Neterra launches the biggest capacity fiber optic network for data transfer between Europe and the Middle East

  • The network will provide up to 800 Gps of bandwidth and will be the first in Bulgaria of this capacity
  • This network has the capability to "selfpreserve", i.e. to ensure uninterrupted connection inside Bulgaria as well as to neighbour countries.
  • The Neterra network provides capacities both within Bulgaria and the countries of South-East Europe.


800 Gbps is the projected capacity of the DWDM (Dense Wavelength Division Multiplexing) network, which was going to be launched in June by the leading Bulgarian telecom operator Neterra. This capacity makes it the largest capacity fiber optic network for data transfer from Europe to Turkey. Its reliability and security are due to its ring structure, as well as to the numerous interconnections to other operators in Europe.

DWDM networks are next generation networks and have the capability of secure and quick transfer of large capacities of data, and in addition they are highly effective in long distance transfer, with no quality compromises. Another major advantage of DWDM technology is that it is protocol and bit- rate independent. Thus DWDM-based networks can carry different types of traffic at different speeds over an optical channel. It is expected that DWDM will be a basic technology for all fiber optic networks in the future.

"We were among the few telecommunication operators, who were to realize the great opportunities for development the Turkish market and the markets of other Balkan countries offer. For this purpose we aimed our efforts in putting into effect this network, that utilizes data transfer through secured channels, from Eastern Europe to the Balkans, Turkey and the Middle East" - said Neven Dilkov, Managing Director of Neterra. "In fact, excluding the networks that have already been built, crossing the bottom of the Mediterranean Sea, Bulgaria is the only point through which connection between Europe and Middle East can be achieved" - he added.
For the technical implementation of the network Neterra opened a tender for supplier of equipment in March, 2008. Eight leading manufacturers of telecom equipment applied. The tender was won by Nokia Siemens Networks.

"We are glad to be able to support Neterra with the most advanced transport solutions. The installation of this optical backbone network is further evidence of Nokia Siemens Networks' leadership in providing solutions that facilitate the provision of services that capture the rapidly growing data traffic and help businesses and communities across the world stay online," said Guenter Haberler, Head of Customer Team IFP of Nokia Siemens Networks.
