en.Wedoany.com Reported - Eurasian network service provider RETN has announced the addition of a new fiber optic line to its European backbone network, connecting Kaunas, Lithuania, with Białystok, Poland, via Suwałki. This expansion aims to enhance route diversity and network redundancy between the Baltic region and Central Europe.
The new line links Kaunas, a major Baltic traffic hub, to Białystok, a key access point to the backbone networks of Warsaw and Western Europe. Passing through Suwałki, the route utilizes one of the most important land border crossings between Lithuania and Poland, making this connection a strategic gateway between Baltic networks and the core EU network.

The Kaunas-Suwałki-Białystok axis is part of the Via Baltica corridor, where transport and telecommunications infrastructure is concentrated along limited routes. RETN emphasizes that, in this context, adding a physically independent fiber connection is crucial for improving traffic resilience and reliability along the Baltic-Central Europe axis.
RETN notes that demand for the new line is primarily driven by an increase in cloud connections, support for hyperscale cloud providers, and the intensification of east-west traffic between regional nodes and Western European backbone networks. The line aligns with the overall strategy for Nordic-Baltic infrastructure expansion, increasing the number of physical redundancy options on critical segments. Amy Bajer, Managing Director for Poland and Central Eastern Europe at RETN, stated in a press release that the Kaunas-Białystok route via Suwałki strengthens Poland's role as a key cross-border internet traffic node, and for Polish operators, it means a more reliable and flexible way to transmit data between the Baltic region and Western Europe.
