DELSKA
In Lithuania, Delska owns and operates a dark fibre optical network, giving customers direct access to higher bandwidth capacity, lower latency, and additional layers of resilience. To enable long-distance, high-volume data transmission, the company deploys DWDM( Dense Wavelength Division Multiplexing), which increases cost-efficiency while delivering scalable bandwidth.
This is complemented by a secure, redundant Layer 2( L2) Ethernet network that supports multi-route connectivity with flexible bandwidth options of 1G, 10G and 100G between PoPs.
For businesses requiring global reach, Delska also provides IP transit services with speeds of up to 100G, leveraging Tier 1 backbone providers at every PoP. This ensures businesses can reliably connect with their users worldwide. Seamless links to major Internet Exchange points further guarantee fast, direct access to leading cloud providers.
Beyond connectivity, security investment addresses cyber threats and regulatory requirements. The NIS2 directive mandates enhanced security measures for critical infrastructure operators, driving investment in protection systems.
“ To meet the evolving needs of IoT, public cloud, AI and other advanced technologies, we are making significant investments in internet capacity, DDoS mitigation and strengthening our cybersecurity framework in line with ISO standards and the forthcoming NIS2 directive,” says Viktoras.
This network foundation supports customer expansion across regions while bringing data closer to end users, accelerating performance, reducing latency, and ensuring high-capacity connectivity from the Baltic region to data exchange hubs in Warsaw, Berlin, Frankfurt, Amsterdam, Stockholm, Helsinki, and extending even further via last-mile connectivity through local and international partners.
