating a project of this type, so the file is not valid and has been returned. When “knocking” the Department of Science and Technology, Ministry of Industry and Trade, considered that the project really deserved preferential treatment under Decision 66, but it took the staff of the Department many months with Postef to complete it. standard set of documents as prescribed. Along with that, the Department also approved a budget of nearly 7 billion VND from the Ministry’s budget for science and technology activities for research to help Postef master the technological process of optical fiber manufacturing and the measurement technology process. Check and check product quality criteria. Especially, the factory was built to meet international clean standards level 6, designed and constructed by TAIKISHA Company (Japan) in the form of EPC turnkey. This is also the first factory of POSTEF to apply smart production model, smart factory and achieve the goal of smart factory by 2020. To date, the goals of a high-tech project on the economy and society of Postef have been achieved. But more importantly, the company’s fiber optic project added an extra hour, building confidence in its commitment to investing in smart manufacturing technology. High technology has 4 fields: Information and communication; new material; biotechnology; Smart production. These are very new fields in our country, while the Law on Bidding puts the standard of “capacity and experience” of enterprises participating in the bidding first, leading to a vicious circle of “chicken and egg”. Because it is the first production in Vietnam, “capacity” is not equal to foreign high-tech enterprises; Because they are not allowed to participate in the bidding, they do not have “experience” in bidding. With the risks when participating in the market as above, businesses are very hesitant in the process of setting up high-tech projects. On that pioneering path, there are many question marks when entering a new field, a new market that has not been clearly and clearly foreseen. Therefore, when there is the companionship of state agencies in project implementation, businesses feel warmer and more confident.

Italy plans to invest in a super-fast Internet with a speed of 1 gigabyte to provide it to all people by 2026. Artwork: jedsundwall.com Italy plans to expand its tax relief plan to quickly bring superfast broadband to buildings. The move comes as the country struggles to close the gap in digital development with the rest of Europe. The European Union’s (EU) third-largest economy now ranks second from the bottom out of the bloc’s 27 member states in terms of Internet usage. According to the latest EU data, about 17% of Italians have never used the web and only 13% of Italian households sign up for a super-fast broadband connection with a speed of at least 100 megabytes. Italy’s new government, led by former European Central Bank chief Mario Draghi, plans to spend more than 8 billion euros ($9.76 billion) from EU support funds on broadband, mobile networks. fifth generation (5G) and satellite technology and want a super-fast Internet connection at 1 gigabyte made available to all Italians by 2026. With this goal in mind, the Italian government is considering measures such as deploying fiber optic cables or exempting existing tax rates for residents when renovating the telecommunications network for their homes. This measure allows people to be partially exempted from the current 110% tax rate when renovating and upgrading telecommunications networks to help houses “become smarter”, thereby enhancing energy savings. quantity./.

Break boundaries in Internet access Elon Musk’s project of covering the Internet around the Earth has begun for users to sign up for testing. You can be one of the first to use this service even while living in Vietnam. Starlink’s ambition is to use 12,000 low-end satellites to cover the Internet to every corner of the globe. So far, this project has been successful in covering all over the Americas with a total of 1,261 satellites in orbit. The billionaire Elon Musk’s satellite Internet project also targets Vietnamese users. Currently, Starlink started allowing users to pre-order to use the service. Accordingly, when accessing the website of Starlink, users can easily choose familiar cities of Vietnam such as Hanoi, Ho Chi Minh City, Hue, Da Nang, Hai Phong, Can Tho … to register for history. use this service. Startlink will start providing satellite Internet services to users in Vietnam in 2022. However, to be one of the first users, users have to pay a fee of 99 USD (about 2.3 million VND) to “book”. Payment will be made via international cards such as VISA, Master Card. The kit offered will include a Starlink satellite pan, WiFi router, power supply, cable, and rack. In case of change of mind, Starlink will refund the deposit to the user. Assoc.Prof.Dr Pham Anh Tuan, Director of the Vietnam Space Center, said that Starlink is a satellite constellation project, in which thousands of small satellites are launched into low Earth orbit (abbreviated as LEO – Low Earth Orbit), located 550km from the ground. Internet signals will be shot from satellites straight down to receivers on the ground, then these devices will broadcast the signal through the local system or directly via wires connected to the customer’s Starlink router. The strength of satellite Internet is breaking down distance limits. Hilly areas, islands, complicated difficult terrain … still have simple internet access Satellite Internet works similarly to cable Internet, except that the system has more moving elements. When the customer accesses, the data request will be transferred from the computer to a satellite internet pan. This pan will broadcast a data request to a satellite orbiting the Earth. At this point, the satellite will send the received request to the ISP. The data is transmitted from the carrier to the satellite, then from the satellite to the satellite Internet pan, down to your router and into the computer. The more satellites, the more stable the signal. These satellites act like base stations, except that they are not obstructed by topographic space. Competition between suppliers According to Assoc.Prof. Dr. Pham Anh Tuan, the appearance of the SpaceX provider will create fierce competition from today’s telecom businesses. However, the bigger problem is that we do not have legal bases to manage cybersecurity for foreign suppliers. Therefore, in the coming time, there will be a need to consider legal frameworks to manage network information security, avoid bad and negative information, affecting socio-economic security. Assoc.Prof.Dr. Nguyen Huu Thanh, Director of the Institute of Electronics and Telecommunications, Hanoi University of Technology, this technology will create a big competition with network operators. Currently, Vietnam’s Internet is also relatively good, has coverage in remote areas, islands, but not as flexible as satellite Internet. Starlink is faster than optical fiber depending on the provider, but it is known that the bandwidth of the satellite Internet is very large, so it will compete greatly with current providers. The important point to compete here is the fee charged by the satellite internet provider, if it is too high, it will also be difficult to attract users. According to Assoc.Prof. Dr. Nguyen Huu Thanh, when the entire Starlink satellite system is put into orbit, this service will provide almost global coverage to populated areas. Users using the service only need to buy a pan to catch the waves, like a pan to watch TV. As for cybersecurity, if we talk about hacker intrusions and users, each person must be equipped with tools to protect themselves. Therefore, this problem is the same as with Vietnamese carriers only. The most important thing is to have fair competition policies, otherwise this market will be lost to foreign hands According to experts, Starlink can have coverage to the country or not depending on the country’s regulations. Currently, many countries have allowed Starlink to operate, but China and Russia will require the service to comply with special rules if they allow Starlink to broadcast on their own frequencies. Some countries prohibit the purchase, sale and use of ground-mounted Starlink receivers. In Vietnam, to manage satellite Internet, it is necessary to soon have appropriate regulations. In terms of feasibility, the cost of Internet services from the orbital satellite cluster is as low as that of Starlink is still 7-8 times higher than the price of fixed broadband Internet service in Vietnam. In the case of being deployed in Vietnam, satellite Internet service will be the solution to the problem of Internet coverage in areas with divided terrain such as hills, islands … In addition, the provision of satellite Internet services using low-orbit satellite beam technology promotes the development of the maritime and aviation industries.
