What is EN 60793-2-70:2015?

Introduction

EN 60793-2-70:2015 is a technical standard that focuses on the specification and testing of optical fiber for use in telecommunication systems. This standard provides guidelines for the characteristics and performance requirements of various types of optical fibers. It plays a crucial role in ensuring the reliability and quality of optical communication networks.

Key Features of EN 60793-2-70:2015

EN 60793-2-70:2015 classifies optical fibers into different categories based on their transmission characteristics, mechanical properties, and environmental resistance. The standard specifies the following key features:

Attenuation: This refers to the loss of signal strength as it travels through the fiber. EN 60793-2-70:2015 sets limits on the maximum attenuation allowed for different categories of optical fibers.

Bandwidth: It defines the capacity of an optical fiber to carry data. The standard establishes requirements for both modal bandwidth (multimode fibers) and cutoff wavelength (single-mode fibers).

Geometrical specifications: EN 60793-2-70:2015 includes requirements for the core diameter, cladding diameter, and concentricity error of optical fibers.

Mechanical properties: The standard outlines tests for tensile strength, bend radius, and dynamic fatigue to ensure the fibers can withstand various installation and operating conditions.

Environmental resistance: EN 60793-2-70:2015 evaluates the fibers' resistance to temperature, moisture, chemicals, and other external factors that could affect their performance over time.

Testing and Certification

To comply with EN 60793-2-70:2015, optical fibers must undergo rigorous testing to determine their conformance with the specified requirements. Independent laboratories perform these tests and issue certifications to manufacturers whose products meet the standards. Some of the common tests include optical attenuation measurement, bandwidth measurement, geometrical measurements, and mechanical property testing.

Certification not only assures customers of the quality and reliability of optical fiber products but also facilitates compatibility between different fiber types from various manufacturers. It ensures that fiber-based communication systems can be seamlessly integrated, reducing potential disruptions in the network infrastructure.

Conclusion

EN 60793-2-70:2015 is a critical standard in the field of optical fiber telecommunications. By specifying the characteristics and performance requirements of optical fibers, it helps ensure the seamless integration and reliable operation of communication networks. Compliance with this standard, along with proper testing and certification, provides confidence in the quality and compatibility of optical fiber products from different manufacturers. This standard continues to support advancements in telecommunication technology and the growing need for high-speed data transmission.
