Fiberhost: what it is, coverage, contact, and the T-Mobile acquisition (2026)

If you live in Wielkopolska and have Fiberhost fiber delivered by Orange, Play, Inea or a local operator, there is a fair chance you are physically using the network of Fiberhost SA. The very same one that T-Mobile is about to buy.

Fiberhost is one of Poland's largest wholesale operators, the company builds fiber and leases it to others, which then sell the service to end customers. The "we lay it once, you pick your provider" model has been running in Poland for over a decade and has just entered its decisive phase: one owner is leaving, the next one is waiting in the wings.

In this guide we walk through everything worth knowing about Fiberhost in 2026, what the company is, where it has coverage, how to contact it, who sells internet on its network and why it is about to change hands.

Fiberhost (full name: Fiberhost SA, formerly INEA SA) is a wholesale fiber operator, the equivalent of companies such as Nexera, Polski Światłowodowy Operator (PŚO), Światłowód Inwestycje (ŚI Orange/APG) or Tauron Światłowód. Wholesalers do not sign contracts with individual customers, they build FTTH infrastructure and sell access to it to retail operators, who then deliver internet and TV services.

For the end customer this means one thing: the same fiber in your building can serve offers from 5–10 different operators. You pick the brand, someone else supplies the infrastructure, often Fiberhost. Hence the common questions: "Fiberhost Orange?", "Fiberhost Play?", "Inea Fiberhost, is it the same company?", we answer them below.

Fiberhost grew out of INEA S.A., a Poznań-based cable operator from the 1990s, whose infrastructure arm was spun off and turned into a wholesale company. In October 2018, Fiberhost became the first company in Poland to commercially launch XGS-PON (symmetrical 10 Gbps per fibre), in Poznań, on its own network.

In 2021 the company was acquired by the Australian infrastructure fund Macquarie Asset Management (through the MEIF 5 vehicle). Under Macquarie's control the firm continued to expand, mostly outside Wielkopolska (Lubelskie, Łódzkie, Mazowsze), although in 2024 it withdrew from 23 KPO competition areas and 3 FERC areas, returning around PLN 476 million in grants. The move was a response to cost cuts ahead of the planned sale.

In November 2025, Macquarie launched the formal process of selling its Polish assets, Fiberhost and its sister retail company Inea Sp. z o.o., grouped under the Luxembourg vehicle Odin Holdings S.à r.l. Valuation: around $1 billion.

Fiberhost runs two passive optical network (PON) standards in parallel:

Total length of the Fiberhost network in Poland: 42,295 km (as of 2024, steadily growing).

At TelecomRadar we maintain our own coverage database built on wholesale operator registries. We measure the same geographic footprint with a different unit than the operator itself, and it's worth clarifying that before you look at the numbers.

Two different measurements of the same coverage:

• Operator (Fiberhost SA): 1.4 million HP, Homes Passed, i.e. dwellings in apartment blocks plus single-family houses. The standard telecom metric (used by UKE, GUS and the FTTH Council Europe reports).
• Our database: 297,287 unique buildings at specific addresses across 5,525 localities. One multi-dwelling building (MDU) = ~5–25 dwellings (HP). One single-family house = 1 HP. Converted, this yields ~1.5–1.8 million HP.

The figures match on order of magnitude, they differ only in measurement methodology. The operator's end-of-2026 target (2 million HP) maps to our building base growing to roughly 400,000.

The most intuitive cut: where is Fiberhost actually present?

The Wielkopolska dominance is no accident, Fiberhost grew out of the Poznań-based INEA, and that is where its densest network is. The second pillar is Lubelskie, where Fiberhost invested as part of the POPC (Operational Programme Digital Poland), in 2026 Lubelskie holds 71,000 buildings, nearly a quarter of the operator's entire network.

The largest concentrations of Fiberhost buildings are in the following cities:

The operator's target by the end of 2026 is 2 million homes passed, with further expansion outside Wielkopolska (mainly eastern Poland).

Fiberhost has adopted a multi-fiber model, meaning that several dozen different retail operators can operate on a single building at the same time. The customer picks a brand and a plan, and the installer connects to the same fibre infrastructure.

Retail operators using Fiberhost (confirmed in 2026):

Altogether, more than 100 retail operators in Poland sell end-user internet on the Fiberhost network. This is the key element of the wholesale model, the customer is unaware that "their" operator uses another company's infrastructure, while in reality it is Fiberhost that is responsible for the throughput and stability of the connection.

Macquarie bought Fiberhost in 2021 with a plan to expand the network and then sell it to a strategic investor after a few years. Having built 1.4 million HP and cut costs (withdrawing from 26 KPO/FERC areas in 2024), the fund decided to exit.

The formal sale process:

The number of "Fiberhost phone contact" queries in Google has grown by 900% over the past year. That is more than any other growth around this brand. There is a catch though: Fiberhost does not run a hotline for retail customers, and probably never will. This follows directly from the business model (wholesale): Fiberhost's customers are other companies, not you.

If you are looking for Fiberhost's phone number, you almost certainly landed here for one of three reasons:
