What Unsere Grüne Glasfaser does

Unsere Grüne Glasfaser (UGG) is a German fiber-optic infrastructure operator founded in 2020 as a 50/50 joint venture between Allianz and Telefónica Group, headquartered in Ismaning near Munich. UGG builds and operates a wholesale, provider-neutral (anbieterneutral) Fiber-To-The-Home (FTTH) network under an open-access model, selling capacity to multiple internet service providers (ISPs) including O2, Amiva, LEONET, Stiegeler, Thüringer Netkom, empera, Eifel-DSL, teranet, and Breitbandversorgung Deutschland. The company targets German municipalities and underserved rural and suburban regions, deploying fiber directly to single-family homes (Einfamilienhäuser) and multi-family buildings (Mehrfamilienhäuser) via Gestattungserklärung and VGM agreements, and extends its infrastructure to enterprise telecom customers through Fibre-to-the-Site (FTTS) backhaul for mobile network sites.

UGG's technical stack consists of pure-play FTTH architecture, including Point-of-Presence (PoP) distribution, Hausübergabepunkt (HÜP), Optical Network Termination (ONT), and Glasfaser-Teilnehmeranschlussdose (Gf-TA) at the customer premises. The company emphasizes energy efficiency (approximately 60% lower power consumption than legacy copper), 1,000 Mbit/s symmetric speeds, and sub-10 ms latency as functional benefits. It is one of a limited number of German fiber operators offering specialized multi-dwelling unit (MDU) services for the Wohnungswirtschaft (housing industry).

The business model combines (i) one-time house-connection fees from property owners (€0 per residential unit for multi-family buildings if an ISP contract is signed, €150 net / €178.50 gross otherwise; custom quotes for connections over 30 meters), (ii) recurring wholesale revenue from ISP partners selling retail internet services over the network (typical ISP tariffs €30-40/month), (iii) enterprise FTTS contracts with mobile network operators, and (iv) acquired ISP subsidiaries (LEONET and Breitbandversorgung Deutschland, via the December 2024 acquisition of Infrafibre Germany GmbH) that retail directly. As of late 2024, UGG had secured €1.65 billion in committed financing from its parent companies and targeted coverage of 2.2 million households, making it one of Germany's largest FTTH providers despite still being in an active buildout phase.

Revenue model

1. Fiber-to-the-Home Connection Fees (Hausanschluss): UGG charges property owners for fiber optic house connections. For Mehrfamilienhäuser (multi-family buildings), the fee is €0 net (€0 gross) per residential unit if a resident signs an internet service contract with an ISP partner. If no ISP contract is signed, a fee of €150 net (€178.50 gross) per residential unit applies. For connections exceeding 30 meters from property boundary to building, individual pricing quotes are provided. The company also builds fiber networks during a rollout phase where connections are typically free for customers who sign up during that window.
2. Open-Access Network Infrastructure: UGG generates revenue by providing wholesale fiber infrastructure to multiple internet service providers (ISPs) who resell internet services to end consumers. ISPs include O2/o2, Amiva, LEONET, Breitbandversorgung Deutschland, empera, Eifel-DSL, Stiegeler, Thüringer Netkom, and teranet. The open-access model allows UGG to monetize the same physical network infrastructure through multiple ISP partners simultaneously.
3. Infrastructure Acquisition & Integration: UGG acquires fiber network operators (e.g., Infrafibre Germany GmbH) and their ISP subsidiaries to expand its addressable market. Through the acquisition of IFG including LEONET and Breitbandversorgung Deutschland, UGG aims to serve 2.2 million households, combining network ownership with retail ISP capabilities.
4. FTTS (Fibre-to-the-Site) Enterprise Contracts: UGG provides dedicated fiber connections to mobile network tower sites (FTTS) for telecommunications companies. Telefónica Deutschland entered a nationwide framework agreement with UGG to connect its mobile network sites to fiber-optic infrastructure. This B2B revenue stream serves telecom infrastructure needs.

Product overview

Unsere Grüne Glasfaser (UGG) operates a neutral, open-access, wholesale fiber-to-the-home (FTTH) infrastructure platform.
