Latvia s fiber optic cables

Latvia has a robust fiber optic network, with nationwide FTTH coverage for over 70% of households and critical undersea links connecting to Sweden, complemented by middle-mile networks in rural areas.

Domestic Fiber Infrastructure

Latvia's primary fiber optic network is operated by Tet, which has deployed a Fibre to the Home (FTTH) network covering more than 530,000 households, approximately 72% of the country . The network spans over 13,400 kilometers and supports speeds up to 10 Gbps in select areas, a tenfold increase over previous commercial offerings . Tet's core network handles around 60% of Latvia's total internet traffic, serving as the backbone for both personal and business connectivity . The network also supports future 5G infrastructure, as every 5G tower will be connected via fiber . In addition, the Latvian State Radio and Television Center (LVRTC) has built a middle-mile optical network to improve broadband access in rural areas, particularly in regions where private operators did not plan infrastructure due to low population density . This network covers 312 “white” territories, connecting approximately 136,600 households, as well as schools, libraries, and municipal administrations . The project ensures minimum broadband speeds of 30 Mbit/s, aligning with EU digital objectives .

International Undersea Connectivity

Latvia is connected internationally through undersea fiber optic cables, including a key link between Ventspils and Gotland, Sweden, operated by LVRTC . On January 26, 2026, this cable was significantly damaged, likely due to external impact, prompting investigations involving Latvian authorities, Sweden, and NATO allies . Despite the damage, LVRTC maintained services via alternative routes, minimizing disruption to end users, though some slower data transmission occurred . The incident highlights the strategic importance and vulnerability of undersea fiber infrastructure in the Baltic Sea region .

Strategic Importance and Future Developments

Latvia's fiber optic investments aim to reduce the digital divide, particularly in rural areas, and provide high-speed, reliable internet for both residential and commercial users . The networks are privately funded and designed to support future technologies, including ultra-fast broadband and 5G connectivity . Lessons from domestic deployment are also being applied internationally, as Tet's subsidiary, Citrus Solutions, is using its expertise to deploy optical networks in Germany . Overall, Latvia's fiber optic infrastructure combines extensive domestic coverage, rural connectivity projects, and international undersea links, positioning the country as a leader in Baltic digital connectivity while highlighting the need for ongoing protection and maintenance of critical undersea cables .
