What is BS EN50173?

The BS EN50173 standard, also known as the Structured Cabling Standard for Information Technology, is a set of guidelines and requirements used in the design and implementation of network infrastructure. It specifies the performance characteristics and cabling requirements for various electronic communication systems.

The Importance of BS EN50173

BS EN50173 plays a crucial role in ensuring the reliability, scalability, and performance of network installations. By adhering to this standard, organizations can ensure seamless connectivity, robust data transfer, and efficient operations for their IT networks.

One of the key benefits of following the BS EN50173 standard is its compatibility with different types of communication devices and equipment. This allows for flexibility and interoperability, enabling organizations to easily upgrade or expand their networks without major disruptions or costly replacements.

Key Components of BS EN50173

The BS EN50173 standard primarily focuses on four main components:

Cabling Infrastructure: The standard outlines the specifications for structured cabling systems, including the types of cables, connectors, and patch panels to be used. It also provides guidelines for cable management and labeling.

Performance Requirements: BS EN50173 defines the performance parameters that cabling systems should meet, such as bandwidth, crosstalk, attenuation, and return loss. These parameters ensure high-quality data transmission and minimize signal interference.

Testing and Certification: To ensure compliance, the standard requires rigorous testing of cabling installations. This includes conducting tests for cable length, insertion loss, impedance, and near-end crosstalk. Certifications are issued based on the results of these tests.

Documentation: BS EN50173 emphasizes the importance of documentation in maintaining and managing cabling infrastructure. It includes requirements for creating records of network design, installation plans, test results, and maintenance procedures.


In today's fast-paced and data-driven world, maintaining a high-performance network infrastructure is crucial for businesses of all sizes. Adhering to the BS EN50173 standard ensures that organizations have a reliable and efficient cabling system in place, capable of supporting their communication needs both now and in the future.
