DCH Telecom's North-South backbone development plan is in the process of completing the implementation license as well as starting the first steps in preparation to ensure a safe and stable transmission network for all other projects of DCH Group..
PHASE 1
This network consists of a system of many network nodes located at 20kV/500kV transformer stations of the power company connected via OPGW optical fiber on the power transmission line, Deploying buried or leased optical fiber cables along the North-South expressway and to the provinces. Along with the development of the Leased Channel system, DCH TELECOM Company will build the main RING transmission network (with a capacity of 40Gbps) into a backbone network connecting Hanoi, Da Nang and Ho Chi Minh City.
PHASE 2
Continue to deploy phase 2 according to the planned DCH transmission network diagram, Deploy additional backup transmission lines on the 220kV/500kV line and buried cables according to the progress of the investment phases. During this phase, DCH TELECOM Company will invest heavily in the inter-provincial optical cable system along the North-South expressway axis to provide closed-loop services. The closed-loop connection will increase the network's redundancy capacity, thereby ensuring the stability and availability of the service with a total cable length of 1,160 km.
GIAI ĐOẠN 3
During this period, DCH TELECOM continues to invest heavily to complete the buried cable system along the North-South expressway axis with a total length of nearly 3,000 km to provide closed-loop services. The closed-loop connection will increase the network's redundancy, thereby ensuring the stability and availability of services, ... In parallel with the installation of new equipment, DCH TELECOM will invest heavily in inter-provincial optical cable lines to connect newly formed level 2 POPs to form a nationwide Ring network to ensure the provision of full services to customers.
It is expected that after completing the cable lines, DCH TELECOM Company will upgrade the entire domestic transmission line as follows:
- The Northern optical cable line to Huu Nghi Border Gate - Lang Son has a capacity of 10Gbps.
- The Hanoi - Da Nang optical cable line will have a capacity of 40Gbps.
- The Danang – Ho Chi Minh City fiber optic cable line will have a capacity of 40Gbps.
- The Southern optical cable line to Moc Bai - Tay Ninh border gate has a capacity of 10Gbps.
Thus, after completion, the DCH Telecom transmission network is upgraded to a total capacity of 32 Tbps, with a North-South backup of 1+2, connecting to the border fiber optic cable stations of Tan Thanh - Lang Son, Chau Doc - An Giang, Moc Bai - Tay Ninh, the AAG, IA, AAE1, APG submarine cable landing stations with 1+1 protection - all combined to create a solid infrastructure foundation for domestic and international transmission connections.
