ISOIEC11801

ISO/IEC 11801 is a widely used international standard for information technology (IT) cabling and infrastructure. It provides a comprehensive set of requirements and guidelines for designing, implementing, and testing structured cabling systems.

The standard was first published in 1995 by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC). It has undergone several revisions since then, with the most recent version being published in 2017. The standard applies to all types of cabling systems, including Category 5e, Category 6, and Category 7, and covers all aspects of cabling infrastructure, from performance and security to electromagnetic compatibility and distance requirements.

ISO/IEC 11801 specifies the following key aspects of cabling infrastructure:

* Performance requirements: defines the minimum transmission performance requirements for each category of cable

* Cable characteristics: specifies the physical and electrical properties of cables, including conductor resistance, capacitive reactance, and insulation resistance

* Termination and connection: provides guidelines for connecting cables to equipment and other components

* Cable routing and layout: offers recommendations for cabling pathways, including routing, depth, and bend radius

* Testing and verification: outlines the testing and verification procedures to ensure compliance with the standard.

The standard is widely adopted and recognized around the world, and its requirements are often used as a reference for the development of national and industry-specific standards. It is used in a wide range of applications, from commercial buildings to data centers and telecommunications networks.
