Internet users in Vietnam, Cambodia, and Lao PDR should now be experiencing faster and more stable international internet services following the completion of repairs to the Asia Pacific Gateway (APG) undersea cable.

Repairs to the S9 and S1.7 branches of the cable connecting Vietnam with Singapore and Hong Kong were finally completed earlier this week after the entire system grounded to a halt on May 23. (See: Undersea cable faults cause internet chaos in Vietnam, Cambodia & Lao PDR)

FInalised two days ahead of schedule, the 10,400 kilometer (about 6,500 ml) long APG is one of the main submarine cables linking Vietnam with its neighbours in the Asean region.

Almost coinciding with the break in the APG, the 20,000 kilometer (12,500 ml) fibre optic Asia America Gateway (AAG), which carries more than 60 per cent of Vietnam’s international internet traffic, was also damaged. The combination of the two significantly impacted internet speeds across the three countries until the AAG was repaired in the first week of June.

Singapore tops for speed

Similarly, repairs were recently completed on a section of the 25,000 kilometer (15,500 ml) Asia Africa Europe 1 (AAE-1) submarine cable, which suffered a malfunction on June 3 in the S1H section linking Vietnam with Hong Kong.

According to the May 2020 Speedtest report Vietnam’s internet broadband download speed increased from 47.66 Mbps in April to 52.29 Mbps, ahead of Lao PDR (34.16 Mbps), the Philippines (22.31 Mbps), Cambodia (21.83 Mbps), Indonesia (19.79 Mbps), and Myanmar (18.00 Mbps).

All, however, lag significantly behind the 205.136 Mbps recorded in Singapore or the 170.14 Mbps in Thailand, and Malaysia’s 81.08 Mbps.

As of May internet penetration in Asean was said to have averaged 68.26 per cent, with Brunei, Singapore, and Thailand having the highest internet usage rate at 95.3 per cent, 88.4 per cent, and 81.7 per cent respectively.

On June 14 VN Express reported that a new 9,400-km (6,151 ml) submarine cable with a bandwidth of 140 Tbps, more than the total of all existing cables connected to the country, is slated for completion by 2022.

Japanese tech company NEC will lay the cable for Asia Direct Cable (ADC), which will feature multiple pairs of high capacity optical fibers providing high-capacity data transmission across East and Southeast Asia, connecting Hong Kong, China, Japan, the Philippines, Singapore, and Thailand.

The ADC Consortium is comprised of CAT, China Telecom, China Unicom, PLDT, Singtel, SoftBank, Tata Communications and Viettel.
