Polski Swiatlowod Otwarty

What Polski Swiatlowod Otwarty does

Polski Światłowód Otwarty (PŚO) is a Polish wholesale fiber-to-the-home (FTTH) network operator that provides open access connectivity to retail ISPs and telecom operators across all 16 Polish voivodeships. The company operates a GPON-based fiber network covering approximately 5.2 million households as of January 2025, with a stated target of more than 6 million households, and offers products including 8 Gb/s wholesale service priced at the 1 Gb/s tier, with over 50% of installations completed within three days. PSO does not serve end consumers directly; instead, it monetizes the network through recurring wholesale subscription contracts with retail operators including Play, T-Mobile, Plus, Orange, Netia, Vectra, RFC, Flashnet, AirNet, and Optikabel, supported by API and customer portal order-management integration.

The company's commercial model is the open access wholesale model mandated in EU-funded FTTH deployments: any qualified retail operator can use the network on equal, non-discriminatory terms, and 74% of PSO's coverage is priced below most Polish operators' wholesale offers. PSO owns and operates the network through a group of wholly-owned subsidiaries — including PT Sp. z o.o., SferaNET Infrastruktura S.A., MicoInfra Sp. z o.o., Media-Sys Sp. z o.o. (POPC-funded Tarnobrzeski network), PŚO Infra I S.A. (formerly Voice Net), MGK Fiber Sp. z o.o., and Elsat Sp. z o.o. — several of which were acquired or merged in 2025–2026 as part of an aggressive consolidation strategy.

PSO is privately held and financially backed by Play Group, the Polish telecom conglomerate, which underwrites its acquisition-led expansion. Recent completed transactions include the approximately 200 million PLN acquisition of Voice Net (March 2026, adding over 176,000 households), the acquisition of Elsat (June 2025), a merger with MicoInfra (July 2025), and prior takeovers of Media-Sys and portions of Vectra's infrastructure. CEO Ignacio Irurita leads the company, which has 51–100 employees and is headquartered in Warsaw with network operations extending across Poland. No standalone audited PSO revenue has been disclosed in the input data.

Direct peers

• Fiberhost: Polish wholesale open-access fiber operator (subsidiary of Grupa Polsat Plus) operating a comparable national FTTH network sold on non-discriminatory terms to retail ISPs. Closest domestic direct competitor and named acquisition candidate for PSO.
• Inea: Regional fiber operator in Greater Poland (Macquarie-owned), combining retail and wholesale fiber. Comparable open-access-style fiber footprint and identified publicly as a PSO acquisition target.
• Deutsche Glasfaser: Germany's leading open-access FTTH wholesaler (EQT / Liberty Global-backed), operating a comparable nationwide wholesale fiber footprint sold to retail ISPs. International benchmark for PSO's model.
• HAWE Telekom: Polish fiber infrastructure operator providing wholesale backbone and access services. Comparable wholesale fiber operator active in the Polish market with overlapping customer segments.
• CityFibre: UK-based wholesale open-access fiber operator with a multi-million-home FTTH footprint sold to retail ISPs on equal terms. Closest international structural comparable to PSO's wholesale-only open-access model.

Broad incumbents

• Vectra: Polish cable and fiber operator, simultaneously a PSO wholesale customer and seller of fiber infrastructure to PSO. Comparable hybrid cable/fiber footprint with retail and wholesale exposure.
• Netia: Integrated Polish telecom (part of Polsat Plus Group) operating both retail and wholesale fiber services. Comparable business model spanning wholesale access and enterprise/retail customers.
• Orange Polska: Poland's largest incumbent telecom with its own nationwide FTTH network. Acts as both a PSO wholesale customer and a vertically integrated competitor with overlapping retail broadband offerings.
• T-Mobile Poland: Major Polish MNO and PSO wholesale customer, part of Deutsche Telekom. Pursuing FTTH convergence strategy that creates both partnership demand and competitive overlap with PSO's footprint.
• Polkomtel (Plus): Major Polish MNO and PSO wholesale customer (via Grupa Polsat Plus, which also owns Netia and Fiberhost). Competes in fixed-mobile convergence while depending on wholesale fiber access from PSO and its own Fiberhost.
