EN 50173 group of standards specifies:
  • The structure and configuration of the backbone cabling subsystems of generic cabling systems within the types of premises defined by the EN 50173 series of standards
  • Channel performance requirements in support of the EN 50173 series of standards
  • Link performance requirements in support of the EN 50173 series of standards
  • Backbone cabling reference implementations in support of the standards in the EN 50173 series
  • Component performance requirements in support of the standards in the EN 50173 series
The standard series of EN 50173 is divided into five areas for various applications and covers application-neutral communication cablings for information technology".
  • EN 50173-1 General requirements
  • EN 50173-2 Office buildings
  • EN 50173-3 Industrially used buildings
  • EN 50173-4 Private residential units
  • EN 50173-5 Computing centres
There is also a difference in the individual components such as cables and connection technology and also in the installation of these components.

The individual components are classified into the following categories:
  • Category 5 up to 100 MHz
  • Category 6 up to 250 MHz
  • Category 6A up to 500 MHz
  • Category 7 up to 600 MHz
  • Category 7A up to 1000 MHz
A distinction is drawn between installed components according to transmission classes:
  • Class D up to 100 MHz
  • Class E up to 250 MHz
  • Class EA up to 500 MHz
  • Class F up to 600 MHz
  • Class FA up to 1000 MHz
Certification and checking of the limiting values for the measurement technology of the installed transmission routes.

A distinction is drawn between two models for the transmission routes for the cabling.
