With seven years of operation in the telecommunications sector, CMC Telecom is currently one of the ISPs with 100% fiber optic infrastructure, having a backup for the intra-Asian cable system (IACS) that connects Singapore, Vietnam, the Philippines and Hong Kong. CMC Telecom is also the direct owner of more than 18,500 kilometers of fiber optic in Hanoi, HCMC and Danang with a north-south backbone network capable of providing a speed of up to 10Gbps. In addition, the ISP is cooperating and sharing infrastructure with its major partners in telecommunications, security and television across the country.

As submarine cable systems like AAG, Vietnam-Cambodia and Vietnam-China Unicom are now always at risk of disruption, CMC Telecom has actively invested in an inland cable system called CSC and considers this as its main system with a capacity of up to 2,5Gb/s connecting China, Vietnam, Laos, Thailand, Malaysia and Singapore. This has been helping CMC Telecom over the past time and will also be in the future, ensuring stability and preventing a decline in Internet connection when unwanted incidents occur.
