OREANDA-NEWS. January 14, 2014. Kazakhtelecom JSC innovational sub-division realized a project on launching to commercial exploitation of 100Gbit/s channel  without regeneration on existing DWDM main network (at one of loaded sites of 500 km) for external internet traffic needs and inter operators transit was realized for the first time on territory of Republic of Kazakhstan and Central Asia.

In 2013 Kazakhtelecom JSC innovational sub-division worked out a project on increasing bandwidth of main optical transport DWDM network. Project was realized for satisfying needs to pass line for company’s subscribers and international transit services. At present constant growth of data transfer traffic volumes is observed (fixed and mobile broadband access to internet, data transfer services, inter operators transit), respectively, capital and operational costs of telecom operators are growing. This project will allow reducing capital and operational costs at expense of introduction of innovation technologies and simplified architecture of network infrastructure.

Channel launch of 100Gbit/s became possible thanks to implementing several technological innovations. The project was realized on base of optical transfer equipment of spectrum density of DWDM with applying coherent technology for optical signal processing and dispersion compensators at Bragg grates. In result, 100Gbit /s channel launched without organization of optical signal regeneration centers on its site. Lack of regeneration centers allowed gradually optimizing capital costs to channel organization and minimizing network delays at this site.

In the future Kazakhtelecom JSC plans to continue work on development and optimization of optical transport DWDM network on base of 100Gbit /s channels. Today company realizes a project on organization of 100Gbit /s channel on west site.

Implementing of such innovations to network infrastructure meets market needs by traffic volumes and secures economical and financial company’s efficiency.
