BS EN 60793-2-40:2016 is a technical standard that defines the requirements and test methods for optical fibres and cables used in various communication systems. It specifies the performance parameters, such as attenuation, chromatic dispersion, and geometrical characteristics of these optical fibres and cables.
Importance of BS EN 60793-2-40:2016
The standard plays a crucial role in ensuring the reliability and quality of optical fibres and cables used in telecommunications. By providing specific guidelines and testing procedures, it helps manufacturers produce products that meet the required industry standards. Compliance with BS EN 60793-2-40:2016 ensures that the optical fibres and cables perform optimally, leading to efficient data transmission and reliable communication networks.
Main Requirements of BS EN 60793-2-40:2016
1. Attenuation: The standard specifies the maximum allowable loss of signal power, known as attenuation, for different types of optical fibres and cables. This parameter determines the distance over which the signal can be transmitted without significant degradation.
2. Chromatic Dispersion: It defines the limits for chromatic dispersion, which refers to the spreading of different wavelengths of light in an optical fibre. High levels of dispersion can cause signal distortion and limit the bandwidth capacity.
3. Geometrical Characteristics: BS EN 60793-2-40:2016 sets requirements for the geometrical properties, such as core diameter, cladding diameter, and concentricity. These parameters affect the ease of fiber optic cable installation and termination.
Testing Methods under BS EN 60793-2-40:2016
The standard provides several testing methods to evaluate the performance of optical fibres and cables. These include measurement of attenuation using an Optical Time Domain Reflectometer (OTDR), characterization of chromatic dispersion using the Pulse Delay Method, and inspection of geometrical characteristics using specialized tools like a Microscope or Optical Fiber Interferometer.
In conclusion, BS EN 60793-2-40:2016 is a critical standard that defines the quality requirements and evaluation methods for optical fibres and cables used in communication systems. Compliance with this standard ensures the reliability and performance of these components, leading to efficient data transmission and robust communication networks.
