STOCKHOLM--Ericsson today announced they have signed a contract to supply the major part of an optical trunk DWDM networking solution to Sonera, Finland. Their ERION solution will be used to enhance the optical highway between Central Europe - Copenhagen - Stockholm - Helsinki and on to Moscow. Total length of the network will be over 7.500 kilometers.

The already existing optical cables have reached its limits in capacity and will now be boosted by deploying the latest optical technology by Ericsson. The ERION Linear DWDM system, designed to carry 10Gbps in each separate wavelength, will be used along the route.

With this new optical highway, several different traffic types are multiplexed into combined high traffic volumes and carried over the network with its own individual optical wavelengths. The network is designed to carry 320Gbps on each pair of fibers. Sonera was the first operator to select Ericsson as its vendor already four years ago, when the first products were released to the market. The ERION product portfolio reduces the operators' investment, improves overall network efficiency and cuts operating costs, for any traffic application.
