The VNHKC cable system will be a state of the art Dense Wavelength Division Multiplexing (DWDM) fibre optic network spanning approximately 1050 Km, connecting Da Nang in Vietnam and Hong Kong SAR. The system will consist of three main segments, together forming a high capacity point to point network.
Segment S is the submerged fibre optic cable together with repeaters and branching units as well as the land based DWDM system and power feed equipment. The cable will contain four fibre pairs, each fibre pair capable of carrying sixty-four channels at 10 Gbit/s giving the system an ultimate design capacity of 2,56 Terabit/s.
Segment S will terminate in existing landing stations using existing landing points, this will ensure a very cost efficient solution as well as minimizing the environmental impact. This also means that the system on Ready For Service date will have easy access to directly interconnect to a number of different cable systems for onward capacity beyond Hong Kong to the rest of the world as well as offering efficient restoration possibilities.

Segment T1 andT2 are the terrestrial portions in Da Nang and Hong Kong respectively these segments consists of the transport equipment between the landing station and the POP as well as the service delivery platforms in both CLS and POP.
The terrestrial transport network is diversely routed DWDM systems capable of transporting 10 Gbit/s wavelengths.

On Ready For Service date the VNHKC system will be able to deliver services from E1 up to STM-64 from POP in Hong Hong to POP in Da Nang and vice versa, as well as 2.5 and 10 Gbit/s wavelengths. Future services will also include Ethernet services.
The main Network Operations Centre will be located in Vietnam with a 24/7 backup NOC outside of Vietnam.
