Establish DWDM backbone transmission network .

Enhance the IP backbone network  

Network Connectivity for 2,600 unions by deploying optical fiber.

Provide power system (rectifier) forupazillas and unions.

The 'nfo-Sarker Phase III is the supplementary project of Phase I and Phase II. The whole network is based on the ring-shape structure of DWDM tranemission network. The top leyel is the national backbone node at Dhaka, follov-ed with vertical administrative levels, up to unions. The whole project can provide high-efficient service for all divisions, districts, upazillas and unions while facilitating the network management. The optical transmission would be deplc fed to fulfill the bandwidth needs of distance learning and other e-qovernment services.
 

DWDM backbone transmission network construction

By adopting DWDM technology, a single optical fiber can carry higher bandwidth capacity. This not only resolves the current problem of insufficient bandwidth and fibers, it will also meet the requirement of the long-term development in the future. DWDM technology for metropolitan broadband network can solve the problem of insufficient bandwidth and fibers while providing higher quality of service delivery. In order to save valuable fiber resources, and to meet the bandwidth requirement, the high-end DWDM equipment with 100G capacity would be deployed in the sadar upazilla nodes. One 100G channel would be needed from every sadar upazilla node to the core node with OlP protection. All of the 100G channel would be dropped in the core node of NTTN, and NTTN shall carry out necessary expansion of the core nodes to integrate the expanded DWDM network. The medium DWDM devices with 10G technology would be deployed in the upazilla nodes. One 10G channel would be needed from every upazilla node to the sadar upazilla node with 1+1 protection.

IP backbone network expansion

To fulfill the increasing bandwidth needs and get better experience, the existing backbone network expansion Lipto upazilla is essential.
