IEC 60794-1-3:2013 is a technical standard that specifically addresses optical fibre cables for outdoor use. It provides specifications and requirements for the design, construction, installation, and performance of these cables. This standard is applicable to all types of outdoor optical fibre cables, including those used for aerial, duct, and direct burial installations. It is essential for ensuring the reliable and efficient transmission of data over long distances.
Design and Construction Requirements
The design and construction requirements outlined in IEC 60794-1-3:2013 cover various aspects of outdoor optical fibre cables. These include the choice of materials for cable components such as core, cladding, buffer tubes, strength elements, and jackets. The standard provides guidelines for determining the dimensions, mechanical strength, and temperature capabilities of the cables. It also specifies requirements for the cable's resistance to environmental factors such as moisture, UV radiation, and chemicals that could potentially degrade its performance.
Installation Considerations
IEC 60794-1-3:2013 includes important considerations for the installation of outdoor optical fibre cables. These considerations ensure that the cables are installed correctly and protect them from damage during and after installation. The standard provides guidelines for proper cable routing, bending radius limitations, and cable securing methods. It also covers topics such as cable marking, grounding, and bonding requirements to minimize the risk of electrical hazards.
Performance Testing and Evaluation
In order to ensure the reliability and performance of outdoor optical fibre cables, IEC 60794-1-3:2013 specifies various tests and evaluation procedures. These tests assess the cable's mechanical, environmental, and transmission performance under different conditions. Some of the tests include tensile strength testing, temperature cycling testing, and attenuation measurement. Compliance with these performance requirements is crucial to ensure the cables meet the necessary quality standards for outdoor use.
