ATMAN network expansion: Frankfurt, Silesia, nationwide network and metropolitan area networks

ATM S.A., which provides communications services under ATMAN brand, is expanding its nationwide data network as specified in its investment plans released earlier. The objective of the expansion is to meet the needs of the data service market and the growing requirements of carriers who expect higher and higher communications services throughput rates.

The first cross-border node of the ATMAN backbone, located in Frankfurt, will be expanded in the near future. The existing 2.5 Gbps links will be replaced with 10 Gigabit Ethernet links.

The final expansion stage involved expanding metropolitan area networks (MANs) in Silesia — the cities of Sosnowiec and Będzin were added to the ATMAN infrastructure.

Additionally, the implementation of 10 Gigabit Ethernet nodes was completed in the northern ring of the nationwide network, which covers Warsaw, Poznań, Szczecin, Koszalin and Gdańsk.

The investments are the result of very fast growth of Internet traffic in the ATMAN backbone. This is another step in the upgrade of the nationwide network and MANs, that has been carried out since 2007. With the activation of DWDM nodes with data rates up to 160 Gbps and 10 Gigabit Ethernet technology, the ATMAN backbone can not only support its existing customers, but can also handle the fast increase in IP traffic volumes that is expected when new applications, such as Internet TV, become more widespread.

Fiber-optic metropolitan area networks are being expanded along with the nationwide backbone upgrade. To summarize, the length of fiber optic links increased by more than 150% in 2007. There is now more than 25,000 kilometers of fiber optics in operation, which amounts to more than 170% growth (data from late 2007, not including long-distance links).
