EN 60793-14-2:2016 is a technical standard that provides specifications for the measurement and characteristics of optical fibers. This standard is part of the European Norm (EN) 60793 series, which covers various aspects of optical fibers. In particular, EN 60793-14-2 focuses on the requirements for single-mode fibres used in telecommunications.
Fiber Geometry
In order to ensure optimal performance, optical fibers must meet specific geometric requirements. EN 60793-14-2 defines these requirements, including core concentricity, core/cladding concentricity error, and cladding non-circularity. Core concentricity refers to the alignment of the fiber's core with respect to its outer layers. Cladding non-circularity measures the deviation of the cladding shape from a perfect circle. These parameters are crucial for minimizing dispersion and loss in fiber optic communication systems.
Attenuation and Dispersion
The standard also addresses attenuation and dispersion, two significant factors affecting the quality of optical signals transmitted through fibers. Attenuation refers to the gradual decrease in signal power as it travels along the fiber. EN 60793-14-2 specifies the maximum allowable attenuation for different wavelengths. Additionally, the standard provides guidelines for characterizing chromatic dispersion, which causes multiple wavelengths to spread and blur, limiting data transmission rates. Proper attenuation and dispersion management ensures reliable and efficient fiber optic communication.
Mechanical Properties
Besides optical performance, the mechanical properties of optical fibers are equally important. EN 60793-14-2 outlines requirements for tensile strength, impact resistance, and bending performance. Tensile strength measures the maximum force a fiber can withstand without breaking, ensuring its durability during installation and operation. Impact tests determine a fiber's resistance to external impacts that may occur during handling or accidental situations. Bending performance specifies the allowable bending radius of the fiber without significant signal loss or damage.
EN 60793-14-2:2016 serves as a comprehensive guide for manufacturers and users of optical fibers. By complying with the standard's specifications, companies can ensure the reliability and performance of their fiber optic products. Additionally, customers can make informed decisions by considering the technical parameters outlined in EN 60793-14-2 when selecting and implementing optical fiber solutions.
