6 undersea cable routes connecting Vietnam to the world

The problem of undersea fiber optic cable is now too familiar to us because of its increasing frequency, the repair time lasts a few weeks, sometimes up to a few months.

The economic impact is so obvious that many people can’t even access Google or send and receive mail. Website is inaccessible, so visit, reduce revenue, run ads ineffectively.

Currently, the Internet connection from Vietnam to the world, besides the land cable routes across the northern border, is currently based mainly on 4 main undersea cable routes: IA, AAG, SMW3, and APG. In which, IA, AAG docked in Vung Tau, and 2 routes SMW3 and APG landed in Da Nang.

1. AAG (Asia-America Gateway) – Main Gateway

  • Capacity: 2.88 Terabit/s
  • Length: 20,000 km
  • Connection: Southeast Asia with America.

The AAG optical cable route (full name is Asia-America Gateway) was put into use in November 2009, with a total length of 20,000 km, a total capacity of up to 2 terabit/s and a total investment of $560 million. . AAG lands in Vietnam at Vung Tau, located in section S1 and has a length of 314 Km.

Before 2009, Vietnam’s international internet connection completely depended on two undersea fiber optic cables, TVH and SMW3, with quite limited traffic. TVH has a design traffic of only 560Mbps in each direction, SMW3 up to 320Gbps, the rest is connected via land cables.

AAG is an undersea fiber optic cable that plays a very important role for Southeast Asia in general and Vietnam in particular, most of the major carriers in Vietnam are exploiting, including VNPT, FPT, Viettel and CMC. . Currently, the international transmission line, the speed of Vietnam’s Internet to the world depends mainly on this fiber optic route.

For carriers that do not have many other backup lines, when the AAG problem occurs, Internet users are required to wait for the repair to be completed. The sad thing is that AAG often has problems, in the last year, 2017, Canh Me recorded 7 times this cable line had to be repaired.

2. APG (Asia-Pacific Gateway) fiber optic route

  • Capacity: 54.8 Terabit/s
  • Length: 10,400 km
  • Connections: China, Hong Kong, Japan, Korea, Malaysia, Taiwan, Thailand, Vietnam, Singapore.

The APG optical cable route (full name is Asia Pacific Gateway) was put into use in 2016, with a total length of 10,400 km and is the latest undersea cable connecting to Vietnam recently. The total transmission capacity of 54.8 Terabit per second is also the largest Internet gateway in Vietnam ever, leading Asia today.

4 years is the time it takes to invest, deploy and complete the construction of this cable line.

APG fiber optic cable has extremely good speed, built by APG consortium including Facebook and 11 largest telecommunications service providers in the region. In which, Vietnam with leading Internet service providers such as FPT, Viettel, VNPT and CMC. This is a completely new undersea fiber optic cable, promising to bring optimal performance and benefits for Internet service quality to users.

As the AAG undersea cable is often malfunctioned by a series of incidents, APG is expected to help improve Vietnam’s international transmission traffic more stably.

3. SMW-3 cable route (SEA-ME-WE3 or South-East Asia – Middle East – Western Europe 3)

  • Capacity: 320 Gbp/s
  • Length: 39,000 km
  • Connections: Southeast Asia, Middle East and Western Europe.

SMW-3 fiber optic cable line is a telecommunications underground fiber optic cable system that was put into use in September 1999 and completed at the end of 2000. Built by France Telecom and China Telecom, managed by Sing Tel, SMW- 3 is the only fiber optic cable route going in the direction of connecting from Asia to India, into Europe, the remaining routes all go in the direction to America via Guam and Hawaii. SMW-3 is currently the world’s longest fiber optic cable, connecting the Internet between Southeast Asia, the Middle East and Western Europe.

The optical fiber route using optical wavelength coupling technology has a system capacity of 320Gbps connecting Vietnam with 39 countries around the world. In Vietnam, this undersea fiber optic cable does land in Da Nang.

4. Lien A optical cable TGN – IA

  • Capacity: 320 Gbp/s
  • Length: 6,700 Km
  • Connections: Singapore, Vietnam, Philippines, Hong Kong.

Lien A optical cable route TGN – IA (full name is Tata TGN-Intra Asia). Put into use in early 2009, with a total length of 6,700 Km, connecting Singapore, Vietnam, Philippines, Hong Kong. In Vietnam, docked in Vung Tau.

The system has a design data transfer rate of up to 3.84Tbps, with a total initial investment of $200 million and provides an initial end-to-end capacity of 320Gbps. Lien A’s undersea fiber optic cable system is considered as an important fiber optic route to transit traffic to the Americas and Europe for customers in Vietnam and the region.

5. AAE-1 . Fiber Optic Route

  • Capacity: 40Tbps
  • Length: 23,000 km
  • Connections: Hong Kong, Vietnam, Cambodia, Thailand, Malaysia, Singapore, Myanmar, Pakistan, India, Oman, UAE, Qatar, Yemen, Saudi Arabia, Djibouti, Egypt, Greece, Italy, France.

AAE-1 optical cable route (full name is Asia Africa Europe-1) is the first undersea cable system connecting all regions of Asia, the Middle East, Africa, and Europe with the lowest connection latency between these areas. AAE-1 is connected at the world’s largest data centers such as in Hong Kong (Telecom House), Singapore (Equinix and Global Switch), France (Interxion Marseille – MRS1 and MRS2).

With a length of 23,000Km and branching points, the system lands in Hong Kong, Vietnam, Cambodia, Thailand, Malaysia, Singapore, Myanmar, Pakistan, India, Oman, UAE, Qatar, Yemen, Saudi Arabia, Djibouti, Egypt, Greece, Italy, France.

AAE-1 uses DWDM (100G/1 wavelength) high-density wavelength multiplexing technology with a design capacity of at least 40Tbps (equivalent to 80 100G wavelengths) and can be upgraded to wavelength multiplexing technologies. latest in the future.

The total investment capital of the project is about 820 million USD, in Vietnam, Viettel and VNPT are the two enterprises that participate in investing to use the capacity of this cable line, while FPT Telecom only participates in renting the capacity of the line.

The AAE-1 cable route also connects from Vietnam to the world, but in a different direction than the APG, AAG or IA routes while AAE-1 connects from Vietnam through Malaysia, Singapore, India, Pakistan, Egypt, In Europe and Africa, APG, AAG and AI connect from Vietnam through Hong Kong, Taiwan, the Philippines to the US. Therefore, even if the APG, AAG or IA undersea cable is paralyzed like the earthquake in Taiwan a few years ago, AAE-1 can still operate normally.

6. TVH optical cable route (Thailand-Vietnam-Hong Kong)

  • Capacity: 565 Mbit/s
  • Length: 3,367 km
  • Connections: Hong Kong, Vietnam, Thailand.

TVH optical cable route is an optical cable connecting Vietnam with Thailand and Hong Kong, with a capacity of 560Mb/s in each direction, put into operation in November 1995 and has a shore landing system in Vung Tau. Currently, this cable route is being managed by VNPT.

The TVH route in March 2007 was stolen 11 km of cable and some accompanying equipment in the waters of Ca Mau. The break of the TVH cable at that time had an extremely serious impact on the international Internet signal transmission with Vietnam because it had to depend on the only remaining SMW3 line. The sad thing is that this 11 km of fiber optic cable (about 100 tons, worth about 6.8 million USD) was later found to be sold for scrap.
