Optical distribution board with fibre termination using connectors
Explanation of obligations

Optical infrastructure in buildings according to GIA standards

Regulation (EU) 2024/1309 on measures to reduce the costs of building gigabit networks. A summary of what it means for builders: no legal jargon, with links to the source.

The Regulation replaces the older Directive 2014/61/EU, which was implemented in the Czech Republic by Act No. 194/2017 Coll. The key difference is that the Regulation is directly applicable. There is no waiting for a Czech implementing provision and obligations fall on builders automatically.

Appointments

12. 11. 2025

General applicability of the regulation

The regulation becomes applicable in its entirety. Member States were required to adopt technical standards for internal infrastructure by this date.

12. 2. 2026

Obligations in buildings (Art. 10)

Key date for builders. Applies to buildings where the building permit application was submitted after this date.

12. 5. 2026

Single information point

Digitalisation of single information points is underway under Articles 4, 6, 7 and 12, mainly concerning access to data on existing infrastructure.

What the building must have

According to Article 10, paragraphs 1 to 3

Physical infrastructure ready for optical fibre

Protective sleeves, microtubes, penetrations, shafts and distribution cabinets, i.e. The elements into which the cable is laid, including the building entry point.

Optical cabling inside the building

Routing to the point where the end user connects to the public network. It is not just a prepared pipe, but the fibre itself.

Access point

In multi-unit buildings, a physical point accessible to operators where the public network connects to the building’s internal infrastructure.

Who is responsible for

Novostavby

No restriction on intended use. The older directive was narrower; the regulation refers to buildings in general.

Extensive refurbishments

Including structural changes to the entire indoor physical infrastructure or a significant part of it, if they require building permission.

The date of application is decisive.

The decisive factor is the submission of the building permit application after 12. 2. 2026, not the start of construction or completion approval.

Technical requirements

Specific parameters are defined by technical specifications adopted at national level. In the Czech Republic, a revision of CSN 34 2300 is being prepared; designers have reference material in the CKAIT technical aids series TP 1.25.

Exceptions and markings

Exceptions

The regulation allows for the exclusion of building categories where compliance would be disproportionately costly, as well as special categories such as heritage-listed and historic buildings, military facilities, and national security structures. Any exemption must be properly justified and proportionate.

Fibre-ready designation

According to Article 10, paragraph 6, a building equipped in accordance with this article is eligible for the ’ready for optical fibre’ label. This is voluntary and procedures are set by Member States.

Sankce

Article 15 requires Member States to establish sanctions that are effective, proportionate and dissuasive. The specific amount is a matter of national regulation.
