Standards and Basic Principles of Network Technology

Structure and Configuration

The EN50173 standard specifies the structure and configuration of primary, secondary and tertiary sub-systems of the cabling of a telecommunication cabling system.

EN 50173: Information Technology - Generic Cabling Systems

Part 1: General requirements

Part 2: Office premises

Part 3: Industrial premises

Part 4: Home

Part 5: Data centres

Part 6: Distributed building services


The following standards apply to the installation of generic structured cabling systems:

In practice, the most important standards concerning the assembly of structured cabling systems are EN 50174 and EN 50346. They describe the issues which need to be taken into account when installing and testing a structured cabling system.

EN 50174: Information technology - Cabling installation

Part 1: Specification and Quality Assurance

Part 2: Installation planning and practices inside buildings

Part 3: Installation planning and practices outside buildings


EN 50346: Information technology - Cabling installation - Testing of installed cabling


EMC, Potential Equalisation and Earthing

Issues such as EMC, potential equalisation and earthing are gaining in importance with ever larger limit frequencies. The relevant standards are:

EN 50310: Application of equipotential bonding and earthing in buildings with information technology equipment.

EN 55022: Information technology equipment - Radio disturbance characteristics - Limits and methods of measurement

EN 61000: Electromagnetic compatibility (EMC)

Part 6-1: Generic immunity standards - Residential, commercial and light industry

Part 6-2: Generic immunity standards - Industrial applications

Part 6-3: Generic emission standards - Residential, commercial and light industry

Part 6-4: Generic emission standards - Industrial applications
