EN 60793-2-70:2015 is a technical standard that specifies the requirements for optical fibres used in telecommunication networks. It sets the standards for the physical and mechanical properties of these fibres, including their tensile strength, geometrical dimensions, and resistance to environmental conditions.
Tensile Strength and Geometrical Dimensions
The standard defines the minimum tensile strength required for optical fibres. Fibres must be able to withstand a certain amount of pressure before breaking. This ensures their durability and reliability in various deployment scenarios. Additionally, EN 60793-2-70:2015 stipulates the acceptable geometrical dimensions for optical fibres. This includes the diameter of the core, cladding, and coating, as well as the concentricity and ovality of the fibre.
Environmental Resistance
Optical fibres need to be able to function efficiently in different environmental conditions. The standard specifies the requirements for their resistance to temperature changes, moisture, and chemicals. Fibres should maintain their performance characteristics and structural integrity even when subject to adverse conditions. By adhering to these guidelines, manufacturers ensure that the fibres meet the necessary quality standards across a range of situations and environments.
Compliance Testing and Quality Control
EN 60793-2-70:2015 provides guidance on compliance testing and quality control procedures during the manufacturing process. It outlines the tests that need to be performed to evaluate the fibres' performance, such as tensile strength testing, attenuation measurement, and refractive index profiling. Compliance with these testing procedures helps ensure the consistency and reliability of optical fibres produced by different manufacturers.
In conclusion, EN 60793-2-70:2015 plays a crucial role in ensuring the quality, performance, and durability of optical fibres used in telecommunication networks. By complying with this technical standard, manufacturers can produce fibres that meet the required physical and mechanical properties, as well as resist various environmental conditions. This leads to better communication systems and improved reliability for end-users.
