APG submarine cable has a problem, what does the network operator do to minimize the impact on users?

According to information from VNPT and Viettel, at noon on April 15, Asia Pacific Gateway (APG) international undersea fiber optic cable had a problem on segment S1.7, about 910 km from the Singapore landing station of the cable line. The preliminary cause was determined by the management unit of the APG submarine cable route to be a broken fiber on segment S1.7.

A new incident occurred with the APG undersea cable, causing disruption of all international Internet connection services on the cable route.

Because they are used to dealing with situations where undersea cables have problems, this time Internet service providers (ISPs) in Vietnam also quickly implemented plans to minimize the impact on service users.

Specifically, a representative of Viettel said that the network operator always plans, routes and allocates capacity on international cable routes to ensure the best quality of service provided to customers.

The problem of loss of capacity on the APG cable line is in Viettel’s backup scenario. When an incident occurred, the traffic was automatically and optimally routed, divided during peak hours through other undersea cable routes such as TGN-IA; AAE-1, AAG and land cable for international connection. Therefore, the incident APG encountered this time has not affected the service quality of customers using Viettel network.

Also to minimize the impact and ensure the quality of services provided to customers, VNPT has a plan to switch international traffic to another cable direction. Similarly, immediately after the incident, CMC Telecom transferred traffic to AAE-1, AAG and land cable lines.

Representatives of the network operators said that they will continue to work with the Management Board and operate the APG undersea cable line to have continuous updates on the plan to repair problems on the S1.7 branch of the cable line.

Officially put into operation in mid-December 2016, the APG international undersea optical cable has a length of about 10,400 km, APG is located underground in the Pacific Ocean. The cable route has connection points in China, Hong Kong (China), Taiwan (China), Japan, Korea, Malaysia, Singapore, Thailand and Vietnam. APG undersea cable has the participation of investment from Vietnamese carriers VNPT, Viettel, FPT Telecom, CMC Telecom and is considered as a cable route contributing to bringing stable transmission with larger capacity for Internet users in Vietnam. Male.

In the last year, the APG undersea fiber optic cable has had 4 problems. In the fourth time in December 2021, the APG cable had problems in 2 directions connecting the cable to Japan and Hong Kong (China). On January 14, 2022, the problem on the S1.5 branch of the APG cable connecting to Japan was fixed. And on February 27, 2022, after nearly 3 months of service interruption, the APG undersea cable was repaired and restored to normal operation.
